Early reports showing that flu shot may be only 10% effective
The flu season may be worse this year.
That is because the vaccine is not as effective in preventing H3N2, which is expected to be the dominate strain.
It doesn’t help that H3N2 is also a more severe form of the flu.
Despite the flu shot not being as effective against H3N2, experts are still encouraging anyone over the age of six months to get a flu shot.
The vaccine still protects against other flu strains.
