Episode notes

Pfizer says its vaccine against the respiratory virus is safe for pregnant women and effective in helping protect their babies. In a trial results that Pfizer released early last week, the vaccine prevented 69% of severe RSV cases in babies six months and younger. We give other vaccines during pregnancy for this exact same reason. And this is the way I think most babies will end up being protected from RSV.

A respiratory virus called RSV has a lot of kids in critical condition and hospitals overwhelmed. Vox public health reporter and epidemiologist Keren Landman explains newfound hope for a vaccine.

This episode was produced by Victoria Chamberlin, edited by Matt Collette, fact-checked by Laura Bullard, engineered by Paul Robert Mounsey, and hosted by Sean Rameswaram.
