Adult Immunization Flashcards
Key differences between live attenuated and inactivated vaccines
Live attenuated
- derived from viruses or bacteria which are modified or weakened in laboratories
-immunity is elicited by replication of the attenuated organism in the vaccinated person
- immune response is identical to that induced by natural infection
Inactivated vaccines
-produced by growing the bacteria or virus in culture media which are then subjected to heat or chemical agents
-incapable of replication inside the host
Types of vaccines and examples
Guidelines on timing and
spacing of vaccines
Multiple vaccines can be administered at the recommended schedule and time using different injection sites.
Two to three inactivated injectable vaccines can be given in the same visit.
Simultaneous administration of 2 live
vaccines can be given in same visit.
Two live parenteral vaccines can be given
together, with the 2nd dose of the same
vaccines usually administered after 4 weeks.
It is not necessary to restart the series of any vaccine due to extended interval between doses.
Vaccine doses should not be administered at less than the recommended minimum
intervals or earlier than the indicated
minimum age.
Not contraindications to vaccination
- Mild acute illness (with or without fever)
- A history of mild to moderate local reaction to a previous dose of the vaccine
- Breastfeeding
Transient precaution to vaccination
Moderate or severe acute illness with or without fever, results in postponement of vaccine administration until the acute phase has resolved
