Albert Sabin founded the oral polio vaccine and the vaccine was licensed in 1962.
I think that Dame Jane Goodall vaccinated chimpanzee with the oral polio vaccine because at the time she did not know that vaccination not only does not prevent polio but it actually causes it. I would like to know whether and when she realised this well-documented fact established in humans.
The polio is transmitted through either fecal-oral or oral-oral transmission. In fecal-oral, a non-infected person comes in contact with the stool of someone with the virus. In oral-oral, a non-infected person comes in contact with the respiratory droplets or saliva of an infected person(sneezing...ect.)
It used to be, before a vaccine was developed for it. It was then eradicated down to only 4 countries, all in Africa. People in those countries were opposed to the vaccine. Now it has expanded back out to roughly a dozen countries.
iVDPV= infective vaccine derived poliovirus cVDPV= circulating vaccine derived poliovirus aVDPV= ambiguous vaccine derived poliovirus They are caused by a mutation regaining virulence in the attenuated poliovirus strains (Sabin 1-3) used for the oral poliomyelitis vaccine (OPV). Not sure of the specific difference between regressed strains though.
Vaccines are used to produce immunity by causing the body to generate antibodies. The antibodies can be directed against the organism causeing the illness or against a toxin produced by the organism. Also some allergies are treated by causing the body to develop blocking antibodies. In most cases injections are used to give the treatment. Oral polio vaccine is one exception to this.
Albert Sabin invented the oral live attenuated virus vaccine.
To protect against polio.
