WHO to expand guidance to vaccine manufacturers and governments on changes needed to combat the mutating virus

World Health Organisation Chief, Tedros Ghebreyesus, says he will meet with the organisation's Strategic Advisory Group of Experts on Immunization, or SAGE today. The meeting will discuss SAGE's recommendations on the use of the Astrazeneca COVID19 vaccine. This comes as a recent study revealed that there was minimum protection in mild to moderate infections of the 501y.v2 strain - which was first identified in South Africa. Ghebreyesus says the organisation will expand guidance to vaccine manufacturers and governments on changes needed to combat the mutating virus.
