Vaccine allergy

That's something to discuss with your doctor. If your doctor has advised for or against the vaccine and you still aren't sure, get a second or third opinion. There will always be some people who can't receive the vaccine. Your doctor will be able to advise you on that.

Are you allergic to or intolerant of sucrose? There's a difference. What are you symptoms? How do you survive, given that fruit and vegetables contain sucrose (far more than any vaccine dose)?

There's sucrose in vaccines to help the molecules keep their shape. The amount is miniscule.

Talk to your doctor or immunologist.
