13 Jun 2022 – Prof. Dr. Yong Phuworawan, Head of the Center specializing in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Post a message via Facebook that Covid 19 Vaccination in children 5-11 years old
The results of the study of the center To vaccinate children aged 5 to 11 years in different vaccination methods. The results can be summarized as follows:
1. Vaccination begins with Sinovaccin followed by Pfizer 2 doses at 1 month were not less effective than Pfizer 2 doses 2 months apart. Specific immunity to immunoglobulin G spikes, but total immunity (globulin G) was higher. Total IgG IgA IgM) in the Pfizer group is higher.
The interval between the crossover regimen is 4 weeks, and the two doses of Pfizer vaccine are 8 weeks apart. landscape will be higher Using the spacing crossover formula is only 1 month. It works faster than the Pfizer treatment, 2 months apart.
3. Children clearly have better immune responses than adults.
4. Two doses of inactivated vaccination in children 5 to 11 years old (Sinovac or Sino Farm), followed by Pfizer at 3 months and older, stimulate very high immunity. as in past adult studies. can protect once morest omicron strains as well
5. Two doses of chinovac first have a higher immunity than two doses of chinofarm as in previous adult studies.
6.In the past, two doses of vaccination, the level of immunity is insufficient. It is necessary to give up to 3 doses, regardless of the type of vaccine. In children, too, two Pfizer doses are not enough. Next, the needle 3 must be stimulated.
7. Inactivated vaccination before This avoided reducing the number of mRNA vaccinations. More mRNA side effects occurred in the second and third doses than the first.
This study waits to be complete. including increased laboratory testing as we do in adult studies. and will continue to be published in internationally recognized journals.
