Biden administration's July 4 vaccination goal is an uphill battle

The United States faces an uphill battle to meet President Joe Biden's goal of vaccinating 70% of adults with at least one dose of Covid-19 vaccine by July 4, according to a CNN analysis. But the administration continues to push ahead with new programs and initiatives, and key players remain hopeful that the goal will be met.   Currently, about 64% of adults in the US have received one dose of Covid-19 vaccine, and an average of about 341,000 adults were added to that total each day over the past week, according to data from the CDC.   But closer to 580,000 adults would need to start vaccination each day going forward to reach Biden's goal by July 4.   Another 16 million adults will need to receive at least one dose to reach 70%. At the current pace of vaccination, the US would hit about 67% of adults on July 4 -- falling short by nearly 7 million adults. The full 70% would be reached around the end of the month.
