The cardiomyositis that is a rare adverse effect of mRNA-based COVID vaccines is due to immune cell activity as a result of increased levels of the chemokines CXCL10 and interferon-γ (IFN-γ). Blocking CXCL10 and IFN-γ could prevent muscle cell damage in cell culture, and cardiomyositis in animal models. The findings, reported in the Dec. 10, 2025, issue of Science Translational Medicine, suggest a way of mitigating the risk of cardiomyositis.
Restricting the recommended use of COVID-19 vaccines in the U.S. wasn’t enough. Now the Children’s Health Defense (CHD) is trying to get the FDA to revoke the BLAs for all versions of the Moderna Inc. and Pfizer Inc.-Biontech SE COVID-19 vaccines.
The U.S. FDA said June 25 it has required updates to the prescribing labels of COVID-19 mRNA vaccines Comirnaty and Spikevax to include new safety information on the risks of myocarditis and pericarditis.
Three years after litigation started over technology used in an mRNA vaccine for COVID-19, Biontech SE is acquiring its adversary, Curevac NV, through an all-stock transaction valued at about $1.25 billion. The amount is lower than the $3 billion in backpay Curevac could win through the lawsuit if a low mid-single-digit royalty were awarded, Evercore ISI analysts Jon Miller and Umer Raffat said. But the legal uncertainty has weighed heavily on the company, which shed 30% of its workforce last July and sold off rights to two of its infectious disease vaccines.
Biontech SE agreed to pay up to nearly $1.26 billion in two separate settlements to resolve royalty disputes with the U.S. NIH and the University of Pennsylvania related to the COVID-19 vaccine the company partnered with Pfizer Inc.
The vagaries of the COVID-19 market and the uncertainties of pandemic fatigue are hitting some biopharma companies in the pocketbook, at least for now. Due to lower-than-expected revenues from its COVID-19 Comirnaty vaccine and antiviral Paxlovid (nirmatrelvir/ritonavir), Pfizer Inc. reduced its 2023 revenue guidance by $9 billion after hours Oct. 13, saying it now anticipates full-year 2023 revenues to range from $58 billion to $61 billion – down from its previous guidance range of $67 billion to $70 billion.
Instead of the bivalent COVID-19 vaccines comprising both the original and omicron BA.4/BA.5 SARS-CoV-2 strains that have been in use in the U.S. since April, the CDC’s Advisory Committee for Immunization Practices voted 13-1 Sept. 12 to recommend the universal use of updated monovalent XBB-containing COVID-19 vaccines as authorized or approved by the FDA.
Biontech SE and Pfizer Inc. filed a petition with the U.S. Patent Trial and Appeal Board for an inter partes review against Moderna Inc., the latest move in an ongoing patent battle over the mRNA technology used to develop COVID-19 vaccines.
Jiangsu Recbio Technology Co. Ltd. released phase II data showing its recombinant two-component COVID-19 vaccine Recov appeared more effective than Comirnaty (tozinameran), the mRNA vaccine developed by Biontech SE and Pfizer Inc., as a booster for users of inactivated vaccines.
