Anthony Komaroff, MD, Internal Medicine, answeredSome people should not get certain vaccines or should wait to get them. For instance, children with compromised immune systems, such as those with cancer, may need to wait to be vaccinated. Anyone who has had a severe allergic reaction to a vaccine should not receive another dose. However, a person with a mild, common illness, such as a cold with a low-grade fever, can safely be vaccinated.
