Raymond Dutrieuille, 59, a Gulf War veteran with the Marine Corps, received a dose of the Pfizer BioNTech COVID-19 vaccine last week at the Minneapolis VA.

A federal study with support from Duluth researchers has tracked the first two COVID-19 vaccines approved in the U.S. and found that they were 90% effective in real-world conditions and prevented asymptomatic infections.

Clinical trials of the Moderna and Pfizer vaccines looked only at prevention of symptomatic infections, so the latest study of their effectiveness in health care and emergency medical workers is a significant advance, said Dr. Harmony Tyner, an infectious disease specialist at St. Luke's Regional Health Care System in Duluth.

"It protects against asymptomatic infections as well," said Tyner, a co-author of the study published Monday by the U.S. Centers for Disease Control and Prevention. "We know it kept people alive, we know it kept people from dying, but [the clinical trials] didn't test against asymptomatic infections, which is huge."
