Before the first COVID-19 vaccine became available, Americans changed their behavior to avoid getting the virus by social distancing and wearing masks. New research from CU Boulder says that change, along with vaccines, saved more than 800,000 lives.

Social distancing allowed 68 percent of Americans to get vaccinated before they contracted the virus, which meant they had much better survival rates than people who contracted the virus before getting vaccinated. Without the behavioral changes, the paper’s authors estimate there would have been 60,000 more deaths each day during the peak of the pandemic.
