Contraindications to vaccination

Although vaccines are an effective method for preventing disease infection, there are certain situations in which vaccines should not be administered to patients. Vaccines are safe for most patients because the FDA regulates both vaccine safety testing in the prelicensure stage and vaccine safety monitoring in the postlicensure stage of vaccine development. However, certain clinical scenarios may present contraindications and precautions to vaccination that dictate when vaccines should not be given.

As defined by the Center for Disease Control (CDC), a contraindication is a condition that increases the likelihood of a serious adverse reaction to a vaccine for a patient with that condition. In contrast, a precaution is a condition in a patient that might increase the chance or severity of a serious adverse reaction. Precautions may also compromise the ability of the vaccine to produce immunity (e.g. immunosuppression, so the immune system can't mount an adaptive immunity response). Many contraindications and precautions are temporary, allowing vaccines to be administered a later time after the condition has subsided (e.g. acute illness, pregnancy). Generally, vaccines should not be administered when a contraindication or precaution is present, although providers may decide under their discretion to administer vaccines when precautions are present (not allowed for contraindications) if the benefits of the vaccine outweigh the risk of an adverse reaction.

The CDC indicates that there are only four permanent contraindications for vaccines:
1) Allergy to vaccine component or previous dose of a vaccine
2) Encephalopathy (broad term for neurological disorders)
3) Severe combined immunodeficiency (SCID)*
4) History of intussusception (medical condition in which a part of the intestine into another section of intestine like a teloscope)*
*3 and 4 are contraindications to rotavirus vaccine.

In order to summarize the most common conditions that present as contraindications and precautions for vaccines, the following is a table adapted from the CDC's General Recommendations on Vaccinations:

Condition Live Vaccine Inactivated Vaccine
Allergy to Component C C
Encephalopathy -- C
Pregnancy C V*
Immunosuppression C V
Severe illness P P

Recent antibody-containing blood product

P** V

C=contraindication
P=precaution
V=vaccinate if indicated (no contraindication or precaution)
*except HPV
**MMR and varicella containing (except zoster vaccine) only
