Intranasal Flu Vaccine

Description

Vaccination is the best protection against the flu and its complications. The flu vaccine does not protect against the common cold and respiratory infections caused by other viruses.

The intranasal flu vaccine must be administered once every fall. It is given via a nasal spray, one squirt in each nostril. In most cases, this type of vaccine can be administered even in the presence of nasal discharge.

People aged 2 to 59 can receive the intranasal vaccine unless otherwise contraindicated. However, this vaccine is given free of charge only to some children between the ages of 2 and 17 as part of the Flu Vaccination Program. To learn more, see the List of People Eligible to Receive the Injectable Vaccine for Free.

For a child younger than 9 years, 2 doses of the vaccine, given 1 month apart, are required when it is a first vaccination against the flu.

For the 2017-18 season, the intranasal vaccine offered under the Québec Flu Vaccination Program contains the following strains:

  • A/Michigan/45/2015 (H1N1)
  • A/Hong Kong/4801/2014 (H3N2)
  • B/Brisbane/60/2008
  • B/Phuket/3073/2013

As the viruse contained in the vaccine may be found in nose secretions, avoid close contacts with severely immunosuppressed people requiring protective isolation, for 2 weeks following vaccination.

Where to get Vaccinated
