Ajarn Mo Yong posted a Facebook account explaining the evolution and change of virus species.COVID-19 confirmed not related to disease severity The vaccine currently being used is still as effective.
Yesterday (25 Dec), Prof. Yongphu Worawan, head of the Center of Specialization in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Posts and images were posted on Facebook, Yong Poovorawan, about the coronavirus mutation. And vaccines that are currently being used With the details as follows
“COVID-19 Species change according to evolution
Virus causingdiseaseCOVID-19 Beginning in China, there are two strains, the S (Serine) and the L (Leucine) strain, and when the epidemic reaches outside China, the L is better spread and divides the offspring into strains G ( Glycine) and strain V (Valine).
Species G are more evolved. At present, the G strain has spread to the offspring into GH (Histidine) GR (Arginine) and GV (Valine) strains.
Most outbreaks in India are GR strains, but GH strains are less common. No strains have been found in Burma, but are understood. When outbreaks in Burma are mostly GH, because the strains found from Thai people crossed the border from Burma, we detect them as GH strains. Likewise, the species at Samut Sakhon are GH strains.
In addition to species Now talking about the British and South African breeds. Is a genetic change in the area of the spike that protrudes from the virus In particular, the part that will be attached to human cells called the receptor or ACE2 in the 501 amino acid position was originally converted to tyrosine (Y) and understood to make Better adhesion and another change to the enzyme system cuts the spike to allow the virus to enter the cell better. Including studies in epidemiology All details will have to be studied in depth further.
The genetic changes are not related to disease severity and are not related to the immune system. Therefore, the current vaccine remains as effective as before. “
