Seasonal Influenza

Canadian public health authorities continue to offer four-strain quadrivalent influenza vaccines (QIVs). QIVs can help protect against four different influenza virus strains, including the two influenza A strains and two influenza B strains. QIVs help reduce the possibility of B strain mismatches, which could result in better protection against the flu, enhanced public confidence and better annual vaccine uptake.

Annual immunization is the most effective method of preventing influenza and its complications. The effects of the flu vaccine can wear off, so you need to get a new one every year to stay protected. It’s a simple action that can save lives.

Influenza immunization programs focus on three groups of people:

  • those at high risk of influenza-related complications
  • those capable of spreading influenza to individuals at high risk of complications
  • those who provide essential community services

With the immunization of RNs, CNA’s position is that registered nurses should receive the vaccine each year to protect themselves, their families and those in their care. For further details, see the CNA position statement [PDF, 272.9 KB]

Updated recommendations for intranasal flu vaccine

The National Advisory Committee on Immunization (NACI) has reviewed the evidence on the live attenuated influenza vaccine (LAIV), also known as the intranasal flu vaccine. NACI continues to recommend routine, annual influenza vaccinations using a quadrivalent formulation for children and adolescents aged 2-17 years. NACI no longer recommends the preferential use of LAIV in children and adolescents. In addition, because of the burden of influenza B disease in children and the possibility for strain mismatch, NACI continues to recommend the quadrivalent influenza vaccine. Read more.

High-dose influenza vaccine approved for use in adults > 65

A high-dose influenza vaccine has been approved for use in Canada for persons 65 years of age and older. NACI concludes that there is evidence that high dose trivalent inactivated influenza vaccine for older adults should provide superior protection compared with the standard dose intramuscular vaccine.
