Some good news, vaccines help people fight against disease, but for those in Africa it is helping with economic growth, and population. , Tanzania is working closely with Gavi to increase routing vaccine coverage rates, by healthier children means more kids in school, being active , adults getting vaccines means more working, staying active and making more money. this is very positive. living longer is something they should look forward too, it will also help with the spread. :)
