Unvaccinated are 5X more likely to catch delta, 11X more likely to die

Beth Mole, reporting for Ars Technica, lays out the facts.

COVID-19 vaccines are largely holding up against the hyper-transmissible delta coronavirus variant, particularly when it comes to preventing severe disease and death, according to three studies published Friday by the Centers for Disease Control and Prevention. […]

In terms of infections, fully vaccinated people were about 11 times less likely to get an infection in the pre-delta period, compared with the unvaccinated (with a 95 percent confidence interval of 7.8 to 15.8). That ratio dropped to 4.6 less likely in the post-delta period (with a 95 percent confidence interval of 2.5 to 8.5).

For hospitalizations prior to delta, fully vaccinated people were 13 times less likely to wind up in the hospital than the unvaccinated (confidence interval of 11.3 to 15.6). After delta, that ratio dropped slightly to 10 times less likely (confidence interval of 8.1 to 13.3). The fully vaccinated were 16.6 times less likely to die of COVID-19 prior to delta (confidence interval of 13.5 to 20.4) and 11.3 times less likely to die after delta (confidence interval of 9.1 to 13.9).

The takeaway from the CDCs data seems clear: Fully vaccinated individuals have a much greater chance of not being impacted by the disease, whether that impact is via infection, hospitalization, or death.

It is so simple. The key to saving lives is everyone getting the vaccine. The key to reopening offices and factories is everyone getting the vaccine. The key to reopening schools is everyone getting the vaccine. The key to keeping bars and restaurants open in cold weather is everyone getting the vaccine. The key to travel and shopping is everyone getting the vaccine. The only way it happens is with a full mandate across the country.
