Hitting latest vaccine milestone, Joe Biden pushes shots for all

The US is set to meet President Joe Biden's latest vaccine goal of administering 200 million Covid-19 shots in his first 100 days in office, as the White House steps up its efforts to inoculate the rest of the public. With more than 50% of adults at least partially vaccinated, Biden on Wednesday will reflect on his efforts to expand vaccine distribution and access in his first three months in the White House.
