The high transmissibility and changing pathogenicity of the SARS-CoV-2 virus made finding new antivirals and vaccines necessary...

By analyzing a cohort of adolescents that developed myocarditis or pericarditis after vaccination against SARS-CoV-2 vaccination, researchers from Yale University School of Medicine were able to pinpoint the underlying mechanism as an overly active innate immune response to the vaccine that led to broad activation of T cells and natural killer (NK) cells. Myocarditis “has been seen in other vaccine contexts, though is most common after viral infection,” Carrie Lucas told reporters at a press conference announcing the findings.

Even though COVID-19 is transitioning from pandemic to endemic across the world, it will remain first in mind as U.S. lawmakers look to reauthorize the Pandemic and All-Hazards Preparedness Act (PAHPA) this year to ensure the country is better prepared for future threats. With a Sept. 30 deadline for reauthorizing PAHPA, the Senate Health, Education, Labor and Pensions (HELP) Committee has its work cut out for it. But it won’t be starting from scratch. In opening a May 4 hearing on the reauthorization, HELP Chair Bernie Sanders (I-Vt.) said the committee would build on the efforts started last year under then-Chair Patty Murray (D-Wash.) and now-retired Ranking Member Richard Burr (R-N.C.).

Multivalent vaccines that could improve SARS-CoV-2 immunity while also preventing infections by other viruses, such as influenza and respiratory syncytial viruses, constitute an urgent public health need. Currently approved vaccines against SARS-CoV-2 are based solely on the spike protein, which provides limited immunity against variations in spike.

With the COVID-19 public health emergency ending in the U.S. next week, Congress is looking to use the lessons learned from the pandemic to draft a new iteration of the Pandemic and All-Hazards Preparedness Act to ensure the country is better prepared for the next pandemic.
