[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]OP, there are two types of immune responses: innate and adaptive.

Innate immune responses are generalized, not specific to the antigen. They unfold the same way every time. They also happen immediately. Fever is an innate response.

The adaptive immune system is antigen-specific. Adaptive responses include making the specific antibodies needed to neutralize this antigen, and developing the specific memory cells that help your body recognize and defend against that pathogen in the future. Because the adaptive immune system is quite complex, and involves some degree of “learning” it takes quite a bit longer than the innate responses. [/quote]

This is OP and this is what I was looking for. I had no idea. Thank you![/quote]

AND THIS IS WHAT IS SO SAD ABOUT OUR PUBLIC HEALTH AND EDUCATION IN THIS COUNTRY. I would even bet the OP is college- educated. FFS. [/quote]

The info is there and available to anyone who wants it, but vaccine misinformation is just everywhere and unrelenting and it drowns everything else out. The idea is to create doubt so hesitancy seems “reasonable”.

It can also be confusing when some vaccines, like rabies, are prescribed only after exposure (excepting vet staff who are exposed regularly). Even the MMR and Tetanus vaccines can be partially effective when taken after exposure. It can be very easy to miss that for COVID and flu, waiting until you’re in the throes of it is too late.
