COVAX Statement on New Variants of SARS-CoV-2
The emergence of variants of SARS-CoV-2, the virus that causes COVID-19, serve as a powerful reminder that viruses by their very nature mutate, and that the scientific response may need to adapt if they are to remain effective against them. In light of recent news stories regarding the preliminary data on minimal effectiveness of the AstraZeneca/Oxford vaccine at preventing mild to moderate COVID-19 disease caused by the viral variant B.1.351, it is important to note that primary analysis of data from Phase III trials has so far shown – in the context of viral settings without this variant – that the AstraZeneca/Oxford vaccine offers protection against severe disease, hospitalisation and death. This means it is vitally important now to determine the vaccine’s effectiveness when it comes to preventing more severe illness caused by the B.1.351 variant. Additional studies will also allow us to confirm the optimal vaccination schedule and its impact on vaccine efficacy. CEPI has annou...
