“I don’t assume there may be convincing sufficient information to say one is best than the opposite,” mentioned Dr. Kristin Moffitt, a doctor at Boston Kids’s Hospital who has handled younger Covid-19 sufferers. “All of us have to acknowledge that to check the 2 head-to-head may be very tough, on condition that they have been studied in a different way.”

Dr. James Conway, a pediatric infectious illness skilled on the College of Wisconsin-Madison. mentioned it was onerous to pinpoint how a lot safety both vaccine would possibly present on condition that they have been examined in opposition to a variant has been outmoded. “You’re sort of enjoying Whac-a-Mole,” he mentioned.
