RE:RVV will do fine. It's in a niche as a reactive drug(s)
"There's been thousands of deaths attributed to the vaccine in the USA alone so not everyone is willing to take it." It's false statments like this (mainly spread by right wingers in the US) that cause people to be fearful of vaccines. The world would be freaking out if this were true. They pause a vaccine at any hint of trouble.
