Brazil started a national campaign against Covid-19 on February 27 using bivalent shots. The first phase will immunize risk groups, including river dwellers and people in the country’s quilombola and indigenous communities, those who are immunocompromised, and people over 70. The second, third and fourth phases will target three different groups, successively: people ages 60 to 69; pregnant and postpartum women; and health professionals. Additionally, immunizers will visit the indigenous communities of the Yanomami territory and the Support House for Indigenous Health in Boa Vista to offer routine immunizations in addition to Covid-19 shots.
