With COVID-19 vaccination pace set to take off, Biden team well on path to hit 100M goal Published Joe Biden says his administration has now purchased enough vaccines to vaccinate all Americans. President Joe Biden announced on Thursday that the federal government has purchased an additional 200 million doses of coronvirus vaccines and said by the summer nearly every American will be able to get vaccinated. WASHINGTON (AP) - It sounded so ambitious at first blush: 100 million vaccination shots in 100 days.
