There are 4,000 variants of Corona worldwide, British experts say
British experts have expressed concern over the changing status of Code 19, saying that there are currently 4,000 variants of the corona virus circulating around the world.
That is why, for the first time, the same British experts have started using a combination of AstraZeneca and Pfizer vaccines.
According to British experts, thousands of variants of the changing virus have been reported so far, including the rapidly spreading South African, the British and Brazilian viruses from South London.
British vaccine adviser Nadeem Zhawi has also expressed concern that the vaccines we have may be ineffective in this changing context.
Zhaovi said Pfizer, BioNTech, Moderna, Oxford AstraZeneca and others are working on ways to make their vaccines more effective in preventing the virus from spreading.
In them, the British-modified virus sticks directly to the human ACE-2 receptor, causing it to spread very rapidly. Zhaovi said the UK has the largest collection and database of human genomes (DNA collections) and is now carefully incorporating the coronavirus.
On Thursday morning, the UK administered two different vaccines, the Astrazina and Pfizer vaccines, to different people for the first time, and they are being tested separately to see if they can now be protected from the virus.
This is the first trial of its kind in which mRNA vaccine is being given to patients.
The combination of the two vaccines has previously been shown to be effective against the Ebola virus in Africa.
