How Long Do Side Effects of Immunizations Last?
Most immunization side effects are mild and only last a few days.
VAPP
Albert Sabin
In 1961, Sabin’s live, attenuated polio vaccine replaced Jonas Salk’s inactivated polio vaccine that had been in use since 1955.
Attenuated Vaccines
An attenuated vaccine is one that has been weakened, so that it can’t make you sick, but will still trigger the creation of antibodies and an immune reaction.
VAPP
VAPP or vaccine-associated paralytic polio are cases of polio that are actually caused by the oral polio vaccine.
