Biden prepares to impose a travel ban on South Africa due to the new Corona strain
Reuters news agency reported, in a news item today, that US President Joe Biden intends to impose a travel ban on South Africa to confront the new strain of Corona virus.
3 new studies have raised concerns that the immune response caused by infection or vaccination may be less effective in protecting than the version of the mutated Corona that appeared in South Africa.
According to studies published by the American "Wall Street Journal," the results of laboratory experiments that focus on the body's immune response enhance the need to develop vaccines to counter the virus.
A fourth study conducted by scientists from the companies Pfizer and Biontech showed that their vaccine succeeded in fighting the mutated Corona virus that was discovered in Britain, but this study did not include the mutated strain in South Africa.
And after more than a year since the spread of the epidemic, the discovery of new variants may make the virus more contagious, and prompt researchers to re-study the virus.
The researchers expressed several concerns, including that new strains appear in countries that acquired a large proportion of their citizens an immune response to the previous variants after infection with Corona.
And if this is confirmed through additional research, the results of the studies indicate that victory in the global battle against Corona requires frequent vaccinations and updates to existing vaccines, such as what is done with influenza vaccines every year.
