which antigenic type of polio occur much & what percentage - give me the answer from levinson
According to Levinson’s Medical Microbiology and Immunology, the most common antigenic type of poliovirus causing infections is Type 1. It accounts for approximately 85% of all polio cases. Type 1 is also the most frequently associated with paralytic polio and epidemics.
herd immunity in polio ??
live attenuated vaccine can provide good herd immunity - as it induce intestinal IgA
WHICH prevent polio virus from replicating in the GI tract and being transmitted to others
herd immunity meaning ?
community immunity
it occurs when a sufficiently large population is immunized so that an unimmunized individual is protected
herd immunity by killed vaccine of polio ?
no
no secretory IgA
can a person be effected by polio repeatedly?
Once a person is infected with a specific serotype of poliovirus or vaccinated against it, they are protected from reinfection by that serotype. However, they could still be infected by a different serotype if they are not immune to it. This is why vaccination against all three serotypes is critical for complete protection.
