Children's National Hospital in Washington, D.C. and the National Institutes of Allergy and Infectious Disease are launching a $40 million study to examine long COVID and multi-system inflammatory syndrome in children.

Why it matters: While kids have been comparatively unscathed by COVID, this is the largest study of its kind aimed at understanding the long-term impacts COVID can have on children when they do have more serious outcomes.

"This study will provide us with a critical missing piece of the puzzle," said Roberta DeBiasi, chief of the division of pediatric infectious diseases at Children's National and lead researcher for this study.

By the numbers: More than 3.6 million children have tested positive for COVID-19 and more than 2,800 cases of MIS-C have been reported in the U.S.

  • Researchers plan to look at information about long COVID's quality of life and social impact, as well as the long-term physical impact of the virus, including on the heart and lungs.
  • They also hope to detail the role genetics play in the duration of the immune response to COVID-19, as well as long COVID and MIS-C.

"A pandemic of the unvaccinated"

Data: Our World in Data; Chart: Will Chase/Axios

Coronavirus cases, hospitalizations and deaths are back on the rise in the U.S. as the highly transmissible Delta variant spreads across the country.

The big picture: This is happening almost exclusively to people who aren’t vaccinated, and it’s worse in places where overall vaccination rates are low.

Fully vaccinated U.S. citizens and permanent residents who are currently residing in the United States will be able to enter Canada for nonessential travel without quarantining starting Aug. 9, Canada announced on Monday.

Why it matters: The U.S.-Canada border was closed for nonessential travel beginning in March 2020. With rising vaccination rates and falling case numbers, officials have faced criticism for not moving faster toward a full reopening of the border, the Washington Post reports.
