When asked about people’s concerns that if mRNA is injected, other types cannot be injected, mRNA must be injected only, and in 2022 will the Pfizer vaccine be enough? Dr. Opas said that vaccinations will be sorted from dead germs Viral vector and mRNA in the past.
By 2022, the Cabinet approved The Ministry of Public Health has purchased 90 million doses of the vaccine, with 30 million doses of Pfizer, which is enough and reassures us that the Astra booster injection or Pfizer, the efficacy of disease prevention and reduction in deaths was no different.
