Vaccines Flashcards
Destroys the viruses ability to replicate but keeps it intact so the immune system can recognize it
Inactivated
Weakens virus but doesn’t kill it
Live attenuated
Uses only a piece of the pathogen instead of a whole virus to cause immune response
Subunit
MRA enters the body which gives a code to create a protein that triggers an immune response
mRNA
Inactivated toxins that are produced by a bacteria, form of inactivated
Toxoid
Polio
Inactivated
Flu
Inactivated
Mmr chickenpox
Live attenuated
Hepatitis b, shingles
Subunit
Covid
mRNA
Diphtheria
Tetanus
DTaP
Toxoid
Process of cutting and recombining DNA fragments
Recombinant DNA technology
General response that neutralizes pathogens regardless of what they are
Innate immunity
Innate immunity barriers
Skin, secretions that move pathogens out of body
Immune response that Target specific pathogens
Adaptive immunity
Adaptive immunity defenses
Antibodies locate antigens (non-self antibodies) and stimulate immune response to kill specific antigen
Antibodies versus antigen receptors
Same protein, antigen receptors are on cell membrane of white blood cells and remain with cell that produced, antibodies are secreted and can circulate body
What is a vaccine
Introduces antigens from a pathogen so body can get a primary immune response
R- naught/r⁰
Average of how many people one sick person affects ex one sick person gets three others sick, r³
Percent reduction of disease in vaccinated population when compared to unvaccinated population
Vaccine efficacy
Risk formula
Infected people/total people
Vaccine efficacy formula
Unvaccinated risk - vaccinated risk/unvaccinated risk
Relationship between environment host and agent
Epidemiological triangle
Infant immune systems can’t handle so many vaccines in a short period of time
Infants are exposed to many germs everyday, vaccines only take up small fraction of babies immune response
Infection rates are low so vaccines aren’t needed
Community will disappear if too many people do this, everyone who is not vaccinated gives the disease more risk of spreading
Vaccines cause autism
No, Dr falsely linked MMR vaccine to autism, CDC says antigens in vaccines were the same between autistic and non autistic kids
Vaccines contain unsafe toxins
Do not contain toxic ingredients but have metals naturally found in bodies, only toxic if given a very large dose
Hygine and sanitation are responsible for infection
Hygiene and sanitation decrease spread of disease, vaccines stimulate the immune system while sanitation prevents spread of infection
