The U.S. surpassed another milestone in its efforts to vaccinate Americans against the coronavirus. The U.S. Centers for Disease Control and Prevention announced that more than 300 million vaccines doses have so far been administered across the country. Even if the United States meets President Joe Biden’s COVID-19 vaccination goal for first doses by Jul 4, now less than a month away, at least 30 states will not hit the 70 percent mark among their own adult residents. One-dose vaccine coverage hit 63 percent.
