Influenza 2021/2022: Suggested Best Practices for Pharmacies

Updated September 28, 2021

The purpose of this document is to provide best practice suggestions and considerations for the delivery of seasonal influenza vaccine by community pharmacists in fall 2021 in the context of the ongoing COVID-19 pandemic.

This document assumes that pharmacies/pharmacists providing seasonal influenza immunizations already meet their jurisdictional regulatory requirements to do so. Information provided here is intended to highlight considerations regarding new or adapted practices that pharmacies may need to implement as a result of the COVID-19 pandemic. For information on annual immunization guidelines, such as immunization schedules, please consult your provincial website or the Government of Canada's Provincial and Territorial Immunization Information web page.

These suggested best practices, originally developed by the Canadian Pharmacists Association (CPhA) in consultation with its National Influenza Preparedness Working Group for the 2020/21 flu season, have been updated for 2021/22. Guidance from the National Advisory Committee on Immunization (NACI) and the Public Health Agency of Canada supersedes all considerations and suggestions in this document. Furthermore, pharmacy regulators in some provinces have already issued COVID-19 guidance, which must be consulted prior to proceeding with any measures outlined here. Following that, any additional corporate policies (including guidance from a central office, if applicable) must also be taken into consideration.

Challenges in 2021/22

With expected high patient demand for influenza immunizations consistent with the 20/21 season, and a fourth wave of COVID-19, community pharmacy is preparing for a challenging 2021/22 influenza season. Pharmacists are planning how to manage the additional time, tasks and supplies they will need to provide immunizations safely to their patients, while protecting themselves and their staff.

Specific challenges include:

  • Ongoing COVID-19 activity, which may continue to stress public health capacity
  • Continued need for physical distancing and other infection control procedures
  • Increased demand from patients for influenza immunizations
  • Increased risk to patients seeking influenza immunizations of contracting both influenza and COVID-19
  • Reduced access to immunization services from other providers
  • Shortages of seasonal influenza immunization vaccines and supplies
  • Lack of awareness regarding updated guidance on COVID-19 and influenza vaccine co-administration (See NACI recommendation on co-administration)

Some pharmacies may also be challenged by:

  • Having only 1 pharmacist on staff at a time or no overlap
  • Smaller footprint with limited space for patient flow/waiting areas, depending on whether capacity limitations are restricted during the fourth wave
  • High volume with many patients coming into the waiting area
  • Curbside pickup or delivery services with no access to the pharmacy by the public
  • Households seeking influenza immunizations together (as encouraged by NACI)
  • Co-administration/individuals seeking multiple immunizations or other services at the same time as influenza immunization (as encouraged by NACI), specifically those seeking first or second COVID-19 shots.

Adaptations to influenza immunization services 

In order to accommodate what may be changing conditions as well as demand fluctuations, pharmacies may need to adapt their operations as follows:

  • Anytime walk-in immunizations (not recommended for high-volume pharmacies)
  • Dedicated hours for walk-in immunizations
  • Appointment-based model for individuals or households
  • Special hours for vulnerable patients, including closing the pharmacy to foot traffic during these hours
  • Immunizations off-site (e.g., home visits, congregate locations, workplaces)
  • Booking other “open spaces” such as community halls
  • Temporary structures co-located with the pharmacy (i.e., parking lot)
  • Drive-through services (i.e., immunizing patients in their vehicles)

IMPORTANT: If pharmacies choose to use off-site or drive through models to provide immunizations, remember to ensure that such activities are authorized by your jurisdictional regulation and covered by your liability insurance.

Key Workflow Principles

Flu workflow

No matter which delivery model your pharmacy chooses, your influenza immunization workflow should strive to:

  • Maintain physical distancing between individuals
  • Minimize the number of patients entering the pharmacy and number of pharmacy staff interacting with them
  • Minimize the length of time patients spend in the pharmacy and in close contact with any pharmacy staff
  • Reduce the transfer of objects (e.g., paperwork, pens) between all individuals
  • Incorporate contactless or paperless processes for certain elements of information gathering and distribution, patient registration, documentation, adjudication, payment, and record-keeping wherever possible
  • Account for all other COVID-related infection control measures to protect staff and patients and to minimize the spread of infection (e.g., screening patients, increased cleaning and disinfecting protocols, use of PPE)

Key considerations 

Documentation and Forms

Contact Tracing

The immunization and patient information you collect, document, transmit or adjudicate and how you do so will depend on your jurisdictional requirements, corporate policies, pharmacy information management systems, and any other technology platforms you may use. It is beyond the scope of this document to provide best practices that consider all these different factors.

Pharmacies may wish to consider:

  • Documents that patients can complete (via website, email or some other means) and submit ahead of time in a secure manner
  • Documents that patients can access (via website, email or some other means), complete and bring in hard copy to the pharmacy (this may minimize patient time in the pharmacy but also may increase the transfer of objects between individuals)
  • Adding COVID-19 screening questions to existing immunization screening forms to streamline workflow while maintaining a record for contact-tracing purposes (this will depend on jurisdictional requirements)
  • Being aware of possible changes to patient documentation with respect to vaccination passports, which may emerge in fall/winter 2021/2022

Scheduling Appointments/Hours

Flu Virtual Care

In order to control workflow and minimize the number of patients in the pharmacy (or immunization space), pharmacies may consider adopting a service model where patients register in advance for an immunization appointment at a specific time.

  • Schedule appointments for individuals approximately every 15 minutes
  • Limit the number of individuals attending an appointment to the patient(s) receiving the immunization and 1 essential caregiver, if required (e.g., parent; caregiver to elderly patient)
  • Consider immunizing household members together (which may require longer appointment times)
  • Schedule appointments online, by email, by phone or other method
  • Provide appointment reminders by text, email, phone or other method
  • Consider options or processes to remind patients to contact the pharmacy if they need to cancel or reschedule their appointment, or for pharmacy staff to contact patients in the event of a cancellation/change in schedule

The process you use to schedule appointments or send reminders may also provide opportunities to communicate with patients that may help minimize the time they spend in the pharmacy when they come in for their immunization. Consider:

  • Pre-screening patients for COVID-19 (via phone conversation with staff on the day of the immunization) or providing pre-screening information to them, and to query whether the patient has had both COVID-19 shots and explain that they can be co-administered with the flu shot if applicable. 
  • Providing patients with immunization documentation that may be completed and/or submitted ahead of time (where feasible)
  • Updating patient files
  • Obtaining information on patient preferences or special needs
  • Confirming patient eligibility for publicly funded vaccines (where applicable)
  • Providing patients with specific instructions on new procedures or what to expect
  • Providing patients with an opportunity to cancel or reschedule their appointment, if needed
  • Providing the pharmacy with an opportunity to cancel or reschedule the appointment, if needed
  • Answering any other questions

See “Communicating with Patients” for more details.

Screening for COVID-19

Flu workflow

Patients must be screened for COVID-19 before being immunized; immunizations should not be provided to patients who screen positive. Patients should be instructed to self-screen before coming into the pharmacy for their immunization, then be actively screened by a staff member shortly before the immunization is provided. Ideally, this active screening should be done before the patient enters the premises where the immunization will take place (and preferably before any vaccines are prepared for the patient).

Patients who screen positive for COVID-19 should be encouraged to be vaccinated for both influenza and COVID-19 after testing negative for COVID-19 and can be vaccinated once they come out of isolation.

Passive screening can be done via:

  • Online self-screening tool available to patients (e.g., on pharmacy’s website, via an appointment booking system) when they make their immunization appointment
  • Online self-screening tool provided to patients on the day of their immunization (e.g., via email, text link)
  • Posters or signage at the entry to the pharmacy/immunization space with self-screening criteria and instructions. Signage could also incorporate:
    • QR codes or URLs linked to online self-screening tools
    • Video instructions

Any passive screening tools should take your patients’ language and accessibility requirements into consideration, as well as their knowledge and comfort with digital technology. Passive screening tools must provide patients with instructions on what to do should they self-screen positive for any factor.

Active screening can be done:

  • By phone call with a pharmacy staff member on the day of the immunization appointment
  • In the patient’s vehicle by a pharmacy staff member when the patient(s) arrives for the appointment
  • At the entry to the pharmacy by a pharmacy staff member when the patient(s) arrives for the appointment

Pharmacy staff carrying out active screening should be wearing all appropriate PPE to protect themselves and must be prepared to instruct patients on what to do should they screen positive for any factor.

NOTE: Some of the reported reactions to an influenza immunization (fever, headache, muscle pain) may be similar to current screening criteria for COVID-19. At the moment, NACI and PHAC are still recommending that all patients should be advised to consider any symptoms as potential COVID-19 symptoms, regardless of any other possible cause, and follow any local public health guidance regarding isolation, monitoring or testing for COVID-19. This includes any policies established for school attendance.

Preparing Your Pharmacy/Immunization Premises

Steps to consider when preparing your premises to accommodate an influx of patients getting immunizations while maintaining physical distancing and other infection control procedures:

  • Determine limit on the number of people who may enter the pharmacy (or immunization space) at the same time, based on pharmacy size, physical distancing requirements and jurisdictional legislation
  • Minimize patient movement and contact via:
    • One-way traffic flow
    • Separate entrance and exit, if possible, and limited access points  
    • Indicators on the ground to denote which direction patients should move and how far they should stay apart
    • Tables or other distance barriers to add distance between patients
  • Determine required functional areas for service delivery (“stations”) and plan space allocations
  • Separate stations 6 feet/2 metres apart where possible or separate stations/spaces by plastic sheeting barriers or plexiglass barriers. Separate rooms for different functions are ideal but likely not possible in many pharmacies. For all stations, consider:
    • Positioning hand sanitizers at key stations
    • Ensuring all surfaces that patients may come in contact with (e.g., chairs) can be easily cleaned
    • Ensuring adequate air flow or ventilation in all patient areas
    • Ensuring access to sufficient amounts of cleaning/disinfection products
  • Maximize ventilation by ensuring that heating, ventilation and air conditioning (HVAC) systems are in good working order. Drawing as much fresh air as possible from outside will decrease the concentration of aerosols that may be suspended in the air, and reduce the chances of SARS-CoV-2 spread if those aerosols happen to contain the virus. If the weather and facilities permit, open a window.

Individual stations may include:


  • Active patient screening for COVID-19 by staff prior to immunization
    • Depending on your physical set-up, this might take place at the dispensary, at the entrance to the pharmacy, outside the pharmacy or even in the patient’s vehicle
  • Patient check-in and immunization form completion
    • Consider having patients receive and complete forms before entering the pharmacy to reduce time spent in the pharmacy. This may include:
      • Completing and submitting digital forms online, if your systems allow
      • Printing and completing hard copy forms at home and bringing them to the pharmacy (although this may increase the transfer of objects between individuals)
    • If patients are completing forms at the pharmacy, minimize the sharing of items such as pens or clipboards
    • Jurisdictional requirements for obtaining and/or documenting informed patient consent will apply

Flu workflow

  • Pre- or post-immunization waiting/observation space
    • Arrange seating 6 feet/2 metres apart in the waiting area
    • Remove all non-essential and other shared items from exposed surfaces (e.g., magazines, toys)
    • Consider instructing patients to wait outside the pharmacy or even in their vehicle until called in for their immunization
    • NACI has issued the following recommendations regarding post-immunization observation time:
      • Maintain current post -vaccination observation period in settings that can adhere to appropriate infection control measures to reduce transmission:

        • Maintain 15 minutes post-vaccination observation period (30 minutes if specific concerns regarding vaccine allergy)

      • Shorter observation period (5-15 minutes) only when distancing in post-vaccination areas cannot otherwise be maintained (discretionary recommendation):

        • This is secondary to insufficient evidence to support a standardized reduced post vaccination observation period

        • This shorter period to be considered only if recipient meets criteria specified in the attachment (e.g. no h/o allergy, post vaccine reaction, accompanied by a chaperone to monitor etc.)

  • Immunization area
    • Set up patient chair so that the pharmacist is not required to be directly in front of or leaning over patient while providing immunization
    • Patients and their accompanying persons should be asked to wear an appropriate mask or face covering. 
  • Area for staff PPE donning, doffing and disposal (see next section)

Personal Protective Equipment (PPE) Requirements

PPE needs for all activities related to the delivery of immunizations in the pharmacy should be evaluated using a point-of-care risk assessment approach and based on public health guidance. The differential risks of injectable vs. nasal formulations should be considered.

Remember to ensure a well-ventilated area in the immunization space and avoid overcrowding to minimize airborne transmission of COVID-19.

For immunization services provided to asymptomatic patients where staff will be within 6 feet/2 metres of the patient, without a barrier between them, the following PPE measures are suggested:

Contact Tracing

  • Consider sessional use for eye protection, masks and gowns (if worn). A session is defined as a period of time where a health care worker is undertaking duties in a specific setting or exposure environment, such as a 4-hour shift as designated vaccinator. A session ends when the worker leaves the environment
  • Wear eye protection (face shield or goggles) for duration of session; disinfect or dispose of after each session
  • Wear surgical/procedural mask for duration of session; replace sooner if it becomes damp, soiled or damaged
  • Gowns may not be required. Consider gowns in instances where vaccinator will be required to manage large numbers of patients; dispose or disinfect at the end of each session; in situations where gowns are not required, some pharmacists choose to wear scrubs sessionally when providing influenza immunizations
  • Gloves are required only for nasal vaccines. Depending on their own specific point-of-care risk assessment, some pharmacists may also choose to wear gloves for influenza injections; if worn, they must be replaced after each immunization (sessional use or use of hand sanitizer or bleach solution on gloves for repeated use are not recommended)
  • Review proper donning, doffing and hand hygiene processes with all staff, as well as consider posting signage in pharmacy to help remind staff of best practices for infection prevention and control.

Follow all other donning, doffing and hand hygiene best practices.

Infection Prevention and Control Measures

  • Perform routine environmental cleaning, especially in frequently visited areas (e.g., waiting area, registration area, door handles, washrooms) and on high-touch surfaces at least twice a day
  • Clean equipment shared with multiple people (e.g., pens, clipboards, chairs, tablet if digital information and consent performed) after each use
  • Station hand sanitizers at main areas of the pharmacy, including the entrance, exit, registration area, immunization area, waiting room and other areas of patient contact  
  • Clean hands using alcohol-based hand sanitizer containing 60–90% alcohol; alternatively, wash with soap and water for at least 20 seconds
  • Clean and disinfect immunization area (e.g., chairs, table, door handles) after each patient immunization
  • Use sanitation verification logs to ensure areas are cleaned regularly  

Preparing Your Staff


  • Where possible, designate staff to specific tasks for the duration of their shift. Consider dividing pharmacy staff into separate teams to prevent overlapping shifts
  • Consider which tasks can be performed by a pharmacy student, intern, technician or assistant under supervision. Depending on your service model, immunizations may also be performed by a pharmacy technician, nurse or other health care provider
  • When scheduling shifts and appointments/sessions, ensure the duration accounts for breaks for the team member. Consider having your designated immunizer work for no more than 4 hours before a break
  • Ensure staff members are trained on your pharmacy’s immunization protocols, injection-related policies, appropriate PPE use, hand hygiene, and infection prevention and control procedures
  • Before each shift, screen staff members for COVID-19 symptoms or potential exposure to COVID-19. Staff who screen positive should not be working in the pharmacy
  • Continue to implement other pandemic sanitary measures as specified by public health and/or your provincial pharmacy college
  • Instruct your staff on what to do if a patient screens positive at any time during the service. This may include:
    • Not performing the service
    • Collecting the patient’s name, phone number and date/time at the pharmacy (if the information has not already been obtained) in the event it is required for contact tracing
    • Instructing the patient to return home and call their local public health unit for more guidance
    • Wearing appropriate PPE and cleaning areas and surfaces touched by the patient
  • Consider strategies for managing patient situations that may create COVID-19 infection risks (e.g., a crying or thrashing child)
  • Keep up-to-date with emerging information and guidance around COVID-19 so that pharmacy staff are prepared to answer any patient questions 

Summary of Workflow Tasks

If possible, assign 1 individual to be the designated vaccinator for the duration of the immunization session(s). Other staff may assist with tasks where appropriate. Depending on jurisdictional regulation, certain tasks can be done by pharmacy technicians, assistants or even students.

Before the patient arrives at the pharmacy

  • Book and confirm appointments
  • Provide immunization documents to patients (where feasible)
  • Gather patient information (e.g., update patient file; confirm eligibility, preferences, special needs)
  • Provide instructions

When the patient arrives at the pharmacy

  • Screen patient for COVID-19
  • Direct patient where to wait (e.g.,inside the pharmacy, outside the pharmacy, in their vehicle)
  • Provide patient with immunization forms, if not provided beforehand
  • Answer patient questions, confirm eligibility 
  • Obtain any patient-specific information that is needed by the vaccinator (e.g., which arm, if giving injection)
  • Scan or otherwise enter immunization forms into pharmacy information management system (i.e., process the “prescription” and transmit information to vaccinator)
    • Ensure that patient contact information (name and contact number), plus the time and date the patient visited the pharmacy, is clear and easily accessible if needed for contact tracing purposes
  • Alert patients (in person, by phone or by text) when they may come into the immunization area
  • Consider identifying patients who are most at risk and should receive the influenza vaccine:
    • People at risk of severe COVID-19-related illnesses (adults over 65 years of age and/or with chronic health conditions)
    • People capable of transmitting influenza to those at high risk of severe and critical illness related to COVID-19

When delivering the immunization

  • Don PPE for the session
  • Stage the chair/room appropriately as per patient requirements; ensure vaccinator is beside patient (not leaning over or in front of patient)
  • If providing immunizations to a household group at the same time, consider preparing their vaccines and other supplies in a batch; consider use of pre-filled syringes where possible
  • Review and complete immunization forms with patient (which may be in hard copy of digital, depending on your pharmacy information management systems)
  • Consider administering all adult vaccines for other vaccine-preventable diseases that the patient requires to optimize vaccinations and minimize visits to the pharmacy
  • Instruct patient to face away from vaccinating pharmacist while delivering injection
  • Perform hand hygiene
  • Deliver immunization
  • Perform hand hygiene
  • Instruct patient where and when to wait post-immunization

Between and after immunizations

  • Clean and disinfect immunization area, patient waiting area (if in the pharmacy) and any other stations
  • Monitor patient flow and adherence to physical distancing protocols
  • Ensure patient remains in designated waiting area for required length of time; notify patient when free to go
  • Scan immunization documentation into pharmacy information management system (if not done previously)
  • Complete adjudication/billing
  • Provide patient with immunization record/receipt

Communicating with patients

Before the patient arrives at the pharmacy

Provide instructions and procedures to patients in advance (e.g., via website, using QR codes, email, video).
Regardless of service model, patients should be instructed to:

  • Self-screen for COVID-19* before coming to the pharmacy. Service cannot be performed on patients who:
    • Have tested positive for COVID-19 and have not been cleared
    • Demonstrate any COVID-19 symptoms (on day of service)
    • Have experienced any COVID-19 symptoms within 2 weeks of service
    • Have travelled out of the country within 2 weeks of service
    • Are living with an individual who currently has COVID-19 or has been out of the country within the last 2 weeks
    • Are under self-isolation

*Criteria may vary based on local or jurisdictional case definition.   

  • Wear some form of mask or face covering to receive service. If patient (or any essential companion) does not have a mask/face covering, the immunization cannot be performed. Pharmacy staff should be prepared to either ask patients to return home or alternatively provide them with a medical mask. Exceptions are permitted for children (2 years of age and under), patients with breathing difficulties, patients who may be unable to remove a mask without assistance or patients who have another medical condition preventing them from wearing a mask
  • Wear loose clothing with short sleeves to allow access to immunization site
  • Arrive on time, not early, to avoid crowding and to maintain physical distancing
  • Minimize the number of individuals entering the pharmacy who are not being immunized (e.g., 1 caregiver for a child; where possible, no siblings unless also being immunized)
  • Contact the pharmacy if patient needs to cancel or change the scheduled appointment/immunization time
  • Be aware of any new COVID-related policies or procedures, such as:
    • Advance completion of screening forms (if available)
    • Where to wait for service
    • How long (and where) to wait post-immunization
    • Any situational instructions (e.g., If using “drive-through” service, pharmacy staff should encourage patients to leave their car doors unlocked during observation time after receiving flu shots, to ensure staff can access patients if additional care is needed.)

Pharmacies should be proactive in informing patients that COVID-19 and influenza vaccines can be co-administered so that the decision is not made on the day of administration in the pharmacy (where applicable). 

Further instructions to patients on what to expect when they arrive at the pharmacy will depend on your service model and pharmacy information systems.

At the pharmacy

Develop and post signage that provides similar instructions and procedures to patients regarding COVID-19 screening and processes. Consider QR code scanning, large posters or videos.

In addition, materials should further instruct patients to:

  • Follow the pharmacy’s check-in and waiting area procedures, which may include waiting in a designated area, waiting outside the pharmacy or even waiting in one’s vehicle
  • Follow all directional and physical distancing signage
  • Respect posted limits of number of individuals allowed in the pharmacy at any one time
  • Be aware of how long to wait after immunization and where to wait
