In spite of the availability of effective vaccines for COVID-19, testing is still needed to catch any new outbreaks that occur, according to Michael Mina, assistant professor of epidemiology at the Harvard T.H. Chan School of Public Health. “Testing is our eye on the virus,” he wrote in an Ideas piece. “Without testing, we can’t see where it is or where it is going.” He said that it’s “essential that we leverage accurate and highly accessible rapid testing to keep schools, workplaces and travel open in the safest way possible.”
