Vaccine for the zombie virus

Yes, though can't we just-

What if there was a zombie virus without an effective vaccine?

I like how you authored your own narrative of a scenario where a zombie vaccine is avaliable and Anti-vaxxers refused to take it😄

Realistically the virus would be contained in less than a week and researchers would get a vaccine without a time limit

"The study suggests that after just 100 days - a little over three months - less than 300 humans would be left alive on the entire planet"

Keep in mind, the U.S is still currently struggling with measles outbreaks and Covid-19. We couldn't even contain the Premium version of the sniffles😄
