Dr. Anan opens research data It was found that the offspring of BA.2.75, CA.3.1, may have better immune escape properties than that of XBB.
Dr. Anan Jongkaewwattana, a researcher in virology, biotech, posted a message on Facebook Anan Jongkaewwattana regarding the COVID-19 virus.
stating, “It looks like the XBB strain of the virus that is the best at escaping the landscape may soon be knocked out of the championship. Recent data from a research team at Ohio State University suggests that a progeny of BA.2.75, called CA.3.1, may have better immune escape properties than XBB.
The research team used the serum samples of the bivalent booster vaccine subjects to determine the antiviral properties of XBB, regarding 159-199 (compared to a value exceeding 1000 when tested with BA.5). CA.3.1 These high-risk subjects had a CA.3.1 inhibitor of only 62, more than three times lower than XBB.
For the samples received the original booster vaccine, immunity once morest XBB was 42-43 and once morest CA.3.1 was 9, which is equivalent to no immunity at all. Approximately 200 of these groups were immune to BA.5, which was quite evident that the bivalent vaccine actually boosted immunity once morest Omikron.
immunity from people who have been naturally infected with BA.5 The immunity once morest BA.5 was not the same as that of the bivalent immunized group, but the immunity once morest CA.3.1 was not significantly different (regarding 45).
Viruses change very quickly. Come in a direction that escapes the landscape from the original vaccine indefinitely. Vaccine stimulation may require a serious new idea. Because the efficacy of vaccines once morest new viruses is decreasing all the time.”
