I'm equally confused. The vaccine isn't like some force field that keeps the virus away and out of your body. It only helps if/when the virus gets into your body also known as being infected. Right?
- standardUser 5y agoIf you already have an immune response to the virus, your body has a chance to destroy the virus before an infection can take hold. Same with any vaccine. Then normal course of any infection is for the infection to take hold and your body then works on an immune response, eventually killing the infection (one would hope). Previous infection means you already have the immune response ready and waiting (though that can fade over time). Vaccines simply mimic your bodies response when recovering from an infection.
