Q

What are the 2 different types of vaccines? What are the difference?

A

active or passive

Active immunization: induces immunity by vaccination with a vaccine or toxoid
(inactivated toxin)

passive immunization: includes transplacental transfer of maternal antibodies and administration of antibody, either as immunoglobulin or monoclonal antibody

aka mom gets the shot and passes it to baby, or IVIg

Q

What is a live attenuated vaccine? How many doses are usually needed?
