The Americans will be getting extra protection against Covid-19 while the rest of the world is still waiting for their first vaccine dose. “There are some world leaders who say America should not have a third vaccine shot till other countries get their first dose, but I disagree. We can take care of America and help the world at the same time,” Biden said at the White House.
