WASHINGTON (AP) â Calling a vaccination âthe most patriotic thing you can do,â President Joe Biden on Sunday mixed the nationâs birthday party with a celebration of freedom from the worst of the pandemic. He tempered the strides against COVID-19 with a warning that the fight against the virus wasn't over. âToday, all across this nation, we can say with confidence: America is coming back together,â Biden declared as he hosted more than 1,000 service members, first responders and other guests for a July Fourth celebration on the South Lawn of the White House. For Biden it was a long-awaited opportunity to highlight the success of the vaccination campaign he championed. The event was the largest yet of his presidency, the clearest indication yet that the U.S. had moved into a new phase of virus response. Shifting from a national emergency to a localized crisis of individual responsibility, the nation also moved from vaccinating Americans to promoting global health.
