Is flu vaccination effective? Does it really help to do it in my age?

Get Vaccinated. The flu vaccine is very effective against the strains that are included in the shot and helps with some strains that aren't included. This year the shot immunizes against 4 strains and should provide better coverage for flu b which has often had incomplete coverage in the past. You cannot get the flu from the shot and it takes 2 weeks to develop immunity after your vaccine.
