Babies can get vaccinations after a week of stopping medication when they get well from a cold. The immunity of the baby’s body will be reduced after the cold, and the other functions of the body will also be weakened. After the cold symptoms disappear, the immunity of the body is not fully restored, and the other functions of the body also need to be repaired, plus the medication used during the cold, and it takes some time for the medication to be completely metabolized in the body, because the vaccine is made by artificially attenuating and inactivating bacteria, viruses and other pathogenic microorganisms and their metabolites. If your baby gets well from a cold and is given vaccination too early, the residual antiviral or antibiotic drugs in the body will easily kill the vaccine, resulting in vaccination failure. In addition, if your baby gets well from the cold, premature vaccination will lead to the lowering of the immunity that has not been restored again, causing the aggravation of the symptoms of side effects after vaccination, which is also not conducive to the formation of antibodies to this vaccine.
