Pfizer isn’t sharing Covid vaccines with researchers for next-gen studies

Researchers studying next-generation vaccines to fight an evolving Covid-19 threat are running into problems getting existing vaccines to use in their research.

Because Pfizer and Moderna hold the patents for the current vaccines, researchers would likely have to get the companies’ permission to use them for research into products like nasal or pan-coronavirus vaccines. Right now, Pfizer isn’t sharing its vaccines for research purposes, a spokesperson confirmed to STAT. Moderna didn’t comment when we asked.
