Only the 3 that were required back in the early 1960s, which were:

~ Smallpox

~ Diphtheria/ Tetanus/ Pertussis (called DTP)

~ Polio (IPV)

I acquired natural immunity by getting sick from and recovering from: Chickenpox, measles, whooping cough, mumps, croup cough, strep throat, flu(s), Valley fever, mononucleosis, pneumonia, shingles, pleurisy, 1968 Hong Kong flu, stage III Cancer, and a 2017 early COVID-19 exposure (I think) that that kicked my ass.

Still alive and kicking.
