Biden warned the transformation of Delta is a special concern for the US, when the passing target of 70% of the population before July 4 is at risk of failure.

I was worried that the unfamiliar people could infect the new strain and spread to other unpaid people, President Joe Biden said on July 2.

However, Biden still appreciated the achievements of America.

The number of new cases in the US has increased by 10% in the past week, especially in areas with low immunization rates.

Meanwhile, the vaccination target at least one dose for 70% of the US population before the 4/7 of President Biden stood in front of the risk of failure, when this figure was only 66.8%.

We have moved very close to the goal, Iwan Barankay, the professor of economic and public policy at the Wharton School of the University of Pennsylvania, but added that the US needs to set a target higher than 70% to achieve community immunity.

America, the largest translation area in the world, recorded nearly 34.6 million cases and more than 621,000 deaths.
