Pfizer and Biontech confirmed the effectiveness of their vaccines against the new corona mutations.
According to Arabiya Net, the French News Agency reported that their vaccine is effective against the British and South African mutated versions of the Corona virus.
And laboratory studies have reported that the Pfizer / Biontech vaccine is effective against one of the new strains of the Corona virus, but there is more than one species of the virus.
This means that although the results of these are positive, they cannot be considered conclusive scientific evidence of the effectiveness of the vaccine.
new strains of the virus have been detected in the United Kingdom and South Africa. One of its characteristics is that it is rapidly spreading, and this raised questions about the level of protection provided by the vaccine against it.
The popular opinion is that the vaccine is effective against this new species, but scientists are still seeking evidence to confirm this.
