Convergent evolution in nucleocapsid facilitated SARS-CoV-2 adaptation for human infection | Journal of Virology After its emergence, SARS-CoV-2 rapidly adapted to human infection, acquiring numerous mutations across its genome. Many of these mutations remain uncharacterized. This study examines a mutational hot...

Graph showing that prior to 1963 when the measles vaccine was introduced, there were around 300,000-700,000 measles cases per year. Within a few years of the vaccine, the number of cases fell below 20,000/year. There were a blips where cases rose, but shortly after the second vaccine dose was recommended in 1989, annual cases have generally been well below 1,000 cases. In 2000, measles elimination was declared in the US. Now we have sporadic outbreaks that typically spread among unvaccinated people. Chart is from Center for American Progress and is based on CDC data on measles cases.

Vaccines work! As measles cases have recently been reported in Alaska, Georgia, New York, Rhode Island and Texas, it's important to remember that prior to the introduction of the measles vaccine in 1963, measles killed 400-500 people and resulted in ~48,000 hospitalizations per year.
