[자막뉴스] The world’s’emergency’ to the discovery of a mutant virus, the real problem is…

The mutant virus found in the UK is not particularly toxic, but is characterized by high contagion.

The new’GV Group’, which was confirmed in Korea last month, has similar characteristics.

[곽진 / 중앙방역대책본부 환자관리팀장](November 14): There are two things you can think of about where the GV type came from. Possibility of originating from cases of overseas inflow and possibility of originating from mutations occurring in Korea… .]

Viral mutations arise naturally within the viral body as it fights the body’s immune response.

Generally, it is less toxic, but the virus changes itself in the direction of increasing its propagation power.

The real problem is after a large dose of the vaccine.

If vaccination triggers a strong immune response in the body, viral mutations can occur more actively.

Mutations that are far more virulent as well as transmissive can appear, and at worst, mutations that neutralize the vaccine.

[김정기 / 고려대 약학대학 교수 : 백신 접종을 했을 때는 자연 감염보다는 훨씬 더 변이주 발생 가능성이 큽니다. 그래서 앞으로 이와 같은 문제는 계속 발생할 겁니다.]

For this reason, experts believe that research on mutant viruses and improved vaccines after a large dose of the vaccine is more important.

This is why it cannot be easily concluded that the global pandemic of COVID-19 will end even after vaccine development.
