Two new polio vaccines developed to eradicate viral disease
New Delhi, Jun 16 (PTI) Scientists have developed two novel oral polio vaccines (nOPVs) that they say will bolster the World Health Organization’s most recent push to finally eradicate the viral disease.
The two nOPVs, recently described in the journal Nature, are made from weakened poliovirus that has been genetically engineered to reduce reversion to dangerous forms of the virus.
“With such variation in vaccination within and between countries, poliovirus has persisted into the 21st century, with sometimes tragic consequences,” said Raul Andino, a professor at the University of California, San Francisco (UCSF) in the US.
