The Ministry of Health recommended the application of a booster dose of the Covid-19 vaccine for all children between 5 and 11 years old. The guidance, which considers all scientific studies that point to increased protection with the complementary dose, was published this Wednesday (4th) in a Technical Note.
The interval between the second dose and the booster should be from four months. Complementary immunization, for children who took the first and second dose of Pfizer or Coronavac, must be done with Pfizer’s pediatric vaccine.
For the analysis of the booster dose recommendation for this public, among other criteria, an increase in antibody levels was observed after the application of the complementary dose. In the clinical study, the evaluated children showed a six-fold increase in the number of antibodies after the booster dose. In another sub-analysis, the Pfizer vaccine booster proved to be effective against the Omicron variant, with a 36-fold increase in antibody production in this age group.
These results show the importance of completing the vaccination cycle against Covid-19, to ensure that immunizers reach full effectiveness and protect against serious cases and deaths from the disease. Even those who missed the recommended deadline should look for a vaccination post. The Ministry of Health also recommends the simultaneous administration of Covid-19 vaccines with the other immunizers in the vaccination schedule to protect children against other diseases.
