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).

Over a year after the novel coronavirus cemented its grip on the world, much of the conversation surrounding the disease remains simple: how many people died and how many survived?

But researchers at Michigan Medicine say a devastating side effect lurks, underreported, between those extremes - the loss of ability caused by the virus.

Health services across the UK have now administered a total of around 60.6 million vaccines since 8 December, including around 37.9 million people with their first dose (72%) and 22.6 million with both doses (43%), ensuring they have the strongest possible protection against COVID-19 from a second dose.

MSU researcher is studying, raising awareness about the role of sex in the efficacy of vaccines that make use of nanomedicine.

If there's one take-home message for the general public about the coronavirus vaccines approved in the U.S., it's that they are remarkably effective.

The development of antibodies to the COVID-19 virus has been the great long-term hope of ending the pandemic. However, immune system turncoats are also major culprits in severe cases of COVID-19, Yale scientists report in the journal Nature.

These autoantibodies target and react with a person's tissues or organs similar to ones that cause autoimmune diseases such as lupus or rheumatoid arthritis.

Monoclonal antibodies, a COVID-19 treatment given early after coronavirus infection, cut the risk of hospitalization and death by 60% in those most likely to suffer complications of the disease, according to an analysis of UPMC patients who received the medication compared to similar patients who did not.

To stop the current SARS-CoV-2 pandemic, vaccines of high quality, safety, and efficacy are required. Scientists of the Paul-Ehrlich-Institut and the Ludwig Maximilian University at Munich have conceived in the laboratory a novel vector vaccine based on the vesicular stomatitis virus (VSV) with only one part of the spike protein as antigen. They have tested the characteristics of this vaccine in mice.
