Covid-19 could be entering a stage of endemicity in India, with low to moderate levels of transmission, according to World Health Organization Chief Scientist Dr Soumya Swaminathan.
In clinical studies, the US pharmaceutical giant says that its vaccine was 85 percent successful in avoiding the medical condition.
India plans to test a combination of its own Covid-19 vaccine, Covaxin, and a prospective intranasal vaccine developed by US researchers, in the hopes of boosting the two vaccines' protective effectiveness against the virus.
According to the NIH, the findings show that the vaccine generates antibodies that successfully neutralize the B.1.1.7 (Alpha) and B.1.617 (Delta) forms of SARS-CoV-2, which were initially discovered in the UK and India, respectively.
The development of the Delta and Delta plus forms of the coronavirus disease (Covid-19) has placed India, and by extension the rest of the world, on high alert once again.
