tri verus quad flu shot
Flu shots are available now. I discovered a couple years ago you can get one that covers 3 or 4 strains, but you need to ask for the 4-strain one. Probably a "marketing" gimmick, but figured the broader protection the better.
The "Quadivalent vaccines protect against 4 strains of the flu, A/H3N2, A/H1N1, and 2 strains of influenza B."
The trivalent ones only cover 1 strain of influenza B.
I always call ahead to see if the pharamacy has the quadivalent one.
fwiw
