Explain Antivirals Don't Help the Flu in Most Patients
Patients will ask about problems with this year's flu vaccine and whether they need an antiviral if they get the flu.
We know that influenza A H3N2 is the most common strain circulating now...and it has mutated since the vaccine was formulated.
That's why this year's flu vaccine is only about 23% effective...compared to up to 55% last season. The H3N2 strain is also more virulent...leading to more hospitalizations and deaths.
