R&D for long COVID is collapsing
Public and private funding is lacking, scrambling opportunities to develop treatments
cen.acs.org
👋 I cover biotech and pharma for @cenmag.bsky.social from Boston.
Interested in finance & market news, drug development for rare & neglected diseases, & how government/policy shapes biotech. Among other things.
My last cover story was about the sorry state of R&D for #LongCovid pharmaceuticals.

Well that was 2025 in Pharma, and what a year it turned out to be
While the financial landscape didn’t change much for biotechnology and pharmaceutical companies this year, the geopolitical forces shaping the industry did. So did the technological ones. Here is C&EN’s look back at the past year. cen.acs.org/pharmaceutic... #chemsky 🧪
C&EN’s Year in Pharma 2025
In some ways, the pharmaceutical world simply plodded along this year. In others, it was stood on its head

#ACIP Researched did, in fact, perform a randomized controlled trial when the FIRST hep B vaccine was approved in 1982. When an improved hep B was approved in 1986, researchers could not perform a placebo-controlled trial, because it would have been unethical to deny kids an effective vaccine.
