Although it's extremely rare for vaccinated people to contract the coronavirus, two new reports illustrate why it's important to get vaccinated, even if the high-risk people around you already have been.
Driving the news: An unvaccinated worker at a Kentucky nursing home caused "breakthrough" infections among vaccinated staff and residents, according to a CDC analysis.
- 18 residents who had been fully vaccinated with the Pfizer vaccine were infected in the outbreak. Six became symptomatic. two were hospitalized and one died.
- That means the Pfizer vaccine ended up being roughly 66% effective at preventing infection and 94% effective at preventing hospitalization and death.
- In a separate analysis, the Chicago health department also identified 22 breakthrough COVID cases among 627 fully vaccinated nursing home residents and staff, including one death.
The big picture: As of April 13, the CDC had tracked just 5,814 reports of "breakthrough" infections, out of 75 million fully vaccinated Americans.
