A new study from the Centers for Disease Control and Prevention (CDC) bolsters the argument that unvaccinated individuals are at a much higher risk of experiencing the worst outcomes of COVID-19 than vaccinated individuals.

“These data indicate that authorized vaccines protect against SARS-CoV-2 infection and severe COVID-19, even with increased community transmission of the newly predominant Delta variant,” the CDC report stated.

Between May 1 and July 25, 2021, unvaccinated residents of Los Angeles County, California, were 29.2 times more likely to be hospitalized by COVID-19, the disease caused by the coronavirus, than their fully vaccinated counterparts. Those unvaccinated individuals also accounted for 71.4% of all infections during that time.

About 51.6% of the American population is fully vaccinated. In California, about 55.1% of the population is fully vaccinated while 67.9% have received at least one dose.

“This really is a medical miracle that we were able to take the information that we’ve had over the past two decades and have all of our agencies working together to get us a vaccine in record time,” Dr. Adam Brown, Envision Healthcare’s COVID-19 national task force chair, said on Yahoo Finance Live recently. “But what’s important for folks to recognize is that the safety procedures, the clinical trials, the number of people who were tested with the vaccine, have been followed just like they have been with other types of medications.”

Vaccination has slowed despite scientific data showing that the vaccines make a significant difference in preventing serious illness and death. Unvaccinated individuals cited reasons including distrust of the FDA, concerns over side effects (stemming from misinformation), or personal liberties.
