Reinfection due to mutation is only a problem in the absence of vaccine. Once you vaccinate an entire community, mutation there stops because transmission stops... as long as you can sequence and identify new, externally introduced mutations to generate boosters using the same mRNA or protein subunit approaches as the original vaccines. Rinse and repeat for other communities. > Anderson Brito, a Brazilian virologist at Yale University, said his lab alone sequenced almost half as many coronavirus genomes as all of Brazil had. While the United States has done genetic sequencing on roughly one in 200 confirmed cases, Brazil sequences about one in 3,000. A year into this, sequencing is a problem that could be entirely solved, even in Brazil, by throwing money at the problem and organizing at the governmental level to hire and train the necessary people. One has to wonder how much damage Bolsonaro has done to the health and welfare of Brazil by discouraging a proactive response from the early days.
