Module 4 - Types of Immunizing Agents and Their Composition Flashcards
What are the 3 main types of vaccines?
- live attenuated vaccines
- inactivated vaccines
- subunit vaccines
What does attenuated mean ?
that the virus is weakened
What type of vaccine is the closest to developing immunity from a an actual infection?
live attenuated vaccine
What advantages to live vaccines have over other vaccines?
- they grow in the body and are transmitted to other areas of the body so the immune system develops an effective immune reaction to them, just like if you were to come in contact with a natural infection
- these vaccines lead to high antibody levels and most will only need one or two doses to lead to long-term immunity
Who cannot receive live vaccines?
- immunocompromised
- pregnant patients
When is corticosteroid use and live vaccines not contraindicated ?
- short-term therapy
- low dose therapy
- administered topically, inhaled, or locally injected (ex. to a joint)
Live vaccines have live agents so ____ conditions are especially important in order for them to maintain their full potency.
storage
List some examples of live attenuated vaccines.
Vaccines for:
- influenza (nasal spray form)
- measles
- mumps
- polio
- rotavirus
- rubella
- typhoid
- yellow fever
- varicella
- herpes zoster
______ vaccine contains a suspension of whole-killed bacteria or virus
Inactivated
Is there a risk of uncontrolled replication of an inactivated vaccine?
No - therefore you can give to immunocompromised patients
T or F: inactivated vaccines tend to have a lower immune response than live vaccines
true
Is the site and route of admin more important with live vaccines or with inactive vaccines?
With inactive vaccines because non-live vaccines activate an innate response ONLY at their sites of injection
Would an IM or SC injection be better for non-live vaccines?
IM - want to give them in well vascularized muscles
Inactivated vaccines almost always require _____ doses
multiple
With inactivated vaccines, dose the 1st dose provide protection?
No - it primes the immune system. A protective immune response develops after the second or third dose
