Live Attenuated Vaccines
The live attenuated vaccines are produced with a small amount of the living virus or bacteria that is weak, allowing the body to react to the bacteria or virus but not become ill. Very rarely someone with a compromised immune system will become ill. The majority of patients with neutropenia have an intact immune system and the attenuated vaccine is safe.
Inactivated Vaccines
The inactivated vaccine stimulates a weaker response because the bacteria or virus has been killed. These vaccines may require boosters to maintain immunity.
