One of the essential factors the COVID-19 virus needs to enter a host is a receptor on a human cell — a place where the universally recognized spike protein can latch onto the cell surface, pierce it, disgorge its infectious contents, and replicate.

Without a receptor, there is no replication. Without replication, there is no infection…

More than two years into the pandemic, the virus that causes COVID—SARS-CoV-2—continues to spread worldwide. Testing for the virus and its variants can help limit transmission and inform treatment decisions, and is therefore an important pillar of the public health response.

Now, a team of researchers from

It might not look like much — a plastic box that fits in the hand, with tiny tubes jutting out the top and bottom. Too simple to be cutting edge. Too humble to save so many lives.

But for 20 years, researchers in Robert Prud’homme’s lab have fine-tuned this little box that has revolutionized drug manufacturing, enabling everything…

Dr. Rochelle Walensky, director of the Centers for Disease Control and Prevention (CDC), visited Princeton March 24 to tour the University’s COVID-19 testing laboratory and speak about her public health career during a lecture organized by members of the Class of 2022.

Walensky said there is still a lot of work needed to fight the…

Combining questions about a person’s health with data from smartwatch sensors, a new app developed using research at Princeton University can predict within minutes whether someone is infected with COVID-19.

In the face of a global pandemic, with more than 200 million global infections and 4 million deaths, and despite unprecedented efforts by public health officials, celebrities and influencers to convince everyone to wear masks and get vaccinated as soon possible, the results are mixed.

Now, two Princeton researchers have discovered an…

The allocation of COVID-19 vaccine between countries has thus far tended toward vaccine nationalism, wherein countries stockpile vaccines to prioritize access for their citizenry over equitable vaccine sharing.

The extent of vaccine nationalism, however, may strongly impact global trajectories of COVID-19 case numbers and increase the…

A new survey of Princeton researchers has found strong compliance with the University’s guidelines designed to protect health and safety during the pandemic.

Acknowledging the tremendous efforts of on-campus researchers and the resulting low case counts, the University continues to emphasize continued vigilance and adherence to

COVID-19 has been associated with increases in opioid overdose deaths, which may be in part because the pandemic limited access to buprenorphine, a treatment used for opioid dependency, according to a new study led by Princeton University researchers.

A new technology being developed by Princeton University researchers and alumni could offer a more effective and robust delivery method for COVID-19 vaccines.

Compared to current vaccines, the technology, which relies on a new type of nanoparticle, could introduce five times as much of the vaccine’s active ingredient, mRNA, into…
