However, after a period of implementation, these agencies found that many children were late for other vaccines and were at risk of diseases other than Covid-19. Therefore, the latest recommendation of the CDC-USA is that it can be injected at the same time and at different sites.

Two types of Covid-19 vaccines are being used for children aged 5-11 years in the group of messenger RNA vaccines. This vaccine is not affected by antibodies circulating in the blood of the vaccinated person.

Dr. Thuy said the Covid-19 vaccines for children aged 5-11 currently used by the Ministry of Health are Pfizer and Moderna.
