NBA study finds vaccinated people with breakthrough coronavirus infections less likely to infect others - USA TODAY

New research about breakthrough coronavirus infections finds they may be less likely to spread to others because vaccinated people don't shed the virus for as long as the unvaccinated.

The biggest contrast, of course, is that people who are unvaccinated are 5.8 times more likely to get COVID-19 than vaccinated people.

The unvaccinated are 14 times more likely to die from COVID-19 than people who are vaccinated.

A large study by the Centers for Disease Control and Prevention published in October found that unvaccinated people who had had a recent infection were five times more likely to get COVID-19 than those who were fully vaccinated and had not had a prior infection.

A study at the University of California, San Francisco found breakthrough infections among vaccinated people were more commonly associated with slightly more antibody-resistant strains of the coronavirus than those seen in unvaccinated people.

The researchers found that while the viral load was effectively the same between vaccinated and unvaccinated people, there was a difference between symptomatic and asymptomatic breakthrough infections.

And researchers in the United Kingdom found that people with breakthrough infections are two times more likely to be asymptomatic than cases in the unvaccinated
