The G2 on the ongoing rows about the HPV vaccine.
I was given the rubella (german measles) vaccine aged 11. As far as I still understand it was on the premise that one day I would be married and have children, and, if during one of those pregnancies I caught rubella it would affect the baby.
I don't understand how this situation is different. It protects against a future chance of infection. The method of infection isn't important to me. It's a matter of protecting the child now against something that might occur in the future.
