COVID-19 vaccine could fundamentally change pandemic direction: WHO


GENEVA: A COVID-19 vaccine may be rolled out by March 2021 to the most vulnerable, which could fundamentally change the course of the pandemic, a senior World Health Organization (WHO) official said on Monday.

Bruce Aylward also told the WHO’s annual ministerial assembly that interim results announced earlier in the day from Pfizer Inc’s phase-three vaccine trials were “very positive”. Pfizer Inc PFE.N said on Monday its experimental COVID-19 vaccine was more than 90% effective.
