Scientists finally crack mystery of rare COVID vaccine blood clots

April 11, 2026
Researchers have uncovered why a rare blood clotting disorder can occur after certain COVID-19 vaccines or adenovirus infections. The immune system can mistakenly target a normal blood protein (PF4) after confusing it with a viral protein. This triggers clotting in extremely rare cases. The breakthrough means vaccines can now be redesigned to avoid this reaction while staying effective.

A new approach to cancer vaccination yields more powerful T cells

May 13, 2026
MIT engineers have developed a new way to amplify the T-cell response to mRNA vaccines — an advance that could lead to much more powerful cancer vaccines and stronger protection against infectious diseases.Most vaccines generate both antibodies and T cells that can target the vaccine antigen by activating antigen-presenting cells, such as dendritic cells. In this study, the researchers boosted the
