Shragi,
There were many things wrong with your post but the mistakes at the beginning were so blatant I can’t help but address them.
“Nowhere in the toira are vaccines said to be muttar”
The Torah does not specify different kosher and unkosher medicines. It says v’raph y’rapeh, you must use doctors to heal someone (who you damaged). Chazal said that we follow the decisions of the best doctors or the majority of doctors. Therefore vaccination is required by the Torah.
“and it is completely illogical to believe that taking in a disease (along with mercury!) will protect you from it.”
You personally not understanding how viruses and immunity work does not mean that nobody understands it. It isn’t a big secret.
“Their effectiveness is highly doubtful given that the first vaccine was invented in 1796 and measles wasn’t declared eradicated in the US until over 200 years later!”
The MMR vaccine was developed in the early 1970s.
