Breakthrough infections were responsible for three-quarters of COVID-19 cases in an outbreak during large public gatherings on Cape Cod, Massachusetts, and nearly all sequenced cases were the Delta variant, researchers found.
Of 469 cases linked to multiple summer events and large summer gatherings in a small town, 346 (74%) occurred in fully vaccinated people, and almost 80% of those cases were symptomatic, reported Catherine Brown, DVM, of the Massachusetts Department of Public Health, and colleagues.

미국은 비상이다. 워싱턴포스트(WP)의 31일 보도에 따르면 미국 질병통제예방센터(CDC)는 최근 매사추세츠주(州)의 조사 결과 코로나19 감염자의 4분의 3이 백신을 완전히 접종받은 사람들이었다는 데이터를 발표했다. 조사 대상자 469명 중 346명이 모더나와 화이자 등 mRNA 백신을 두 번 접종했거나 얀센 백신을 맞아 예방 접종을 완료한 경우였다. 미국 NBC 방송에 따르면 조사 대상자였던 코로나19 감염자 469명은 반스터블 카운티 프로빈스타운에서 열린 대규모 여름 행사에 참석한 사람들이었다. 이들 가운데 표본(133명)을 뽑아 조사한 결과 90%에게서 델타 변이가 확인됐다. 델타 변이로 인한 '돌파감염' 사례다.

*Would booster shot take care of it? I am not so sure about it. Perhaps the vaccines that are available now
is not going to end the pandemic and we may need the better vaccines.

Will the coronavirus vaccine end the pandemic?
Now that we have COVID-19 vaccines, a big question on many Americans’ minds is, will the vaccine end the pandemic?
“The short answer is yes,” says Saju Mathew, M.D., a Piedmont primary care physician. “The long answer is that unless 85% of Americans get the vaccine, we are not even going to get close to ending the pandemic.”
That threshold is critical because that’s how the United States will achieve herd immunity. Note: The herd immunity threshold estimation varies among experts, ranging from 70% to 90%.
“This virus is so contagious and easily transmissible that it’s not going to be enough if only 50% of Americans get vaccinated,” says Dr. Mathew. “Even if I get the vaccine, if I’m around people who didn’t, I can still transmit the virus. The vaccine prevents disease, but it doesn’t necessarily prevent infection.”

Republican Sen. Lindsey Graham of South Carolina announced Monday that he has tested positive for Covid-19 despite being vaccinated and has experienced "flu-like symptoms," but said that he now has only "mild symptoms" and is very glad he had been vaccinated because "without vaccination I am certain I would not feel as well as I do now."

미국 애리조나대 연구팀이 지난해 12월부터 올해 4월까지 화이자·코로나 백신을 접종한 3975명의 의료진을 대상으로 진행한 연구에 따르면, 돌파 감염자는 백신 미접종자 대비 몸 안에서 생성되는 바이러스양이 매우 적었고 감염 지속 시간도 짧았다.
