Don’t Doubt the Data: COVID-19 Statistics

The OU Board of Regents present a resolution to outgoing OU-Tulsa President John Schumann

A look at the latest data shows the effectiveness of getting vaccinated against COVID-19.


  • Unvaccinated individuals make up more than 90% of COVID-19 hospitalizations nationwide.
  • COVID-19 vaccines are safe. Millions of people in the United States have received COVID-19 vaccines under the most intense safety monitoring in U.S. history, and over 4 billion doses have been given worldwide.
  • According to the CDC, unvaccinated individuals who were previously infected are more than twice as likely to be reinfected with COVID-19 than those who were fully vaccinated.

Delta Variant

  • Over 90% of current cases in the United States are caused by the Delta variant.
  •  Delta is more than twice as contagious as previous strains, so it’s more important than ever to get vaccinated to protect you and others from severe disease, hospitalization, and death.

Breakthrough Cases

What is a breakthrough case?

  • Breakthrough cases occur when a fully vaccinated person becomes infected with the COVID-19 virus. COVID-19 vaccines are highly effective and are a critical tool to bring the pandemic under control. However, some fully vaccinated people still get infected with COVID-19.

Does it mean the vaccine doesn’t work? Why should people get the vaccine if you can still get sick?

  • No vaccine is 100% effective to keep you from getting infected. It’s not impossible to still get COVID-19 once you’re vaccinated, but it’s less likely.
  • Even taking breakthrough cases into account, the vaccine still significantly reduces the chances of getting COVID-19.
    • As of Aug. 6, 2021, 0.16% of fully vaccinated individuals in Oklahoma have experienced breakthrough cases.

How severe are breakthrough cases caused by variants?

  • If you get the COVID-19 vaccine, experts say you have a less than 5% chance of contracting a serious case of COVID-19 that could cause hospitalization or death.
