My take on this is that this baby is going to be very precious to your daughter, and she wants to protect the baby from being infected with a preventable disease. As a grandmother I’d want to do that too, I’d never forgive myself if I passed something serious that I could have prevented on to somebody else, but particularly to a baby..
Your daughter is in charge in this situation, so either you take the vaccinations, assuming they are Public Health endorsed, or you resign yourself to not having close contact with your granddaughter whilst she is at her most vulnerable.
