A member asked:

About 15 years after receiving the gardasil9 hpv vaccine, if the antibody goes down, do t cells still have immune memory? (how long do t cells normally have immune memory, even without an antybody?) please help me?

A doctor has provided 1 answer

Generally for a long time but there is no specific study which has measured it against hpv
