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.
For more than 30 years, the U.S. CDC’s Advisory Committee for Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) worked together to harmonize their evidence-based vaccine schedules. Not anymore.
Korea Disease Control and Prevention Agency (KDCA) secured 5.3 million doses of COVID-19 vaccines made by Pfizer Inc./Biontech SE and Moderna Inc., officially including the mRNA-based vaccines in the country’s national immunization program on Aug. 5.
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.
Led by the American Academy of Pediatrics, several medical groups went to court July 7 to force Health and Human Services Secretary Robert Kennedy to restore the CDC’s COVID-19 vaccine recommendations for pregnant women and healthy children ages 6 months to 17 years.
In subpoenaing a former Pfizer Inc. official to appear before the U.S. House Judiciary Committee July 22, Judiciary Chair Jim Jordan, R-Ohio, signaled legislative steps Congress may take in response to allegations that Pfizer slow-walked its COVID-19 vaccine development in 2020 so the trial results wouldn’t have to be disclosed until after the presidential election.
