BioWorld’s 2022 end-of-year highlights included a toast to the future – of universal vaccines. Even before SARS-CoV-2 vaccines were developed in record time and saved countless lives during the COVID-19 pandemic, vaccines were a rare bright spot in the fight against infectious diseases. Bacteria are becoming multidrug resistant far faster than new classes of antibiotics are being developed, viral spillover events and vector ranges are increasing, and climate change is helping bacteria and fungi alike breach human thermal protections against infections.
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.
Both the FDA and the CDC’s Advisory Committee for Immunization Practices are on the threshold of revising how vaccines are approved and used in the U.S., but whether that opens to a precipice or a new era of stronger evidence and safer use is in the telling of the beholder.
Even though the U.S. CDC is operating on a skeleton crew due to the partial government shutdown, it is updating its immunization schedules to adopt the COVID-19 and chickenpox vaccine recommendations the Advisory Committee on Immunization Practices (ACIP) made at its September meeting.

While the discussions and votes at the past two meetings of the U.S. CDC Advisory Committee for Immunization Practices (ACIP) have generated a lot of controversy and resulted in some states and medical groups issuing their own vaccine schedules, the truth is that the newly reconstituted committee’s recommendations to date are still in line with, or more generous in some instances than, global norms.
GC Biopharma Corp. has filed an IND application with the South Korean Ministry of Food and Drug Safety (MFDS) for a phase I trial of GC-4006A, an mRNA vaccine candidate for COVID-19.
When Robert Kennedy Jr. announced the cancellation of 22 projects related to mRNA vaccines and the end of new investments in that technology, the U.S. Secretary of Health only mentioned their use against respiratory viruses, without referring to other applications. The vaccines whose safety and effectiveness Kennedy is questioning are based on the same molecular principles as cancer vaccines under development. “Continued investment in mRNA technology is essential to fully realize its potential in oncology and ensure that promising strategies like neoantigen-based vaccines reach clinical application.” Kazuhiro Kakimi, professor at the Department of Immunology at Kindai University Faculty of Medicine, told BioWorld.
