The Novavax jab is the first to show it is effective against the new variant of the virus discovered in the UK, the BBC's medical editor Fergus Walsh said.

- #44 [macken5+1], 21-01-29 08:25疫苗要一早訂貨,睇中就要落鎚
歐盟遲過英國3個月訂,最近同英國有爭吵
澳洲就訂哂前四隻包括Novavax,不過澳洲唔係要急用.
疫苗製藥商其實在未批准時便生產.
一經批准便立即出貨.
睇黎係有賭博成分 - #45 [muey], 21-01-30 15:08Honestly, I have long been having this confusion. Can anyone enlighten me?
My previously false assumption was that a Covid vaccine would stop our transmission of virus. This has been proved wrong. Covid vaccine is like a any other flu shoys, that it teaches your body to react to fight the virus. For that fighting to kick in, there is a process, meaning it takes time. All knows that during incubation period one can still transmit virus. This is why so many countries having acceleration vaccine inoculation, didn't necessarily see the infected rate dropped. UK's drop was better described as good social distancing practice, and not the vaccine.
Now, my question.
Sinovac in Brazil reported 50.38% effective rate, vs other leading US/EU at 80-90%+. Sinovac also claimed 100% rate with no severe cases. Actually, Sinovac was the only one reporting multiple percentages. Are we comparing apple and orange? Should we be using Sinovac's 100% vs Pfizer/Biontech's 95%?
Remember my corrected vaccine mechanism in the second paragraph above. It is not designed to stop transmission (do correct me here), but to cure Covid, so we never fear life threatening, death rate would just be like flu's. With that, shouldn't we look at Sinovac's 100%, and not the 50.38%.
Whether the person after vaccine inoculated still "got" the virus, that is a ethical question. Why? For vaccine trial, including Phase 3, volunteers are given placebo or actual vaccine to compare results. Whether the volunteer got subsequent infection, that depends multiple environmental factors, community desity, educational background, hygiene, etc. To test, pharmaceutical companies cannot ethically put the any volunteer in danger by placing the volunteer in room full of virus.
Chinese pharm companies are new to the vaccine arena. Perhaps they were not commercially savvy enough and told us everything, all percentages they have.
For us, should we better look at Sinovac at 100% effective rate to compare? - #46 [Kenny], 21-01-30 16:10或者咁講:冇疫苗針100%有効。我自己每年都打流感針,打完一樣有流感,不過中招次數少好多,同冇咁嚴重。Anyway宜家醒目咗,4價先打,3價啋你都儍,流感中招機會少啲。
有師兄講咗以色列:48%人口打咗第一針,但一樣武肝中招到阿媽唔認得,估計疫苗針得66%有効,即係少66%人口中招咁解,仲有33%打完針一樣中招。
好似武肺宜家至少有有3種變種:英國,南非,巴西。宜家啲疫苗只係得一價,應對一種武肺,仲有排搞。
最後修改時間: 2021-01-30 16:13:11 - #47 [muey], 21-01-30 17:36#46, agreed much. A flu shot, no matter 4 valent or 3, only means a better fighting chance against the virus. You will still be infected, sometimes without even knowing, because your body could generate a swift action to neutralize.

#6師兄提供了Sinovac (2nd phase trial), Pfizer (3rd phase trial), 牛津(3rd phase trial) COVID 19 疫苖研究報告。
21720人打完Pfizer 第二劑 vaccine 七天後,有8人中招,但沒有講他們是輕症定重症。所以Pfizer 都可能亦是100%可避免中招covid 19 者變成重症。
Sinovac 現在最爭議是他們所講的50%成效或對重症9X %成效資料是透過傳媒發放,在任何醫學期刋都找不到,所以香港的醫學專家(e.g許樹昌)都等緊他們正式的第三期報告才可給建議。
最後修改時間: 2021-01-30 23:46:11 - #49 [muey], 21-01-31 03:47Read the #6 previously. Sinovac is saying they are gearing towards WHO requirements which do not include publishing at leading medical journals.
All I was saying, reading between lines, and extending thoughts on the ethical issue, it would seem the current medias are comparing apple and orange.
Quite a few typing error in #45 failed to catch - my poor editing. - #50 [hubby], 21-01-31 05:40#49 多謝師兄的啟發性問題。
我又反思,在研究時,如果打了Biotech/Pfizer 22700 中的8 人中了COVID-19 全是輕性病者,「8 」這個數字有沒有足夠的statistical power 可以話「打了Biotech/Pfizer 的疫苗,就算中招都不會有嚴重病徵」?
我估專家好想知道打了Sinovac後,實際有幾多人中招,再仔細覆核Sinovac的結論是否成立。 但Sinovac 現時應未有phase 3 的仔細研究數據發佈。

- #53 [macken5+1], 21-02-01 08:24發達國家幾乎買起哂頂級3隻.
其他國家就無得揀,窮國仲要靠人施捨.
印度同大陸在疫苗外交下填補空缺.
印度目前係疫苗生產大國,製造全世界一半以上疫苗,在供應上佔優勢.
佢隻土炮疫苗供應鄰近國家,中東及巴西等.訂單陸續有來
而死對頭鄰國巴基斯坦要既牛津疫苗都係佢供給.
舊年多人預計印度無法控制疫情而會超越美國升上弟一名.
但怪雞印度扭轉個勢仲可能救返大部分國家 - #54 [浩男123], 21-02-01 14:09印度衛生環境咁差, 點解疫情方面何以控制, 係唔係只是冇公佈?
疫苗用大量人力物力, 分秒必爭咁研發, 成本一定好高, 世上點有免費午餐, 各國政府都係用錢搶買疫苗然後供國民注射, 咁你冇錢當然要遲尐先至有得供應,

- #56 [simpleman], 21-02-01 16:21測試一早做完,數據曾經戲劇性改變,而又遲遲唔出報告,除咗做緊數,真喺諗唔到仲有乜理由。作為醫護要有良心去守穩龍門,睇緊科學數據同結果。
美國護老院確診數字呈下降趨勢
國際 發佈時間 01.02.2021 07:15 最後更新時間 01.02.2021 07:15
在全球疫情最嚴重的美國,逾2613萬人確診新型冠狀病毒,44萬多人不治。美國疾控中心指,至今逾3112萬人已接種疫苗,當中560萬人完成兩劑接種。 聯邦政府數據顯示,接種疫苗計劃開始後,美國的護老院確診數字呈下降趨勢。在1月17日的那一周,美國護老院呈報1.7萬多宗病例,較一個月前的3.2萬多宗減少。專家說,由於護老院病例是由社區感染所引起,所以護老院病例下降的話,相信其他地方確診同樣正下降。養老院院友是首批可接種疫苗的社群,專家認為,數字反映疫苗或正發揮作用,感到樂觀。 不過,一項調查指,近38%美國人指,自己完全不考慮接種或者不確定會否接種。調查又發現,傾向支持民主黨,和年收入逾12萬美元的人,更可能接種疫苗。

印度係民主國家,有反對派政黨.新聞及言論自由.
外國記者隨時篤爆.
而佢每日公佈染疫地區數字.而從最高峰到現時市面情況一定有大差別.
造假難度極高.
世衛有特別方案使窮國有免費疫苗,而印度供應200million劑畀世衛 - #59 [Drhandguns], 21-02-02 08:23>>但怪雞印度扭轉個勢仲可能救返大部分國家
唔可以睇小印度呢個國家, 佢其實同英國嘅聯繫仲好緊密, 話曬都重係英聯邦國家之一。 佢每年都派大量人口去英國讀大學、 讀醫科同做研究, iq唔講得笑。 - #60 [Dlbf], 21-02-02 08:57印度神油,妙不可言。。。你唔好當佢流。。kaka
