The science academies have been accompanying the annual meetings of the G7 states for more than 15 years. In the run-up to each summit, they address scientific agenda-related issues that require multilateral action.
On 26 November 2021, WHO designated the variant B.1.1.529 a variant of concern, named Omicron, on the advice of WHO's Technical Advisory Group on Virus Evolution (TAG-VE). This decision was based on the evidence presented to the TAG-VE that Omicron has several mutations that may have an impact on how it behaves, for example, on how easily it spreads or the severity of illness it causes. This phase I trial is designed to determine the maximum tolerated dose of the vaccine in patients with early-stage triple-negative breast cancer and to characterize and optimize the body's immune response.
WHO today validated the Sinovac-CoronaVac COVID-19 vaccine for emergency use, giving countries, funders, procuring agencies and communities the assurance that it meets international standards for safety, efficacy and manufacturing. The vaccine is produced by the Beijing-based pharmaceutical company Sinovac. Africa needs at least 20 million doses of the Oxford-AstraZeneca vaccine in the next six weeks to get second doses to all who received a first dose within the 8 - 12-week interval between doses recommended by the World Health Organization (WHO).
