“Omicron” 3 needle vaccine does not prevent infection low viral load But the sticking point is easier

Dr. Anan Chongkaewwatana, a virologist, posted on Facebook. Anan Jongkaewwattana Disclosure of research results about coronavirus “Omicron” or “Omicron” stating that the results of this research have interesting results. is a comparison of dataOmicron virusattached to the patient

1. Never been vaccinated

2. Get 2 vaccines

3. After the 3rd injection booster shot, the nasal sample was taken for RT-PCR, it was found that the Ct reading (genome copy) in each group was not different. to conclude that The detectable viral load is equally high, but the reality is that the detectable Ct is the amount of viral genetic material. This may be from a virus or cell fragments that the virus has infected and ruptured.

Dr. Anan “This research looked at the relationship between viruses extracted from samples in each infected group, and found that although the Ct values ​​were not different, the virus from the booster group had the live viral load. The viral load (i.e. infecting cells and measuring proliferation in the lab) was less than the other two groups, approximately 1 log, or 10 times, while the virus from the two mRNA vaccination group had undifferentiated viral loads. different from the unvaccinated group. The research team therefore concluded that third stimulation injection May not help prevent infection. but if stuck The virus that will spread to others can be reduced.

Another interesting information from this study is The viral load from a delta infected person with “Omicron” or “Omicron” After receiving 2 doses of vaccination, Delta had higher viral loads in the isolated samples.OmikronFair (10 times as well), but the data in this population group found that delta diffusion It’s slower than the omikron as we’ve seen, indicating that omikron uses a small percentage of the virus to spread. It is much easier to infect than delta, and omikron in this study is still BA.1, which if BA.2, which is more sensitive than BA.1, may be less likely to use the virus to spread the virus. very easy The amount released must be reduced with a mask. The ventilated air will dilute the virus further and the exposure time will be less. I need to help vaccinate.
