周三，十几个州通过了一个重要的疫苗里程碑，超过70%的成年人至少接种了一种疫苗冠状病毒疫苗剂量，根据健康数据。

然而，这种情况与少数几个州形成了鲜明的对比，其中大部分位于南部，这些州与成年居民之间的差距还没有达到一半。

成年人首次剂量超过70%门槛的大多数州在东北部，如马萨诸塞州，78.7%;康涅狄格州，75.6%;缅因州，74.3%;新泽西，74.1%。，根据最新健康数据来自美国疾病控制和预防中心。

更多的州和地区正在跨过这个关口，包括纽约，68.1%;弗吉尼亚，67.5%;华盛顿州，69.5%;华盛顿特区，68.4%。，疾控中心的数据显示。

然而，该国其他地区正努力让至少50%的成年人接种部分疫苗。

根据疾控中心的数据，截至周三，阿拉巴马州、路易斯安那州、密西西比州、田纳西州、西弗吉尼亚州和怀俄明州仍有不到50%的成年人接种了至少一剂COVID疫苗。

根据疾控中心的数据，在全国范围内，超过1.62亿18岁以上的美国人，约占总成年人口的62.9%，接种了一剂疫苗。疾控中心的数据显示，超过1.33亿美国成年人，约占整个成年人口的52%，已经完全接种疫苗。

各州一直在争先恐后地增加疫苗需求，这种需求在过去几周有所下降。根据疾控中心的数据，4月11日首次给药剂量达到7天平均330万剂的峰值，但5月28日这一平均值降至110万剂。

一些州已经给予奖励来增加他们的疫苗接种数量，包括彩票百万美元累积奖金,免费大学奖学金青少年居民甚至免费啤酒。

的上升疫苗卫生官员说，这与全国病例、住院和死亡的急剧下降有关。根据疾病预防控制中心的数据，4月初，7天内新报告病例的平均数量约为65，000例，但在过去几周内，平均数量稳步下降，目前为15，622例。

官员们表示，最近的数据可能受到阵亡将士纪念日假期的影响。

70% of adults in 12 states have received at least 1 COVID vaccine dose: CDC

A dozen states passed a major vaccine milestone Wednesday as more than 70% of their adult populations have received at least onecoronavirusvaccine dose, according tohealthdata.

The situation, however, contrasts with a handful of states, most of which are in the South, that have not broken the halfway mark with their adult residents.

A majority of the states that have broken the 70% threshold for first doses among adults are in the Northeast, such as Massachusetts, 78.7%; Connecticut, 75.6%; Maine, 74.3%; and New Jersey, 74.1%., according to thelatest health datafrom the U.S. Centers for Disease Control and Prevention.

More states and territories are on the way to crossing this mark, including New York, 68.1%; Virginia, 67.5%; Washington state, 69.5%; and Washington D.C, 68.4%., the CDC data showed.

Other parts of the country, however, are struggling to reach 50% of adults at least partially vaccinated.

Alabama, Louisiana, Mississippi, Tennessee, West Virginia and Wyoming still have less than 50% of their adult population vaccinated with at least one COVID vaccine dose as of Wednesday, according to the CDC.

Nationwide, more than 162 million Americans over the age of 18, roughly 62.9% of the total adult population, have one vaccine dose, according to the CDC. More than 133 million American adults, roughly 52% of the entire adult population, are fully vaccinated, the CDC data showed.

States have been scrambling to increase vaccine demand, which has waned over the last couple of weeks. First dose administrations reached a peak seven-day average of 3.3 million doses administered on April 11, but that average dropped to 1.1 million on May 28, according to the CDC data.

Some states have given out incentives to increase their vaccination numbers including lotteries withmillion-dollar jackpots,free college scholarshipsfor teen residents and evenfree beers.

The rise invaccineshas been linked to a drastic decline in cases, hospitalizations and deaths across the country, health officials said. At the beginning of April, the seven-day average for new cases reported was around 65,000, but that average has steadily dropped over the last few weeks and is now at 15,622, according to the CDC.

Recent data may have been impacted by the Memorial Day holiday, according to officials.
