While all of the COVID-19 vaccines being administered in Arizona have been proven safe and effective, experts say, some of the claims of vaccine side effects may not be true. Dr. Lori Fantry, an infectious disease specialist and professor of medicine at the University of Arizona College of Medicine – Tucson, said while the COVID-19 vaccines are known to have common side effects like chills, fatigue, a headache or a sore arm, there are claims circulating that likely aren't legitimately from the vaccine itself.

Researchers at the University of Arizona Health Sciences are trying to find out if vaccinated people can spread the coronavirus. The study, called PreventCOVIDU, is enlisting 12,000 students from more than 20 universities across the country to determine if fully vaccinated people need to continue wearing masks or social distancing. Dr. Elizabeth Connick, chief of the Division of Infectious Diseases at the UArizona College of Medicine – Tucson, is leading the research site.
