EU Wins Vaccine Deal; Doses Go Unused in Germany: Virus Update
The European Commission secured hundreds of millions of additional doses and vowed to speed the clearance of vaccines targeting coronavirus variants. Meantime, fewer than one-tenth of the AstraZeneca Plc vaccine doses delivered to Germany have been administered in the initial days of the rollout. The United Nations is pushing for a worldwide vaccination effort. In the U.K., scientists are set to carry out the world’s first study to deliberately expose volunteers to the new coronavirus to speed research.New York City warned of vaccine shortages stemming from the winter storms that have paralyzed large swaths of the nation.
South scientists Africans had good news to announce to the public on Wednesday, March 3. Several preliminary studies have been carried out at different research institutes across the country to understand the immunity possessed by people who have been infected with the 501Y.V2 variant discovered in South Africa at the end of last year. And according to the first results of this research, it seems that the immune response can subsequently protect them against this variant and other forms of the virus.

What We Know About California COVID Variant B.1.427/B.1.429
Researchers from the University of California, San Francisco, say it should be listed as a "variant of concern."The variant actually comes in two forms, known as B.1.427 and B.1.429, both of which carry a similar, albeit slightly differing, set of genetic mutations—including three that affect the spike protein of the SARS-CoV-2 virus.
This is research carried out by the various laboratories in the country, including the KRISP in Durban, which sequences the various strains of the virus. The first results seem to indicate that people infected with the 501Y.V2 variant would develop resistance, both against this variant which has become the majority among the new cases in South Africa, but also against the older strains identified during the first wave.
After weeks of sharp declines, new Covid-19 cases are beginning to flatten
After six straight weeks of declines in new Covid-19 cases in the US, that number has started to plateau, even as hospitalizations and deaths continue to drop. © Robin Chan/Wicked Local Staff Photo/USA Today Network Vanessa Garnes, head supervisor of Nurse's Heart Medical Staffing based in Columbus, Ohio administers a Covid-19 test on February 21, 2021 The 7-day average of daily new cases was just over 72,000 on Wednesday, according to data from Johns Hopkins University, a total that is relatively unchanged from last Thursday.
Researchers are not yet sure how long this immunity will last, or how these antibodies will react to other variants around the world, as studies are only in their early stages. But this remains "good news for everyone," according to the South African Minister of Health, because such results can help design more effective vaccines against different strains.
South Africa has so far started its vaccination campaign with doses of Johnson & Johnson, after 1 vaccine following disappointing results on mild forms of the disease in a limited clinical trial .
Brazilian, English or South African: what we know and what we do not know about the variants of the coronavirus .
© Copyright 2021, L'Obs The variants of the coronavirus worry but have not delivered all their mysteries. While they appear to be more contagious than the basic virus, doubts remain about their lethality. "The Obs" takes stock of what we know and what we don't yet. Why are variants more contagious than the classical virus? Three variants, English, South African and Brazilian, are considered of particular concern.
