Vaccinations (Peds)
Active
Passive
Adult immune system
- Ig crosses the placenta and cover baby
- after 6m :calendar: they wear off (also when immunodeficiencies appear)
- IF mom doesn't have immunity, we can give IVIG (to :baby::skin-tone-3:)
-
Priming the immune system
- APC presents antigen, B cells make Ig
- B cells become Plasma cells (memory) that can make Ig quickly when reexposed.
- Any antigen can work: emphasis on pieces of or an entire organism.
- or a toxin/toxoid (tetanus is the theme)
:pencil2:Dose at which we die from tetanus < immune response dose)
- So pt will die, even though immune system doesn't detect/mount response.
- Immunization strategy is to target the toxin, not the bug.
Bad Rxns
Live attenuated
Egg Allergy :fried_egg:
- anaphylaxis is worse than getting the virus.
:no_entry:Yellow Fever
:check:MMRV (can give, no longer egg based)
(changing) Influenza (will no longer be used w/ egg. For the test, be careful and check to see if our flu vaccine is made w/ egg
