As the world continues to grapple with the ongoing COVID-19 pandemic, new questions have emerged about the origin of the virus and whether one of its more pathogenic variants, Delta, may have originated from Pfizer Inc.'s India operations.
Nevertheless, before the program officially closes, the health body did still "strongly encourage everyone who is currently eligible for a first booster and is yet to come forward" and receive one.
A Pfizer executive claims in a video that the company had been exploring ways to "mutate" the coronavirus via "directed evolution" by experimenting on monkeys and the Delta variant, which is more contagious, was discovered in India a month after Pfizer announced its monkey research.
“Promise you won’t tell anyone. The way [the experiment] would work is that we put the virus in monkeys, and we successively cause them to keep infecting each other, and we collect serial samples from them," the Pfizer executive says.
The predicted and actual menstrual cycle lengths before and after vaccination was more significant among women who received two doses within the same menstrual cycle, with an average difference of 3.9 days.
