A decade ago, when the firefighter John Burke earned his master’s degree in health care emergency management, he wrote his thesis on pandemic planning. So when the coronavirus hit last spring, Mr. Burke, now the fire chief in Sandwich, Mass., was ready.

“I had my playbook ready to go,” Mr. Burke said.

Testing for the virus was a top priority, so he connected with a private laboratory to ensure that his firefighters, who were transporting coronavirus patients to hospitals, could be regularly tested.

And then he heard that Thermo Fisher Scientific, a Massachusetts company that makes laboratory equipment and materials, was beta testing an air sampler that could help him detect airborne coronavirus particles.

By December, he had installed one in a fire station hallway. The device, about the size of a toaster oven, sucked in ambient air and trapped airborne virus particles — if there were any to be found — in a specialized cartridge. Each afternoon, an employee would remove the cartridge and walk it to the UPS drop box across the street, sending it off for laboratory analysis.

A concert venue. A school bus. An aircraft carrier.

The odds of dying after getting a COVID-19 vaccine are virtually nonexistent.

According to recent data from the Centers For Disease Control and Prevention, you're three times more likely to get struck by lightning.

But you might not know that from looking at your social media feed.

A new NPR analysis finds that articles connecting vaccines and death have been among the most highly engaged with content online this year, going viral in a way that could hinder people's ability to judge the true risk in getting a shot.

The findings also illustrate a broader trend in online misinformation: With social media platforms making more of an effort to take down patently false health claims, bad actors are turning to cherry-picked truths to drive misleading narratives.

AstraZeneca reiterated on Wednesday that its Covid-19 vaccine was very effective at preventing the disease, based on more recent data than was included when the company announced the interim results of its U.S. clinical trial on Monday.

The company said in a news release that its vaccine was 76 percent effective at preventing Covid-19. That is slightly lower than the efficacy number that the company announced earlier this week.
