“flu vaccine a bit less effective this year..”
Really less effective for those who didn’t have an injection and waited until now for their flu shot.
As usual in California, the flu kicks off with Thanksgiving with all of the travel for that holiday and college kids being off.
Then, it kicks into high gear about the week before Christmas with all the travel and again college kids flying and driving home for the holidays.
Throw in all of the air plane travel in flying germ pools aka air planes from all over America and the rest of the world to really jump/kick start the flu season with new variations of the flu virus.
My wife and I visited our local Kaiser health care clinic for the end of the calendar year sale on eye glasses and contact lenses.
Their line to get flu shots was huge. Also, it is too late for any good immunization. Many sounded like they had the beginnings of their personal flu and were sharing with others in the line.
I understand that it takes about 2 weeks after you get the flu shot
for the body's immune system to kick in
and provide through protection from that variant of the virus.
