One year after the World Health Organization declared the coronavirus pandemic, a new study concludes that the British version of COVID-19 is more deadly than previous versions of the virus.
The study, published Wednesday in the British Medical Journal, found that people infected with the British variant were 30% to 100% more likely to die than those infected with other variants, with an average rate of about 64%. .
Since its first discovery last September in the southeast of Britain, this variant has spread to more than 100 countries. Previous studies show that the British variant is much more contagious than the first variant of the virus.
While many countries are trying to vaccinate their populations, US President Joe Biden promised to give the rest of the world any surplus vaccine with a single dose produced by Johnson & Johnson.
Mr Biden made the promise on Wednesday as he announced that the US would buy another 100 million doses of the vaccine. Last month, Mr. Biden pledged $ 4 billion for the World Health Organization's global vaccine distribution program, COVAX. This program provides vaccines with the help of rich countries and distributes them evenly in all other countries of the world.
Meanwhile, a group of American researchers say that those people who have previously been infected with COVID-19 need only one dose of vaccines produced by Pfizer-BioNTech or Moderna, which are taken in two doses. In a letter published Wednesday in the New England Journal of Medicine, 32 scientists from the Icahn School of Medicine at Mount Sinai Hospital in New York said that according to a study involving a small number of people, those who were cured of the corovirus had developed about 10 to 45 times more antibodies after their first dose than a person who had not been previously infected.
More researchers are accepting the theory that the immune system of a person previously infected with COVID-19, creates a stronger and faster defense after vaccination.
