韓全年人口首次負(fù)增長(zhǎng)
South Korea's population fell year-on-year for the first time in 2020, census data showed Sunday, with a record low number of births getting surpassed by deaths to cause a natural decrease.
1月3日公布的韓國(guó)人口普查數(shù)據(jù)顯示，2020年韓國(guó)首次出現(xiàn)人口負(fù)增長(zhǎng)，死亡人口數(shù)超過(guò)新生人口數(shù)，新生人口數(shù)創(chuàng)歷史新低。
According to the latest census figures released by the Ministry of Interior and Safety, South Korea had 51,829,023 people as of Dec 31, 2020, down 20,838 from the end of 2019.

For 2020, South Korea reported 275,815 births, down 10.65% from the previous year.

But 307,764 people died in 2020, a 3.1% increase from 2019.

The census data also showed a 2.72% increase in the number of households, which now sits at 23,093,108. That is largely attributed to the rise in single-person households.
人口普查數(shù)據(jù)還顯示，由于獨(dú)居人口比例上升，韓國(guó)家庭戶數(shù)增加了2.72%，目前共有2309萬(wàn)3108戶。

>US may cut vaccine doses
美考慮將疫苗劑量減半
The US government is considering giving some people half the dose of Moderna's COVID-19 vaccine in order to speed vaccinations, a federal official said on Sunday.
一位聯(lián)邦政府官員1月3日表示，美國(guó)政府正在考慮將莫德納公司研發(fā)的新冠疫苗每針劑量減半，以加快疫苗接種速度。
Moncef Slaoui, head of Operation Warp Speed, the federal vaccine program, said on CBS' "Face the Nation" that officials were in talks with Moderna and the Food and Drug Administration about the idea.
聯(lián)邦新冠疫苗項(xiàng)目曲速行動(dòng)的負(fù)責(zé)人蒙塞夫?斯拉維在接受美國(guó)哥倫比亞廣播公司《面向全國(guó)》節(jié)目采訪時(shí)表示，聯(lián)邦官員正在與莫德納公司、美國(guó)食品和藥物管理局就上述設(shè)想進(jìn)行溝通。
Moderna's vaccine requires two injections.
莫德納公司的疫苗需要注射兩次。
"We know that for the Moderna vaccine, giving half of the dose to people between the ages of 18 and 55, two doses, half the dose, which means exactly achieving the objective of immunizing double the number of people with the doses we have," Slaoui said. "We know it induces identical immune response" to the full dose, he added.
斯拉維說(shuō)："給18歲到55歲之間的人群注射一半劑量的莫德納疫苗，注射兩劑，這樣可以在現(xiàn)有疫苗存量情況下讓接種人數(shù)增加一倍。"他還說(shuō)，這樣做與注射全部劑量產(chǎn)生的免疫反應(yīng)差不多。
Moderna and the FDA could not immediately be reached for comment.
目前莫德納公司和美國(guó)食品和藥物管理局對(duì)此沒(méi)有發(fā)表評(píng)論。
