Do updated COVID vaccines protect U.S. veterans from severe outcomes?

Data in ~300,000 U.S. veterans show the 2024–2025 COVID-19 booster cut COVID-related ED visits (−29%), hospitalizations (−39%), and deaths (−64%) over six months, with modest yet meaningful absolute gains. In JAMA Psychiatry, a cohort linked risperidone use in dementia to a 28% higher stroke risk, especially in those with prior cardiovascular disease and within the first three months, warranting cautious, time-limited prescribing and monitoring. An article in JAMA Network Open found restless leg syndrome associated with higher subsequent Parkinson’s incidence, supporting RLS as a practical marker for heightened PD risk.
