Genetics has provided surprising insights into why vaccines used in both the UK and US to combat serious childhood infections can eventually fail. The study, which investigates how bacteria change their disguise to evade the vaccines, has implications for how future vaccines can be made more effective. read more..
Targeted DNA vaccine using an electric pulse
The vaccines of the future against infections, influenza and cancer can be administered using an electrical pulse and a specially produced DNA code, new research suggests. The DNA code programs the body's own cells to produce a super-fast missile defense against the disease, researchers say. read more..

Using federal patient-level quality data, researchers found that "many hospitals treat Whites and minorities equitably" but they noted that since many minorities tend to seek care at hospitals that "perform poorly on common quality score composites, the pay for performance efforts could unintentionally penalize hospitals serving high numbers of minorities. read more..
