AstraZeneca’s Covid-19 vaccine is safe and effective and should be deployed widely, including in countries where the South African variant of the coronavirus may reduce its efficacy, a World Health Organisation panel said on Wednesday. In interim recommendations on the shot, the Strategic Advisory Group of Experts on Immunisation (SAGE) panel said the vaccine should be given in two doses with an interval of 8 to 12 weeks, and should also be used in people aged 65 and older. Even in countries such as South Africa, where questions have been raised about the AstraZeneca vaccine’s efficacy against a newly-emerged variant of the SARS-CoV-2 coronavirus, “there is no reason not to recommend its use”, SAGE’s chair, Alejandro Cravioto, told a briefing.“We have made a recommendation that even if there is a reduction in the possibility of this vaccine having a full impact in its protection capacity, especially against severe disease, there is no reason not to recommend its use even in countries that have circulation of the variant,” he said
