Dr. Yong opened the study results after injection. “Sinovac-AstraZeneca” vaccine is effective to stimulate immunity as well as 98-99% and infected people. 92.4% of immunity was detected.
Professor Yong Phu Worawan (Dr.Yong) Head of the Center of Specialization in Clinical Virology, Faculty of Medicine, Chulalongkorn University In a Facebook post on Facebook about COVID-19 saying, “Covid vaccine, the study of immunity induced by vaccination in Thailand. After receiving 2 doses of Sinovac vaccine for 1 month and one dose of AstraZeneca vaccination for 1 month, compared with the immunization test in those who recovered from COVID-19 infection over a period of 4. Up to 8 weeks after infection
It was seen that the immune level of the Sinovac vaccine after two injections had a mean immunity level of 85.9 unit / ml, while the immunity after taking a single dose of AstraZeneca was 47.5 compared with the immunity after being infected with 60.9 unit / ml. It also showed that the majority of vaccinated people detected 98-99 percent of their immunity, while those who were infected. 92.4% of immunity was detected.
These data are not indicative of disease prevention efficacy. How much But knowing for sure that even though it is already a disease Immunity levels are also very different, and some people go undetected. Showed that this disease is likely to be again Likewise, current vaccinations It is not yet known what level of immunity will be required. So they can prevent infection But what I know for sure is that if we have an immune system Will be able to reduce the severity of the disease
Vaccine efficacy studies generally compare between vaccinated and placebo or nonvaccinated groups. Then followed up to find out which group had more covid-19 disease, and then compare it as a percentage of the efficacy.
The resulting immunity levels show that both vaccines administered in Thailand Encourage good immunity in the Thai population. How long will the Sinovac and AstraZeneca vaccines last? We are following for a long time. Especially if immunity is greatly reduced It may need to be stimulated with an immune vaccine.
