There are clusters of unvaccinated people in various parts of the country, and the virus could flourish in those areas. Cnn reports: "Clearly if you have geographic areas that are under-immunized, the virus is going to find them. It will continue to smolder, will continue to make people sick, will continue to send people to the hospital, and will continue to cause deaths," said Dr. William Schaffner, a member of the CDC's Advisory Committee on Immunization Practices. As the virus spreads through these areas with low vaccination rates, it has many chances to change and become potentially even more dangerous."Every time this virus finds a new person, it multiplies. Every time it multiplies, it creates mutations that can spring off, and those mutations can create a variant that is so different that our current vaccine protection might not work or might not work as well," said Schaffner, an infectious disease expert at Vanderbilt University Medical Center. If a variant is resistant, even to some degree, to the vaccine, that "could be problematic even for those who are vaccinated," said Dr. Paul Offit, an infectious disease expert at the University of Pennsylvania."I think we need to fix this. We need to impress on people the importance of vaccination to stop the virus," said Offit, a member of the US Food and Drug Administration's Vaccines and Related Biological Products Advisory Committee. "How many more variants need to be created before this gets their attention?"'
This should be obvious. Of course, if people resist the science of vaccination, if they're stupidly ignorant about it, this will happen--especially in states like Florida, Mississippi, Alabama, Texas where ignorance is celebrated and even encouraged by anti-science legislation. Obviously they're petri dishes for covid. Obviously they're going to cook up viral variants. Obviously more people will die than need to.
Because they didn't get vaccinated.
Because of stupidity and ignorance, encouraged by polluting businesses that don't want you to take science seriously. Because they're greedy. Because they're morally stupid.
