The South African health department announced on the 25th that a new variant of the new coronavirus has been found in the country, which carries more genetic mutations. Experts warn that it is necessary to pay attention to the possibility that this mutant strain is more infectious and weakens the effectiveness of the existing new crown vaccine.
In order to prevent the introduction of new variants, the United Kingdom, Israel and other countries have announced the suspension of flights from many countries in Africa, including South Africa.
