The sooner a lay rescuer (bystander) starts cardiopulmonary resuscitation (CPR) on a person having a cardiac arrest at home or in public, up to 10 minutes after the arrest, the better the chances of survival and brain protection, according to an analysis of nearly 200,000 out-of-hospital cardiac arrest cases in the U.S. from 2013 to 2022.

Current guidelines recommend that pregnant people receive a vaccine against respiratory syncytial virus (RSV) -- which typically causes mild, cold-like symptoms in most adults but can be deadly for infants -- during weeks 32-36 of pregnancy. New research suggests that vaccination earlier in that time-frame, closer to 32 weeks, could provide the best protection for newborns against RSV.
