Dr. Anan Chongkaewwatana, virologist, Biotech, NSTDA, posted on Facebook. Anan Jongkaewwattana that during “Omicron” BA.1 epidemic at the beginning of the year, there are still some patients infected with BA.1 without immunization from the vaccine before. allowing researchers to be immune from infection BA.1 naturally, which is considered “Omicron” First, let’s test the ability to stop the virus. “Omicron” New additions include a virus that is a hybrid between BA.1 and Delta (XD).
From the results of the study, it is clear that BA.1 is so different from the original strain that Immunity derived from natural infection cannot be crossed to protect old strains at all, similar to people immunized from older vaccine strains. If not boosted to BA.1, they will be able to escape as well. It was evident that Omikron’s mutation was very abrupt.
interesting is family of viruses WHO called Omicron Similar to BA.2, BA.3 and BA.4/BA.5, we expect it to be closer to BA.1.
original species Which the information says that it is really likely to be so, but the new virus These escaped immunity from BA.1 very quickly. The most obvious was BA.4/BA.5 at the immune level from BA.1.
It’s almost impossible to stop the virus. very close to the original strain, despite the fact that both viruses are grouped as BA or “Omicron” Similarly, the use of Greek letter names as identifiers. Different new species may not be useful or do not do anymore because the information is clear. BA.5 Today, unlike BA.1, it is enough to be called the same family anymore.
covid vaccine A newer version that originally intended to use BA.1 as the primary antigen was correct. FDA to return to readjust BA.5 instead Probably because of this But in the next few months, we may encounter BA.xx, who is out of BA.5 as well. It’s something that’s beyond my expectation.
