“Doctor Chalermchai” states that the fourth wave of COVID-19 in Thailand caused by the Omicron virus or “Omicron” Since January 2022 onwards The main viral strain has been identified from subspecies 1 (BA.1) in December 2021 to the onset of subspecies 2 (BA.2) in January 2022 and is now BA.2 strain. almost all of them It is interesting that the injection3rd dose booster vaccine will be able to cope with the virus “Omicron” how much Especially the BA.2 strain, which is the main strain at the moment.
There are data on the effectiveness of vaccine studies in Chiang Mai. During January to March 2022, it was found that two injections did not prevent infection. but reduced mortality by 85%.
The three injections were effective in preventing infection by 34-68% and reducing death by 98%.
interesting is and the level of immunity that rises from the injection3 doses of vaccine How many more than 2 needles? And what are the differences between the first and second subspecies?

After that, blood was collected. to determine the level of immunity at 28 days following the injectionvaccination needle 3 It was found that the level of immunity to BA.1 virus increased from 16.6 to 548.
and per strain BA.2 increased from 11 to 324, it can be said that The third dose of vaccination Modern following two injections of Astrazeneca can stimulate immunity once morest viruses “Omicron” has increased 29-33 times, which is enough to fight the virus Omicron where the difference is Effectiveness once morest the second viral subspecies (BA.2), the current main strain. are 1.7 times less than the first subspecies, therefore it is necessary to follow up on further studies whether How long will the level of immunity for the 3rd vaccination last? which has preliminary information from some countries that Live for regarding 3-6 months.
