Question

Analyses have shown that the vaccination rate in the U.S. is markedly lower in states that voted in last November’s election for then-President Donald Trump, who at times downplayed the severity of the pandemic, and now often the number of new cases is higher in the Trump states.

Biden set a goal several months ago of having at least 70% of adults in the U.S. getting at least one vaccine shot by the annual July 4th Independence Day holiday. The U.S., however, fell short of that objective and the number now stands at 68.1%, according to government statistics.

Answer 1

Due to lack of cooperation.

Step-by-step explanation:

The goal can't be achieved due to non-serious behaviour of the people who are the followers of ex-President Donald Trump. If those people can cooperate and get vaccinated so the percentage will be higher than 70 or even 80. Due to lack of cooperation of people is the main reason for the decrease in the percentage of vaccinated people and fail to achieve the goal of 70 % vaccination of adult population.
