You think it changed because you never knew anything about vaccines prior to Covid and you’re no better informed now. Apparently the memo you read wasn’t worth much.
Vaccines did exactly one thing when Edward Jenner used cowpox to innoculate against smallpox in the 1700s. They train the immune system to be ready to combat a particular disease. They still do that same one thing now.
