There are no narcotics or other drugs in vaccines. Ask your doc if they think you're safe to have the jab. Too many people have had "risks" bigged up out of all proportion by people around them, some well-intentioned, some scaremongering. Not saying you, Ebbie, but if it's really not safe for you to have the jab then you are in a tiny minority.

Vaccines generally combat pathogenic organisms, pfr. As far as I know, that doesn't apply to the three conditions you mention.

And wear the mask and keep to two metres. But beware of non-settled science being mischaracterised as unqualified certainties, for example "masks still help."
