Influenza Vaccine 2020

Influenza picture

The 2021 Influenza vaccine should be available around April/May.

Why and When should you get Influenza Vaccine?

  • Annual vaccination is required for two important reasons:
    1. Protection lessens over time
    2. The circulating influenza strains change each year and may not have been in the previous year’s vaccine
  • The best time to have the vaccine is prior to influenza entering the community, before the start of the winter season. This is generally April-May each year. Giving the vaccine no earlier than April is expected to provide better protection during the peak of influenza activity which is expected around August.  The vaccine can still be given later than May, even when influenza is already around in the community, as protective antibody levels can develop rapidly, from as little as four days after immunisation.
