Answer 1

Answer:

The discovery that the various antigenic strains of PVs could be grouped into three distinct viral types and the propagation of the PV in vitro led to the development of the vaccines against poliomyelitis: the formalin-inactivated vaccine (IPV) by Jonas Salk (1953) and the live-attenuated vaccines (OPV) by Albert Sabin ...

Answer 2

• In a humanitarian effort, Albert Sabin, the developer of OPV, provides Poliovirus strains to Rotary, which then donates them to the World Health Organization so that they can be distributed to impoverished nations.
• 1979: Rotary commits to immunise six million children in the Philippines against polio over a five-year period.
• Vaccines against poliomyelitis are available (polio). Inactivated poliovirus (IPV) and weakened poliovirus (WPV) are also utilized (OPV).
• The two vaccinations have almost eradicated polio in much of the world, with annual incidences falling from an estimated 350,000 in 1988 to 33 in 2018.
