I don't understand what you're asking. Vaccines are recommended because that's usually the best course of action. That doesn't mean that vaccines will work 100% of the time... if that's what you were asking. Safety...? We're not talking about experimental vaccines whose safety is not well understood. If you have specific allergies or specific medical conditions, I'm sure your doctor would either recommend an alternative that does not have that allergen or suggest some other course of action.

No doctor says "everyone should take all vaccines NOW". More info here: https://www.cdc.gov/vaccines/vpd/should-not-vacc.html
