BA.2.86: A New Omicron Subvariant with High Immune Resistance
By [Journalist’s Name]
In a recent announcement on Facebook, Professor Dr. Thira Woratanarat from the Faculty of Medicine Chulalongkorn University shared important findings regarding the BA.2.86 variant of the Omicron strain. These revelations came following a laboratory study conducted by Cao YL from Peking University.
- BA.2.86 displays a unique antigen profile distinct from other Omicron subvariants.
- Unlike other strains, BA.2.86 exhibits higher levels of immune resistance.
- BA.2.86 has shown resistance against all currently approved antibodies.
- Transmission-wise, BA.2.86 lags slightly behind XBB.1.5 in performance.
Cao YL’s study provides academic evidence highlighting the significant divergence of the BA.2.86 variant from its predecessors. It possesses the ability to greatly evade immunity, potentially leading to reinfection even in individuals who have previously contracted different types of the virus or received vaccinations.
However, the lower infectivity of BA.2.86, compared to XBB.1.5, suggests that it may not spread as rapidly as the Omicron BA.1 strain. Consequently, it is imperative not to underestimate the detection rate of BA.2.86, as it surpasses both the Delta (21J) and Omicron BA.2 subvariants in terms of speed (Figure 5: Credit: Fleishon S).
The latest reports from France indicate the presence of BA.2.86 cases. Observations suggest that while EG.5.x is expected to dominate the wave towards the end of this year, BA.2.86 is anticipated to emerge in several months. Given its potential to develop further mutations and increase transmission capabilities, BA.2.86 may become the successor to EG.5.x.
As we navigate through these challenging times, it is of utmost importance to lead a conscious and vigilant life, prioritizing self-protection and adhering to necessary precautions.

Last night, Cao YL of Peking University released the results of a laboratory study.
1. BA.2.86 has a very different antigen to other types of Omicron.
2. BA.2.86 is more immune resistant than other strains. which currently distributes XBB.1.5, EG.5.1 and FL.x
3. BA.2.86 is resistant to all currently approved antibodies.
4. However, comparing the transmission performance, BA.2.86 has such performance a little less than XBB.1.5.
From the results of Cao YL’s study, there is academic evidence to support that this BA.2.86 omicron sublayer is very different from the previous strain. By being able to greatly avoid immunity. Therefore, there is a chance that people who have been infected with other types before will be re-infected. Including people who are immune from vaccines too
However, with the ability to infect As the infectivity is less than XBB.1.5, it is likely that BA.2.86 will not spread rapidly. which is not as fast as the Omicron BA.1
one must not be careless Assessment of the detection rate of BA.2.86 compared to when reported on Delta (21J) and Omicron BA.2, BA.2.86 has a faster detection rate (Figure 5: Credit: Fleishon S)
latest situation France has also reported cases of BA.2.86.
It is estimated that the wave at the end of this year, EG.5.x, will lead the cases, while BA.2.86 will take several months to hatch. which tends to develop further mutations to increase the ability to spread infection However, due to its high immune evasion performance, it is likely to be a successor to EG.5.x.
Should live a conscious life, not careless, always protect yourself.
