Ascel Bio has a great story about how vital the flu vaccine was in preventing the deaths of children in Florida this past flu season. The Florida Department of Heath reported that all of the flu deaths in children were in unvaccinated children. They report the vaccine is "completely safe." The full details are at the link.
Ascel Bio is the first organization to make forecasts of diseases like meteorologists make forecasts of hurricanes and other dangerous storms. I am an investor in the company.
