Despite reports of weaknesses in AstraZeneca’s CoV vaccine, the World Health Organization (WHO) and experts recommend its continued use. Initial studies from South Africa showed significantly less efficacy in preventing relatively mild symptoms of the disease, Alejandro Cravioto, chairman of an expert panel advising the WHO, said today in Geneva. But there is no evidence that the vaccine does not protect against severe courses of covid-19, he said.
Even where the viral variant occurs, therefore, there is no reason not to use the vaccine, Cravioto said. WHO concurred with the recommendation. The Independent Expert Panel on Vaccination (SAGE) consists of 26 scientists. It reviews studies and data on all vaccines and then makes a recommendation on whether and how to use them. There is already a recommendation for the CoV vaccines from Biontech and Pfizer, as well as Moderna.
WHO vaccine specialist Kate O’Brien said it is common for all vaccines to be less effective in relatively mild courses of disease than in severe courses. “It is plausible to expect this vaccine to be effective against severe courses of disease,” she said. In addition, the T-cell response, which is important for an immune response, is strong, she said.
