The United States will begin widely distributing Covid-19 booster shots next
month as new data shows that vaccine protection wanes over time, top U.S.
health officials announced in a joint statement Wednesday.

美國高級衛生官員週三在一份聯合聲明中宣佈，隨著新的數據顯示疫苗保護逐漸減弱，美
國將於下月開始廣泛分發Covid-19第三劑疫苗。

“The available data make very clear that protection against SARS-CoV-2
infection begins to decrease over time following the initial doses of
vaccination, and in association with the dominance of the Delta variant, we
are starting to see evidence of reduced protection against mild and moderate
disease,” according to the statement signed by CDC Director Dr. Rochelle
Walensky, acting FDA Commissioner Dr. Janet Woodcock, White House chief
medical advisor Dr. Anthony Fauci and other U.S. health leaders. “Based on
our latest assessment, the current protection against severe disease,
hospitalization, and death could diminish in the months ahead, especially
among those who are at higher risk or were vaccinated during the earlier
phases of the vaccination rollout.”




As a result, U.S. agencies are preparing to offer booster shots to all
eligible Americans beginning the week of Sept. 20, starting 8 months after
their second dose of Pfizer or Moderna’s vaccines, officials said. While
they said recipients of Johnson & Johnson’s single-shot vaccine will likely
need boosters, they are awaiting more data in the next few weeks before
making a formal recommendation.



The announcement comes ahead of a White House Covid press briefing Wednesday,
where federal health officials are expected to further outline their plan for
boosters. President Joe Biden is expected to speak on the U.S. effort after
the briefing, the White House told reporters Tuesday.

週三，在白宮Covid新聞發佈會之前，預計聯邦衛生官員將進一步概述他們的疫苗計劃
。白宮星期二對記者說，預計拜登總統將在簡報會後就美國的努力發表講話。

The decision to recommend booster shots comes as the public becomes
increasingly concerned about the delta variant and a rise in breakthrough
cases – infections in fully vaccinated individuals. It marks a shift from
previous comments made by U.S. health officials, who said in recent months
that fully vaccinated Americans did not need booster shots at this time.



U.S. officials changed their message on boosters in recent days as cases
continued to rise. Fauci said Thursday that everybody will “likely” need a
booster shot at some point. On Friday, federal officials approved
administering booster shots to Americans with weakened immune systems, which
includes cancer and HIV patients and people who have had organ transplants.

最近幾天，隨著病例的不斷增多，美國官員改變了對第三季疫苗的看法。福西週四說，
每個人都「可能」需要在某個時候打一針。上週五，聯邦官員批准給免疫系統衰弱的
美國人注射第三劑疫苗，其中包括癌症和HIV患者以及接受器官移植的人。

National Institutes of Health Director Dr. Francis Collins, who also signed
on to the statement, said Tuesday that new Covid data, including from Israeli
health officials, caused U.S. health leaders to rethink their position on
vaccine boosters. Israel released new data Monday showing a reduction in the
effectiveness of Pfizer’s Covid vaccine against severe illness among people
65 and older who were fully vaccinated in January or February.



The U.S. is beginning to see similar trends in vaccine effectiveness as well,
Collins said. He said the rise in breakthrough cases may be due to a
combination of the fast-spreading delta variant and Covid vaccine protection
waning over time.

柯林斯說，美國也開始看到類似的疫苗有效性趨勢。他說，突破性病例的增加可能是由於
快速傳播的三角洲變種和Covid疫苗保護逐漸減弱。

“Although right now, it’s still as if our vaccine protection is working
really well,” he said. “But we don’t want to wait until it’s like oh, too
late.”

"雖然現在，我們的疫苗保護仍然運作得非常好，"他說。
"但我們不想等到它就像..哦太遲了。

The move to recommend boosters is likely to spark criticism, especially as a
large portion of the global population has yet to receive even one dose of a
Covid vaccine.

推薦助推器的舉動可能會引發批評，特別是因為全球很大一部分人口甚至還沒有接種一劑
Covid疫苗。

Earlier this month, the World Health Organization asked wealthy nations to
stop the distribution of booster shots until at least the end of September to
give poorer countries the chance to vaccinate their populations with the
first rounds of shots. The request is part of WHO Director-General Tedros
Adhanom Ghebreyesus’ plan to vaccinate 40% of the world by December.


the administration believes it can boost the American population while
ensuring the rest of the world gets vaccinated.

“We believe that is a false choice. We can do both,” Psaki said. “The
United States is far and away the biggest contributor to the global fight
against Covid. We will continue to be the arsenal for vaccines around the
world. We also have enough supply and had long planned enough supply should a
booster be needed for the eligible population.”

Once booster shots are approved, nursing home residents, health-care
providers and the elderly – the first groups to get vaccinated in December
and January – are likely to be prioritized to get extra shots, Collins said
Tuesday. He said “ideally” people should stick with the same manufacturer
they got their first two doses from.

“But if for some reason you don’t have access to it, well, then get the
other one,” he said. “Again, I’d feel more comfortable as a scientist
fixing our plans on real data, and that means sticking to the same kind of
vaccine that you got to begin with.”

在週二的白宮新聞發佈會上，新聞秘書JenPsaki說，政府相信它可以增加美國人口，同時
確保世界其他地區接種疫苗。
