Experts say we all should expect things to feel easier this year than they did last year, but they still won’t be what most people would consider normal. “My best guess is that it’ll be better than last summer in terms of what we’re doing, but it won’t be back to what it was like in summer 2019,” says Sean O’Leary, MD, MPH, professor of pediatrics and a pediatric infectious diseases specialist at the University of Colorado Anschutz Medical Campus and Children’s Hospital Colorado.

A commentary published last week in the medical journal Pediatrics reviewed a published account of seven cases of myocarditis in teen males following Covid-19 vaccination. The authors concluded that "there are some concerns regarding this case series that might suggest a causal relationship" between the vaccine and myocarditis. "There are some suggestions [the link] may be real, but it's not definitive yet," Dr. Sean O'Leary, a co-author of the commentary, told CNN.

"The good news is, cases continue to fall across the board," said Dr. Sean O'Leary, a pediatric infectious disease specialist at Children's Hospital Colorado and member of the American Academy of Pediatrics.

While the question about the importance of vaccines for little kids is still theoretical, it's still an important one to answer, said Dr. Sean O'Leary, a pediatric infectious disease specialist at Children's Hospital Colorado.
