‘Dr. Anan’ pointed out that 2 injections of all formulas are not enough to inhibit omikron. Need to stimulate 3 different types of needles
On January 16, 2022, Dr. Anan Chongkaewwatana, a virologist Director of Animal Health and Management Innovation Research Group The National Center for Genetic Engineering and Biotechnology (Biotech) posted on Facebook, saying that the antibody immune level data Inhibition of omikron virus from various vaccine formulations at the Clinical Research Center Faculty of Medicine Siriraj Hospital collected data and evaluated by the research team of Biotech, NSTDA. The results are summarized as shown in the picture below.
1. Vaccine 2 injections, no matter what formulation. Need to be encouraged because it was not enough to suppress the Omikron.
2. The 3rd dose stimulation from the two dose vaccines was able to use mRNA like Pfizer or Moderna, or a viral vector like AZ. There was no statistically significant difference between the full or half-dose doses of both.
3. The use of 3 needles of AZ is not recommended because the stimulation of the 3rd needle of AZ after the body is sufficiently immune to AZ virus and the duration is shorter than 6-12 months, resulting in the immunity is not as high as it should be. It is recommended to stimulate with mRNA.
How much PVNT50 will protect Omikron, no one can tell. But if any formula is greater than 100-120, it should be assumed that it is enough to prevent symptomatic illness at approximately 80% level.
