Instances could improve within the coming weeks “as folks collect for festivals and different occasions,” the C.D.C. has warned. Public well being consultants and officers are urging people who find themselves in danger to get vaccinated earlier than Pleasure occasions start subsequent month.
“For me, the top-line message can be in case you haven’t gotten one dose, get it now, since you do want to attend 4 weeks earlier than you get your second dose,” stated Dr. Jacqueline L. Gerhart, the chief medical officer at Epic Analysis and one of many lead investigators of the N.E.J.M. research.
