BIOL 2900 Lecture Notes - Attenuated Vaccine, Varicella Vaccine, Hpv Vaccines
Document Summary
Artifical: attenuated organisms, killed organisms sub cellular, toxins/toxoids, small fragments and dna vaccine. Attenuation: the virulent parents virus becomes the live attenuated vaccine. Live is the ability to replicate in host cells. Rabies now days are killed bacteria vaccine but when it was made in 1885 it was live. The virus in the vaccine must be alive : to replicate in the vaccinee"s cells. Maternal antibodies: ab from the mom to the newborn before birth. The baby is born with enough ab to fight pathogens. If your rejecting measels vaccine, those ab will kill vaccine and it will kill so that"s why vaccines are given after. Risk for back mutation: keep in mind the risk. Stoped from using attenuated vaccine aganist polio because there"s a chance that it will fight back. The attenuated virus can infect non vaccinated people. Better herd immunity (polio), its vaccinating not only you but those around you as well who are exposed to the bacteria.
