The Ministry of Health expanded, this Monday (20), the recommendation for the second booster dose against Covid-19 for people aged 40 and over, who started the vaccination schedule with Coronavac, Pfizer or AstraZeneca.
The orientation of the Ministry of Health is that the immunization is done with the vaccines of Pfizer, AstraZeneca or Janssen, after the interval of four months of the application of the first booster. With the inclusion of this age group, approximately 9 million people should be vaccinated again.
Those who started the vaccination schedule with a single dose of Janssen should also complement protection. The last recommendation was for the application of a booster dose in people aged 18 years and over, two months after the first application. Now, those aged 18 or over must receive a second booster four months after the first booster.
Those over the age of 40 need a third booster, which should be given after a four-month break from the second booster. In these cases, the recommendation is to use AstraZeneca, Pfizer or Janssen vaccines.
Research carried out by the University of Oxford, in the United Kingdom, commissioned by the Ministry of Health, showed that the heterologous combination for the booster dose, that is, of different vaccines, is more effective. So far, more than 6.6 million Brazilians have taken the second booster dose.
The vaccination schedule by age group will remain in two doses for children aged 5 to 11 years, three doses for people aged 12 to 39 years and four doses for those aged 40 years or older. In the case of adolescents aged 12 to 17 years, only the Coronavac and Pfizer vaccines should be given.
