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.
Gilead Sciences Inc. has identified 3C-like proteinase (3CLpro; Mpro; nsp5) (SARS-CoV-2; COVID-19 virus) inhibitors reported to be useful for the treatment of SARS-CoV-2 infection (COVID-19).
Deficiencies in interferon-stimulated gene 15 (ISG15), a protein that normally regulates the immune response, causes mild but persistent inflammation. However, its absence also provides an unexpected advantage by increasing resistance to viral infections. Inspired by this condition and using mRNA technology, scientists at Columbia University and the Icahn School of Medicine at Mount Sinai have developed a broad-spectrum antiviral platform.

SHEN-211 is a selective 3-chymotrypsin-like protease (3CLpro) inhibitor that can protect against SARS-CoV-2. In previous work, SHEN-211 demonstrated high efficacy in inhibiting 3CLpro (IC50=24 nM) and exhibited broad-spectrum antiviral properties.
As of May 2023, the WHO recommends the use of a monovalent XBB.1 descendent lineage, such as omicron XBB.1.5, as the vaccine antigen for COVID-19 vaccines. However, BA.2.86 and its descendent lineages, such as JN.1, have emerged and rapidly spread worldwide.
