Q

Live Vaccines: General Principles

A

Not administered to immunocompromised patients
Usually not given if patient has febrile illness
If patient needs two live vaccines:

- Administer at least 4 weeks apart
Not administered in pregnancy
- Pregnancy should be avoided for 1 month after vaccination
Drug interactions
- Antiviral drugs
Separate IG administration from live vaccine administration
