Peptide-based vaccines deliver tumor-specific antigens to dendritic cells (DCs), triggering tumor-targeted T-cell responses. A peptide-peptide conjugate technology previously developed by researchers from Uppsala University and collaborators enhances this process by using multiple tetanus toxin-derived B-cell epitopes (MTTEs) to facilitate in vivo antigen delivery and DC activation.

Jay Bhattacharya will have his work cut out for him if he wins confirmation as the next director of the U.S. NIH. Besides getting NIH committees back on track to evaluate grant applications and calming the fears of researchers and other staff who have seen about 1,200 colleagues cut from their ranks in recent weeks, Bhattacharya will face the task of rebuilding public trust in the NIH itself.

As U.S. regulatory uncertainty swirls around the vaccine space and health care in general, Vaxcyte Inc. stands poised for a readout of phase II infant data by the end of this quarter with VAX-24, the 24-valent pneumococcal conjugate vaccine (PCV). The San Carlos, Calif.-based firm will offer top-line safety, tolerability, and immunogenicity data, to be followed by top-line data with the booster dose by the end of this year.
