Polio Vaccines

Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV). The World Health Organization (WHO) recommends all children be fully vaccinated against polio.

The first successful demonstration of a polio vaccine was by Hilary Koprowski in 1950, with a live attenuated virus which people drank. This vaccine, however, was not approved in the United States. An inactivated polio vaccine, developed a few years later by Jonas Salk, came into use in 1955. Another oral polio vaccine was developed by Albert Sabin and came into commercial use in 1961. It is on the World Health Organization’s List of Essential Medicines, the safest and most effective medicines needed in a health system.

ISRO’s GSAT-30 satellite successfully launched aboard Ariane rocket

India’s “high power” communication satellite GSAT-30, aimed at providing high-quality television, telecommunications and broadcasting services, was successfully launched onboard European Ariane 5 rocket from French Guiana (an overseas French region in South America) today 17, January 2020. GSAT-30 will serve as a replacement for INSAT-4A

The high-throughput 3,357-kg satellite will provide telecommunication services to remote areas and the islands in India. It will service Direct-To-Home (DTH), television uplink, Digital Satellite News Gathering (DSNG) and cellular connectivity. The payload design has been improved to maximise the number of transponders on the satellite body. This will provide improved coverage and will enable Indian broadcasters to air content in the Middle East, Australia and other parts of Asia.

The satellite was launched along with the European Space Company’s telecommunication satellite – Eutelsat Konnect.
