So why are lockdown-free states suddenly doing as well or better than locked-down provinces?
The simple explanation is the rate of vaccination, said Thomas Unnasch, a professor at the University of South Florida who studies diseases.
“It’s starting to get to a point where … the virus is running out of people to infect, so we’re really seeing a decline in the case numbers as a result,” Unnasch said.
In Florida, about 42 per cent of the population has had at least one dose of a vaccine; about 31 per cent are fully vaccinated. In Texas, 50 per cent have one dose, with 37 per cent fully vaccinated.
