Public Health officials recommend people get booster doses every four months to maintain immunity against Covid-19.
Dr. Opas Karnkawinpong, director-general of the Department of Disease Control (DDC), stated that the recommendation was based on data indicating that Covid-19 immunity decreases around three to four months after vaccination. He advised people in high-risk groups, such as the elderly, those with underlying health conditions, and pregnant women, to get booster shots every four months to ensure a strong immune system. People who travel abroad or have weakened immunity are advised to do the same.
The DDC’s subcommittee on disease immunity has also approved the 25 micrograms per dose of Moderna vaccine for children aged 6 to 11 years old. Another study confirmed by public health officials found that using Sinovac as the first dose, followed by a Pfizer shot, can boost immunity in children aged 5 to 11.
The subcommittee assures that people can receive other vaccines even if they receive the Covid-19 vaccine on the same day, with the exception of viral vector vaccines, which require a gap because they use live viruses to carry DNA into human cells, and simultaneous injection would reduce vaccine efficiency.
