- Advisory Committee on Immunization Practices (ACIP)
- CDC
VIS
vaccine info statements, handed to pt before admin
found on CDC website
Thimerosal
mercury-containing preservatives.. in some vaccines. no evidence that it poses a risk for autism.
in some multidose flu vacine…
Gelatine-containing products
from pigs, used in some vax as stabilizer
immunity
antigen- foreign
antibodies- immunoglobins, made or given
inactive vaccines
used kill version of a wild virus or bacteria that causes the disease. CAN NOT replicate and cause disease.
Less affected by circulating antibodies than live vaccines
limitation: immunity is not as strong as with live vaccines
Boosters: may be required for ongoing immunity
Polysaccharides, conjugated and recombinant vaccines
target a section of the organism, such as protein, sugar or capsid (outer casing)
these are types of vaccines in the inactive vax group
Polysaccharide Vaccines
molecules taken from the outer layer of encapsulated bacteria (such as pneumoccal serotypes; each serotype matches a circulating strain of the organism).
ex: Pneumovax 23
Do NO produce a good immune response in <2 years
inactive-vax group
Conjugated Vaccines
polysaccharides (sugar), molecules from the outside layer of encapsulated proteins and JOIN the molecules of carrier proteins.
increase immune response in infants, and antibody booster response to multi doses of vax
ex. Prenar 12, Menactra
inactive-vax group
Recombinant vaccines
a gene segment of a protein from the organism is inserted into the gene of another cell, such as a yeast cell, where it can replicate.
ex: Gardasil 9, FluBlox Quadrivalent
inactive-vax group
Toxoid Vaccines
vaccine targes a toxin produced by the diese
ex: diphtheria toxoid vac, tetanus toxoid vax
inactive-vax group
mRNA
vaccine gives instructions to the body’s cells (in the form of mRNA) to produce a protein specific to the pathogen, which then triggers an immune response
ex: covid 19 vax
inactive-vax group
Live vaccines
similar to the actual disease, provides a strong, long-lasting immune response
Limitations: 1) pt who are immunocompromised may not be able to halt replication; could cause the disease 2) circulating antibodies could interfere w/ vaccine replication
common live vax
MICRO-VY
MMR
Intranasal influenza
Cholera
Rotavirus
Oral Typhoid
Varicella
Yellow Fever
tuberculin skin test (TST)
live vax can cause a false-negative
1) give live vax the same day as the TST
2) wait 4 weeks after live vax to perform TST
3) admin TST first, wait 48-72 hrs to get results, then give live vax
General rule for all vax
timing and spacing
- can be usually given at the same time (same visit/day)
—– except in pt w/ asplenia, Prevnar and Menactra should be separated by 4 weeks - multi live vax can be given on the same day, if (not given on the same day) space 4 weeks apart
—- except no separation is required for oral rotavirus vax - vax series requires >1 dose, intervals can be extended w/o restarting but should not be shortened in most cases
interval between antibody-containing products and MMR and MMRV
minimum of 3 months and up to 11 months, depends on product and some
live vax and antibody
timing and spacing
- MMR and varicella-containing (MMRV) products require separation from antibody-containing products (e.g. blood transfusion, IVIG)
—-vax–> 2weeks–> antibody-containing products
—-antibody-containing products–> 3 months or longer–> vax - simultaneous admin of vax and antibody (inform of immunoglobulin) is recommended for post-exposure prophylaxis for certain diseases (e.g. hep A &B, rabies, tetanus)
pt should be monitored for
15 min
