Coronavirus is always evolving
The rapid development of several vaccines against the coronavirus gives hope. Nevertheless, these first vaccines must be further developed so that they also protect against corona mutations in the long term. Scientists have now started this work.

Effect of previous vaccines
It is not yet clear how long the protection of the individual vaccines actually works. It is therefore not yet possible to say when the vaccines will have to be further developed. Albert Bourla, head of Pfizer, has already announced that an annual refresh will probably be necessary. The vaccines to date mainly work by stimulating the production of antibodies. The production of T cells is only marginal.

First vaccines in clinical trials
However, some researchers are now focusing on a different way to develop a permanently effective vaccine. With their vaccines, they try to stimulate T cells in particular – that part of the immune response that focuses on finding and eliminating cells that are already infected, not the virus itself, reports ntv.de.
The French company OSE Immunotherapeutics is currently having the first such vaccine clinically tested. “It could protect for several years,” says CEO Alexis Peyroles. These new vaccines will be ready for the market in the coming year at the earliest.
Criticism: Virus could become immune to vaccines
There is also criticism of these super vaccines. Some researchers believe this could mutate the virus to the point where it develops a variant that is immune to any vaccine.
