A study found that only 6% of FDA-approved drugs reflect the US racial and ethnic makeup, with a decline in Black and Hispanic enrollment between 2021 and 2023. The researchers recommend setting diversity goals at preclinical stages and collecting biological samples to understand how people's bodies react to medications.
Researchers identified CXCL10 and IFN-gamma as the major drivers of myocarditis in mRNA-vaccine recipients.

This study uses an analytical model to examine the effects of influenza vaccination on both vaccinated and unvaccinated populations. The results show that vaccination provides significant reductions in disease burden, even when vaccine effectiveness is low, but these benefits are limited in high transmission situations.
A review led by Oregon Health & Science University researchers suggests that the US could save $1 billion a year by dropping adult tetanus and diphtheria booster shots if childhood vaccination rates remain strong. The safety of this approach depends on maintaining high childhood vaccination coverage.
