  • Novavax vaccine safety: This week, the CDC published new data in its Morbidity and Mortality Weekly Report (MMWR) affirming the safety of Novavax’s COVID-19 vaccine. Unlike the Pfizer and Moderna vaccines (which use the virus’ genetic information), the Novavax vaccine works by inserting direct copies of the coronavirus spike protein into the body. It was authorized in summer 2022 as a primary series or booster for people who may be unable or unwilling to receive an mRNA vaccine. The CDC found that, among 70,000 Novavax vaccine doses administered between July 2022 and March 2023, no new safety concerns emerged.
  • Insurance coverage for COVID-19 tests: Insurance companies have covered COVID-19 tests very unevenly since the federal health emergency ended this spring. But that could change, if an advisory panel called the U.S. Preventive Services Task Force recommends that the federal government require insurers to cover COVID-19 testing. The panel is exploring this option, reports Sarah Owermohle at STAT News, though it could face legal challenges.
  • Breath test for COVID-19: A couple of weeks ago, I shared a new tool for detecting SARS-CoV-2 particles in the air, developed by researchers at Washington University in St. Louis. The same team has just published another paper, in ACS Sensors, about a similar tool that can diagnose a coronavirus infection using a patient’s breath. This breath test can detect the virus with as few as two breaths and in under 60 seconds, and is close in accuracy to a PCR test. The research team is working to continue testing this device and potentially manufacture it more broadly, according to a press release.
  • COVID-19 spread among white-tailed deer: A recent paper in Nature Communications describes how SARS-CoV-2 has circulated widely among white-tailed deer across the U.S. The research team (which includes scienitsts at the CDC, U.S. Department of Agriculture, and the University of Missouri) collected about 9,000 respiratory samples from deer in 26 states and Washington D.C. between fall 2021 and spring 2022. Hundreds of the samples were positive for SARS-CoV-2, leading the team to study genetic sequences and study how the virus had evolved in this population. The team’s full data are available online.
