CDC suppressed COVID-19 vaccine data; federal agencies may remove vaccines from the US market. Clinicians cite a JAMA study: 40% efficacy against hospitalization, 79% against severe outcomes.
The FDA reversed its initial rejection of Moderna's mRNA flu vaccine, agreeing to a normal review after public backlash, while a federal judge invalidated the ACIP advisory committee, leaving the US without functioning vaccine oversight. Moderna's vaccine showed 26.6% greater efficacy than standard flu shots in clinical trials.
FDA reinstates top vaccines regulator ten days after abrupt departure, drawing criticism from public health experts and far-right commentators. Departure was tied to Duchenne muscular dystrophy treatment and COVID-19 vaccine controversies.
The acting director of the CDC delayed publication of a report showing the COVID-19 vaccine cut emergency department visits and hospitalizations for healthy adults last winter by about half. The Department of Health and Human Services did not immediately respond to request for comment.
Moderna shares declined nearly 6% amid extreme options market volatility and a new patent infringement lawsuit from BioNTech. The company faces significant financial challenges with negative earnings and declining revenue growth, while valuation metrics suggest potential overvaluation. Technical indicators point to bearish short-term momentum as the stock approaches key support levels.
Moderna will pay $2.25 billion to settle patent disputes with Arbutus Biopharma and Genevant Sciences over lipid nanoparticle technology used in its COVID-19 vaccine. The settlement removes uncertainty for Moderna's vaccine pipeline and sent the stock surging over 11%. The company expects to end 2026 with $4.5-$5 billion in cash and return to revenue growth by year-end.
A study of nearly 70,000 children found girls exposed to SARS-CoV-2 infection in utero had a 44% increased risk of autism spectrum disorder. The research showed 3.97% of pregnant women had COVID-19 infection, with most cases occurring in the third trimester. No increased risk was observed for boys or for speech/language and motor delays overall.
Moderna has settled with Arbutus and Genevant, facing a potential $1.3 billion liability contingent on Federal Circuit's decision. Multiple institutional investors have increased their stakes in the biotech company during recent quarters.
The FDA agreed to review Moderna's mRNA-based flu vaccine after initially rejecting the application, following a Type A meeting that led to a revised regulatory approach splitting approval pathways by age group.
The FDA has agreed to review Moderna's mRNA influenza vaccine application after initially rejecting it, following modifications by the company. A decision is expected by August 5, 2026.
