Boston Children's scientists create new booster-free mRNA vaccine strategy

In a new study published in Nature Immunology, researchers at Boston Children's Hospital demonstrated that pairing the original COVID-19 mRNA vaccine with an immune system enhancer, known as an adjuvant, extended the duration of the vaccine's protection in mice from a few months up to two years.

AI-created miniproteins show promise for targeting hard-to-treat diseases

G protein-coupled receptors, or GPCRs, sit in the plasma membrane, the boundary that defines the inside and outside of a living cell. They communicate with nearly every physiological process in our bodies - from the ability to see and smell, to sensing of adrenaline, insulin, nutrients and medicines.

Most Americans misunderstand which sexually transmitted infections have preventive vaccines

While data from the Centers for Disease Control and Prevention (CDC) show that the total number of U.S. cases of three sexually transmitted infections (STIs) declined from 2022-24, infection rates remain 13% higher than a decade ago. CDC provisional data show more than 2.2 million U.S. cases of chlamydia, gonorrhea, and syphilis were reported in 2024.

Adjuvanted and high-dose flu vaccines protect older adults equally well

In a large study of 429,595 adults aged 65 years or older, adjuvanted and high-dose influenza vaccines showed no significant difference in protection against PCR-confirmed influenza. The findings support current recommendations that both enhanced vaccines are reasonable options for older adults, while second-season results may further refine the evidence.

New mRNA vaccine strategy dramatically amplifies cancer-fighting T cells

Engineers from the University of Houston, MIT and Harvard have developed a new mRNA-based strategy that dramatically amplifies the T-cell response to vaccines - an advance that could lead to far more powerful cancer vaccines and stronger protection against infectious diseases.
