So they examined all the placentas of people known to have COVID-19 exposure during pregnancy and placentitis was found in people not fully vaccinated against COVID-19.

Study period pre-vaccination and early delta approx.

Mild maternal disease was associated with severe outcomes. 15/21 patients with stillbirth and COVID-19 placentitis had mild or asymptomatic disease initial COVID-19 infection.

January 1, 2020, through November 4, 2021 was the study period, and CDC published guidance that vaccines were recommended and safe on 11th August 2021.

That means that any women that were vaccinated and protected from placentitis would have been recently vaccinated.

So I am happy that placentitis is prevented by vaccines, but we need more information about how long this protection may last for in the context of waning and variants.

There are more interesting facts in the article about strains and other outcomes.

The dichotomy between COVID-19 initial illness and placenta damage seems to be marked. COVID-19 appears to target placenta heavily.

This is a pathogen that warrants caution and control.

People that have COVID-19 exposure during pregnancy need close monitoring. I would advocate access to PCR testing too.
