Despite Safety Concerns, FDA Approves Moderna’s mRNA Flu Shot
On Aug. 5, 2026, the U.S. Food and Drug Administration (FDA) approved Moderna’s seasonal flu shot, mFLUSIVA (mRNA-1010), making it the first messenger RNA platform for seasonal influenza in the United States. The decision permits health care providers to use mRNA technology for annual influenza vaccination in eligible age groups.1 FDA regulators approved mFLUSIVA to […]
Live Experimental Pneumonic Plague Vaccines Being Developed After Repeated Attempts
University of Texas Medical Branch (UTMB) researchers have developed live attenuated experimental pneumonic plague vaccines that, according to a July 28, 2026 press release, fully protected mice in a preclinical study. The findings were published in Science Translational Medicine and, according to UTMB researchers, “challenge decades of assumptions about how immunity to plague works and […]
CDC Just Awarded Pfizer $1.2 Billion for COVID-19 Shots
U.S. federal procurement records published in June 2026 show that the U.S. Centers for Disease Control and Prevention (CDC) awarded Pfizer more than $1.24 billion in contracts for adult and pediatric mRNA COVID-19 shots for fiscal years 2026 and 2027. The contracts, which were published on SAM.gov and contained more money allocated for pediatric COVID […]
Mussel Protein Used to Develop New Vaccine Technology
Scientists in South Korea have developed a new adhesive adjuvant protein-based nanoparticle vaccine technology that they believe may provide longer-lasting immunity with a single injection. According to the researchers in a study published in the journal Biomaterials in 2026, the new approach used bioengineering, gene synthesis and cloning to create a new vaccine technology using […]
“Vaccines” for Honeybees and Shrimp?
Researchers are investigating whether feeding inactivated bacteria to invertebrates such as honeybees and shrimp can act as “vaccines” by causing epigenetic changes that prevent disease, even though invertebrates lack the immune system typically targeted by traditional vaccines.1 The first vaccine for honeybees has received conditional approval from the U.S. Department of Agriculture in 2023 and […]
Scientists Creating mRNA Biologics with Added Aluminum Adjuvant
Scientists at Boston Children’s Hospital in Massachusetts have developed an experimental mRNA biologic technology that they say produced longer-lasting immune responses in animal studies without the use of additional booster shots. The 2026 study was published in Nature Immunology.1 The research looked at a challenge in mRNA technology on how to make protection last longer […]
