Hi everyone, having a reaction to a vaccine is actually a really good sign provide not a adverse one. It means that your immune system is working. @Fraser explains this very well in her post above. Always to to talk to a doctor if you are concerned about a reaction. I feel a bit sorry for the very old because most of them don't have any reaction to any vaccine because their immune systems are strong.
