据报道，接种了全新冠肺炎疫苗的美国人可以和接种了疫苗的祖父母或朋友聚集在室内，而不用戴口罩或保持距离疾控中心周一宣布了新的指南这些祖父母可以看望和拥抱没有接种疫苗的家庭成员，只要他们没有潜在的疾病，使他们处于新冠肺炎的高风险中。

但是，根据疾控中心的说法，接种疫苗并不意味着你应该去旅行或成群结队地聚集在一起。疾控中心表示，接种疫苗的人仍然应该坚持指导。

疾病预防控制中心表示，完全接种疫苗的人——也就是说，在他们接受第二剂辉瑞或莫德纳后两周疫苗或者单剂量强生疫苗，可以安全地聚集在没有戴口罩或社交距离的室内接种疫苗的朋友或家人周围，也可以拜访没有接种疫苗但患新冠肺炎严重疾病风险较低的单个家庭的朋友或家人。

“如果你和一个朋友或者你和一个家庭成员都接种了疫苗，你可以一起吃饭，”疾控中心主任罗谢尔·瓦伦斯基博士说，他没有戴口罩，也没有保持距离。“你可以去看望你的祖父母，如果你已经接种过疫苗，他们也接种过，”她在白宫的简报中说。

瓦伦斯基说，在一个有些人接种疫苗而有些人没有接种的群体中，建议更加复杂。疾控中心表示，接种疫苗的人在没有口罩和社交距离的情况下与未接种疫苗的人聚集在室内是低风险的，只要未接种疫苗的人患严重疾病的风险低，并且他们家中没有人处于高风险状态。

“这里有一个例子:如果祖父母已经接种了疫苗，他们可以看望他们的女儿和她的家人，即使他们没有接种疫苗，只要女儿和她的家人没有患严重疾病的风险，”她说。

新指南还指出，如果接种疫苗的人接触到新冠肺炎病毒呈阳性且没有任何症状的人，他们不需要隔离或接受检测。

但在公共场合，即使是接种了新冠肺炎疫苗的人，在公共场合、与未接种疫苗的新冠肺炎病高危人群接触时，或者与来自多个家庭的未接种疫苗人群交往时，也应该继续戴口罩并保持距离，即使他们的疾病风险较低。

疾病预防控制中心表示，接种过疫苗的人仍然应该避免聚集在更大的人群中，如果他们表现出任何新冠肺炎症状，应该接受检测。

“我们知道人们想接种疫苗，这样他们就可以回去和他们爱的人一起做他们喜欢的事情，”瓦伦斯基在早些时候的新闻稿中说。

“有一些活动，完全接种疫苗的人现在可以在自己家里的隐私中开始恢复。每个人——即使是接种疫苗的人——在公共场合都应该继续使用所有的缓解策略。随着科学的发展，越来越多的人接种疫苗，我们将继续提供更多的指导，帮助完全接种疫苗的人安全地恢复更多的活动，”她说。

当被问及为什么疾控中心仍建议人们避免旅行时，瓦伦斯基说，数据显示，旅行增加与新冠肺炎病例激增之间存在联系。

“就旅行而言，我们知道的是:每次旅行激增，这个国家的病例就会激增。她说:“我们知道，我们的许多变体都是从国际地方出现的，我们也知道，旅游走廊是一个人们交往频繁的地方。

“在目前这段时间里，我们真的在努力限制旅行，我们希望我们的下一套指南将有更多关于接种疫苗的人能做什么的科学，也许旅行就是其中之一。”

致力于大流行应对的联邦官员表示，他们希望为那些对现在一年的限制感到沮丧的人提供乐观，他们呆在家里，看不到朋友或家人。

2021年3月4日，人们在新冠肺炎雅各布贾维茨会议中心疫苗接种中心早早排队。

但是，与此同时，新冠肺炎病例的数量很高希望人们保持谨慎直到报告的新冠肺炎新病例减少更多的美国人接种了疫苗。

“我们相信这些新建议是我们努力恢复社区日常活动的重要第一步。然而，我们仍然处于一场严重的流行病之中，尽管如此，我们90%以上的人口没有完全接种疫苗，但我们正在努力实现这一目标，”瓦伦斯基说。

“因此，无论是否接种疫苗，每个人都应继续避免大中型聚会以及非必要的旅行，当在公共场所时，应继续戴上合适的口罩，保持身体距离，并遵循其他公共卫生措施来保护自己和他人。”

随着三种授权疫苗的供应增加，美国的疫苗接种量大幅增加。5880万美国人至少接受了一剂疫苗，12%的人被认为是完全接种了疫苗，这意味着他们已经接受了所需剂量的辉瑞或莫德纳疫苗。

Fully vaccinated individuals can socialize without masks, distancing in some cases, CDC says

Americans who have received the full COVID-19 vaccine can gather with vaccinated grandparents or friends indoors without wearing masks or keeping their distance, according tonew CDC guidance announced Monday, and those grandparents can visit with and hug family members that aren't vaccinated as long as they don't have underlying medical conditions that put them at high risk for COVID-19.

But getting the vaccine does not mean you should travel or gather in large groups, according to the CDC, which says vaccinated individuals should still stick to the guidance.

The CDC says individuals who are fully vaccinated -- meaning two weeks after they have received the second dose of the Pfizer or Modernavaccinesor the single dose Johnson & Johnson vaccine -- can safely gather around friends or family who are also vaccinated indoors without masks or social distancing, as well as visit with friends or family from a single household who aren't vaccinated but have a low risk of severe disease from COVID-19.

"If you and a friend or you and a family member are both vaccinated, you can have dinner together," CDC Director Dr. Rochelle Walensky said, without wearing masks and without distancing. "You can visit your grandparents, if you have been vaccinated and they have been too," she said in a White House briefing.

In a group where some individuals are vaccinated and some aren't, Walensky said the recommendations are more complicated. CDC says it is low risk for vaccinated individuals to gather with unvaccinated individuals indoors without masks and social distancing, as long as the people who aren't vaccinated are at low risk of severe disease and no one in their household is at high risk.

"Here's an example: If grandparents have been vaccinated, they can visit their daughter and her family, even if they have not been vaccinated, so long as the daughter and her family are not at risk for severe disease," she said.

The new guidance also says that vaccinated individuals don't need to quarantine or get tested if they come in contact with someone positive for COVID-19 and don't have any symptoms.

But in public, even people who have received the COVID-19 vaccine should continue to wear masks and maintain distance when in public, visiting with people at severe risk for COVID-19 disease who have not been vaccinated, or when socializing with groups of unvaccinated people from multiple households, even if they are at low risk of disease.

The CDC says people who have been vaccinated should still avoid gathering in larger groups and should get tested if they show any symptoms of COVID-19.

"We know that people want to get vaccinated so they can get back to doing the things they enjoy with the people they love," Walensky, said in an earlier news release.

"There are some activities that fully vaccinated people can begin to resume now in the privacy of their own homes. Everyone – even those who are vaccinated – should continue with all mitigation strategies when in public settings. As the science evolves and more people get vaccinated, we will continue to provide more guidance to help fully vaccinated people safely resume more activities," she said.

When asked why CDC is still recommending people avoid travel Walensky said the data shows a connection between increased travel and a surge in new COVID cases.

"In terms of travel, here's what we know: every time that there's a surge in travel, we have a surge in cases in this country. We know that many of our variants have emerged from international places, and we know that the travel corridor is a place where people are mixing a lot," she said.

"We are really trying to restrain travel at this current period of time, and we're hopeful that our next set of guidance will have more science around what vaccinated people can do, perhaps travel being among them."

Federal officials working on the pandemic response have said they want to provide optimism to people frustrated with what's now been a year of restrictions, staying at home, and not being able to see friends or family.

But, at the same time, the number of COVID-19 cases is high and theywant people to remain cautiousuntil fewer new COVID-19 cases are reported andmore Americans are vaccinated.

"We believe these new recommendations are an important first step to our -- in our efforts to resume everyday activities in our communities. However, we remain in the midst of a serious pandemic and, still, over 90% of our population is not fully vaccinated, but we are working hard to get there," Walensky said.

"Therefore, everyone whether vaccinated or not, should continue to avoid medium and large size gatherings, as well as non-essential travel, and when in public spaces, should continue to wear a well-fitted mask, physically distance, and follow other public health measures to protect themselves and others."

Vaccinations are ramping up significantly in the U.S. as the supply of the three authorized vaccines increase. 58.8 million Americans have received at least one dose and 12% are considered fully vaccinated, meaning they've received both required doses of the Pfizer or Moderna vaccines.
