1) Definition of the groups eligible to receive the bivalent vaccine booster in 2023: The priority groups will be staggered by phases to receive the vaccine according to the availability of immunizers in the country. If the vaccination goal for each group reaches 80% at the same time, the states and municipalities can advance and anticipate the groups. The EPI should intensify communication about the importance of vaccination with the population and with health professionals, especially about the need and relevance of the use of monovalent vaccines for the general population. Communication strategies must be carried out with the integration and support of CONASS, CONASEMS, scientific societies, PAHO, and all areas that have immunization as a common theme. The EPI is reviewing with its legal advisors the ordinance that regulates the Brazilian NITAG.
