Is the vaccine still useful after COVID-19 mutation? Which countries have mutated COVID-19 strains

Whether the vaccine is still used after virus mutation

According to the research, the current mutation degree of COVID-19 is still within the controllable range, which will not seriously affect the severity and infectivity of the disease for the time being, so it will not affect the immune effect of the vaccine on the virus. There is currently no research data indicating that virus mutations have adverse effects on vaccine efficacy.

Which countries have mutated COVID-19

At present, the new mutated COVID-19 mainly comes from the United Kingdom, Brazil, Nigeria, South Africa, India and other places. However, due to the impact of global trade and personnel mobility, the mutated COVID-19 may spread in a short period of time. No matter which country people are in, they should strictly protect themselves, reduce the time they stay in public places, and avoid infection. According to current research results, no adverse effects of mutated viruses on vaccine efficacy have been found, and it is temporarily speculated that the virus is still difficult to infect vaccinated populations after mutation.
