Flu Season 2019-2020
What viruses will the 2019-2020 flu vaccines protect against?
There are many different flu viruses and they are constantly changing. Flu vaccines protect against the three or four viruses (depending on the vaccine) that research suggests will be most common. For 2019-2020, trivalent (three-component) vaccines are recommended to contain:
– A/Brisbane/02/2018 (H1N1)pdm09-like virus (updated)
– A/Kansas/14/2017 (H3N2)-like virus (updated)
– B/Colorado/06/2017-like (Victoria lineage) virus
Quadrivalent (four-component) vaccines, which protect against a second lineage of B viruses, are recommended to contain:
the three recommended viruses above, plus B/Phuket/3073/2013-like (Yamagata lineage) virus.
When should I get vaccinated?
Because the timing of the onset, peak and end of flu seasons varies from year to year and cannot be predicted, it is difficult to say.
CDC (Centers for Disease Control and Prevention) recommends that people are vaccinated by the end of October or early November.
