How long does protection from vaccines last?

clarify ko lng regarding sa flu marami pong strains Ang flu kaya every year need mo mag pa shots. once mabigyan kna n Ng isang strain immune k n po Duon. pero if I'm not mistaken 144 Ang strain ng flu kya kahit every year k mag pa shots d k ma iimmune sa lahat. pero it helps n maprevent n mag ka flu k lalo n Yung mga common strains.

depende po ito sa sakit mommy kaya dapat talaga regular check-up kayo with the doctor. yung ibang vaccines po kasi like flu vaccine, every year dapat meron. yung iba naman, kailangan may booster shots para effective talaga.

It depends on the disease. Some diseases, you only need to take one or one round of vaccines. Some need vaccine boosters every few years. Some (like the flu vaccine) needs to be taken every year.
