Saturday-Sunday News Field – Virus Genetics Expert Keep an eye on the omicron strain BA.2.75 that has mutated in more locations than BA.5 and is expected to replace all strains soon. concerned that the current vaccine will be less effective
honorary professor Dr. Wasan Chantrathit, Head of the Medical Genome Center Faculty of Medicine Ramathibodi Hospital Mahidol University states that Omikron BA.5 has 85 mutations from the original strain. and epidemic in many countries including Thailand now In addition to spreading quickly There is still a risk of re-infection. because of immunity from infection will only remember the previous species. When found a mutant It can not destroy the virus, but it is expected that no later than 3 months this infection will calm down. And there will be other species in place.
The omicron BA.2.75 now has more than 100 mutations, more than BA.5 and has been spreading in some countries. From studying the nature of mutant viruses, it was found that they tend to spread quickly. Therefore, there is a possibility that BA.2.75 will soon replace all strains. because it spreads 200% faster than BA.5
even mutated virus may spread quickly and is broad But not that it will cause severe symptoms. Or death is always more and it is believed that Omikron will have symptoms that are not as severe as Delta. But if there are more infections will cause the morbidity rate and more deaths as well
Of concern is the vaccine that is currently produced. originated from the original species Since the outbreak in Wuhan May cause reduced immune efficacy and concern that if BA.2.75 spreads, vaccine efficacy may be reduced by 40-50 percent, more people may be infected.
