President Biden outlined several strategies Tuesday to persuade more Americans to get vaccinated against the coronavirus, including “door-to-door outreach” in targeted communities and stepped-up efforts to get vaccine to primary-care doctors and pediatricians who can encourage adolescents to get shots as they head back to school or get ready for fall sports.

“It’s a year of hard-fought progress. We can’t get complacent now. The best thing you can do to protect yourself and your family and the people you care about the most is get vaccinated,” Biden said in remarks at the White House complex on the federal government’s coronavirus response, after falling shy of his self-imposed July 4 deadline for 70 percent of U.S. adults to have received at least one vaccination shot.

White House press secretary Jen Psaki told reporters Tuesday that by the end of the week, nearly 160 million people in the United States will be fully vaccinated.
