The Trump administration is canceling almost $500 million in contracts to develop mRNA vaccines to protect the U.S. against future viral threats. The move thrilled critics of the technology but horrified many public health and biosecurity experts like Jennifer Nuzzo of the Brown Pandemic Center.

Originally launched to track major pandemic outbreaks in the US and around the world, Brown University School of Public Health’s Pandemic Tracker now helps with a wide range of public health efforts. Led by Jennifer Nuzzo, director of the Pandemic Center and professor of epidemiology at SPH, the tracker helps public and policy makers stay on top of disease outbreaks during a time of economic strain and political polarization.

For the first time since the COVID vaccines became available in pharmacies in 2021, the average person in the U.S. can’t count on getting a free annual shot against a disease that has been the main or a contributing cause of death for more than 1.2 million people around the country, including nearly 12,000 to date this year. “COVID’s not done with us,” says Jennifer Nuzzo, an epidemiologist at Brown University. “We have to keep using the tools that we have. It’s not like we get to forget about COVID.”

The federal government announced Wednesday that it is canceling a contract to develop a vaccine to protect people against flu viruses that could cause pandemics, including the bird flu virus that's been spreading among dairy cows in the U.S., citing concerns about the safety of the mRNA technology being used.
