British ‘Mutant Virus’ … Strong Contagious Features
Viral mutation, caused by fighting the body’s immune response.
Mutant virus … Overall toxicity ↓ Transmitting potency ↑
Stronger immune response after vaccination … Mutation occurs ↑
Research on ‘mutation’ after vaccination and vaccine improvement is important
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](Nov 14): There are two things you can think of about the origin of the GV type. Possibility of originating in cases of foreign influx and possibility of originating in mutations that occurred 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 in the direction of increasing its power to spread.
[김정기 / 고려대 약학대학 교수 : 초기에 감염된 바이러스가 체내에서 완치되는 동안 변이를 일으킨 것입니다. 보통 이런 이야기를 연구자들은 ‘바이러스 피트니스’라고 말하는데요. 숙주에 적응하기 쉬운 바이러스가 선택됐다고 보시면 될 것 같고….]The real problem is after a large dose of vaccine.
If the vaccine triggers a strong immune response in the body, viral mutations can occur more actively.
Much more virulent and transmissible mutations can appear and, in the worst case, 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.
That is why it cannot be easily concluded that the global COVID-19 pandemic will end even after the development of the vaccine.
