看看美国CDC怎么说的
Pfizer’s Covid-19 vaccine gave children 5 and older strong protection against h
ospitalization and death even during the omicron surge that hit youngsters espec
ially hard, U.S. health officials reported Tuesday.
美国健康官员说辉瑞疫苗在避免住院及死亡上，给予5岁以上小孩强大的保护
The CDC reported Tuesday that between April and early January there were nine de
aths related to Covid-19 among vaccinated children ages 5 to 17 — compared to 1
21 deaths among unvaccinated children that age.
Also, the CDC examined pediatric hospitalizations in 10 states from last April t
o the end of January. The vaccine proved 74 percent effective against hospitaliz
ation in 5- to 11-year-olds. Only two vaccinated children were hospitalized comp
ared to 59 unvaccinated children.
CDC在周二的报告中，从去年四月到今年一月底，5-17岁因新冠病毒死亡的小孩中，8例是打
过疫苗的，121例是没打疫苗
另外，CDC检视了去年四月到今年一月底，10个州的小孩住院病例，在5-11岁的小孩中，证
实了疫苗是74%有效。只有2个打过疫苗的小孩住院，有59个未打过的小孩住院。
Tuesday’s study also found that during the time when omicron was predominant, t
he vaccine was 51 percent effective in preventing emergency room or urgent-care
visits by 5- to 11-year-olds. That was fairly similar to the 45 percent effecti
veness for 12- to 15-year-olds who’d gotten their second dose months earlier.
周二的研究也发现，在omicron变流行时，疫苗在5-11岁中，预防重症或急诊是51%有效。这
跟几个月前就接受第二剂的12-15岁的有效率45%差不多。
Unvaccinated 5- to 11-year-olds were 1.3 times more likely to get Covid-19 in Ja
nuary — at the height of the omicron surge — than vaccinated youngsters, accor
ding to new CDC data.
根据CDC的新数据，5-11岁未打疫苗的小孩在一月得到covid-19，也就是omicron高峰时，是
有打疫苗的1.3倍。
CDC是看10个州的数据，不是只有纽约
而且结果证实BNT对于预防重症及住院是有帮助
何说莫比较好 那数据呢？？只看剂量？
这中研院的作法吗？
