US coronavirus infections decline as govt ramps up vaccinations

Coronavirus cases are declining  in US, with seven-day averages moving below 60,000 for the first time in over a month as experts praised the impact of COVID-19 vaccines.

Data from the Centers for Disease Control and Prevention showed that as of April 24, the rolling average was 57,123 cases, and a month-long mini bump was now over.

It comes as the number of people vaccinated continued to rise, though the rate is beginning to taper off as domestic demand slows.

Almost 140 million people have now received one dose or 42% of the whole population.

Writing on Twitter, Ashish Jha, dean of Brown University School of Public Health, said he believed this time the decline would be permanent, "Because in mid-March when the last mini-surge began, 21% of the population had been vaccinated. Today, we're twice that."

He said that 42% with one shot wasn't "enough," but added: "42% close to number at which we should see steady declines in infections. In Israel, once 45% of the population was fully vaccinated, case numbers started to plummet."

Experts are however worried by the vaccination rate, which peaked earlier this month at an average of more than 3 million doses per day and is now down to 2.6 million per day.

Many people who wished to get vaccinated have received jabs, though some access issues persist, particularly among communities of color.

On the other hand, vaccine skepticism remains high among some demographics, including political conservatives.

A government survey last month found the 10 states with the largest share of people who said they definitely or probably won't get vaccinated are all conservative-leaning.
