Dr. Anan Chongkaewwatana, Director of Animal Health and Management Innovation Research Group National Center for Genetic Engineering and Biotechnology (Biotech) post a message on facebook Anan Jongkaewwattana in the case of knowledge of data Covid-19 old breed also cannot be used withDelta speciesYes, people who have been infected before re-infected delta have the virus more likely than those who were not vaccinated, even when vaccinated.AstraZenegra vaccine + Pfizer Complete 2 injections. If infected, still found that the amount of infection is still high.
with the following message: Those who received2 complete vaccines Regardless of the formula, there is still a chance of infection. previous informationdelta seems to say Even if the infection is still there, the amount of virus is not much in the body. tends to be insufficient to continue spreading The belief that people who vaccinate are safe Many countries allow their citizens to take off their masks for various activities. But soon after, we have to campaign to wear masks again.
journal information Nature Medicine just published Collected data on more than 15,000 people tested for COVID with RT-PCR at different times and had vaccination data (AZ and PZ) or previous infections. clearly shows that Knowledge acquired from pre-Delta covid infection It cannot be applied to delta.
While infection with primitive (G) and alpha strains as a result of even a single dose of vaccination or having been infected before. As a result, the amount of virus that can be detected after repeated infection There were fewer than those who were not actually vaccinated. The information is very clear during the alpha epidemic. which is the period when measures to stop using masks But when the Delta outbreak in the country The viral load data in patients has clearly changed. Delta can be measured equally in all groups. no difference whether never vaccinated Received both single-dose and complete vaccinations, or had been infected before. interesting is People who were previously infected with recurrent delta infections also had more viruses than those who were not vaccinated. (But not sure if it is statistically significant.) A Ct of approximately 20-25 is a detectable value of ATK, a value that can culture the virus and, of course, the virus will continue to spread.
Vaccines are a very useful tool for preventing COVID symptoms. But now the vaccine is still not very good at preventing the spread of the virus. After having received 2 injections of vaccination, what can I do? What can’t I do? Must communicate clearly before misunderstanding.
