According to the Centers For Disease Control and Prevention, "About 2 weeks after vaccination, antibodies that provide protection against influenza virus infection develop in the body."
"It generally takes two weeks to develop immunity from the shot," says the website of The American Academy of Allergy Asthma & Immunology.
And according to University of Michigan Health System, "The flu vaccine becomes effective 2 to 4 weeks after you get the shot."

Actually it takes about 1 to 2 months. This is the best time to get it because it will be in full effect by the peak flu season.

about 10-14 days.
You have the best protection when you go every year.
A flu shot won´t prevent a common cold, but the real nasty flus will be much easier to sustain.

It takes a pair of weeks for the flu shot to grow to be powerful. however the shot does no longer assure which you will no longer get the glu, basically that in case you do get it it's going to be much less severe. I honestly have had the shot and that i'm merely improving from a splash of it. no longer this variety of undesirable concern.
