About half of all Americans have received at least one dose of a Covid vaccine, based on data released Thursday by the Centers for Disease Control and Prevention, as nationwide infection rates continued their downward trend.

According to data from Johns Hopkins University, New Covid 23,033 cases per day are an average of seven days, 21% lower than a week earlier.

US percentage of the vaccinated population

CDC data shows that 49.9% of the US population received one shot or more, with 40% completing a full vaccination program.

62% of those over the age of 18 are at least partially vaccinated.

Data from a survey published by the Kaiser Family Foundation on Friday suggests that vaccination rates for adults could reach 70% in the next few months. President Joe Biden aims to achieve this goal by July 4th.

In addition to 62% of those who said they had received one or more doses, 4% said they wanted the vaccine as soon as possible. Another 4% of adults – who said they want to “wait and see” before getting a shot – said they have already made an appointment or plan to have the vaccine in the next three months.

The proportion of respondents who said they were “definitely not” vaccinated or only did so when necessary remained constant at around 20% in the last monthly surveys by the Kaiser Foundation.

US vaccine shots administered

According to CDC data, an average of 1.6 million vaccine shots were given per day over the past week.

A handful of states have reported that vaccination incentive programs have increased local immunization rates in some populations following recent declines.

US Covid cases

The 7-day average of daily US Covid cases was 23,033 on Thursday, which is a decrease of more than 6,000 from a week, according to Johns Hopkins.

The number of cases has not been so low since June 2020.

According to a CNBC analysis of the Johns Hopkins data, the average daily caseload in 43 states and the District of Columbia has decreased by 5% or more over the past week.

In some countries outside of the United States, the infection rate is increasing. In Bahrain, for example, there has been record increases in some cases since early May, despite 55% of the population having been vaccinated with at least one dose, according to Our World in Data.

US Covid deaths

The most recent 7-day average of daily deaths in the US from Covid is 667, according to JHU data, although the release of residue data from several states in the past few days obscures the latest trend.

Wednesday’s numbers included 373 Oklahoma-reported deaths announced by the state as part of “ongoing efforts to investigate and clear the backlog of deaths related to COVID-19.”

Maryland added about 500 previously unreported deaths to its total on Thursday.

In some situations, state health departments assign a number of previously unreported cases or deaths to a single day, even if they may have occurred previously. The data can be updated to reflect different dates in the future.

Prior to this week’s reporting problems, the daily death toll had been falling for weeks.
