Because vaccines must be safe for use by as many people as possible, vaccines are developed in accordance with the highest standards of safety. Years of testing are required by law before a vaccine is licensed and distributed. Once in use, vaccines are continually monitored for safety and efficacy.
However, as with any medical procedure, vaccination has some risks despite the substantial, proven benefits. Individuals react differently to vaccines, and there is no way to absolutely predict the reaction of a specific individual to a particular vaccine. There may also be some religious or ethical considerations to weigh. Anyone who takes a vaccine should be informed about both the benefits and any potential risks or issues with vaccination.
