世界衛生組織(WHO)專家日前建議,免疫系統較弱及已完成兩劑疫苗接種的人士可接種第三針。港大感染及傳染病中心總監何栢良今日(13日)在港台節目《千禧年代》指,世衛建議針對打完兩針後無抗體反應或免疫力不足的人,而「溝針」第三針接種復必泰的人士,現時數據反映抗體較高。他特別提到早前「溝針」的行會成員葉劉淑儀為例,引述報道指她於接種第三針復必泰後,抗體數字亦由兩位數升至兩萬

港大感染及傳染病中心總監何栢良指,現時針對「溝針」累積不少數據,當中按土耳其數據顯示,「溝針」第三針打復必泰疫苗的人士,其抗體較打科興的高。他指留意到葉劉淑儀「溝針」接種復必泰的報道,指她於接種第三針復必泰後,抗體數字亦由兩位數升至兩萬,與現有數據吻合;而現時全球有數十個國家於過去半年安排特定群組打第三針。他指,現有數據反映接種第三針復必泰或科興有成效及安全。

應於第二針後一個月打第三針何栢良指,世衛的資料主要針對打完兩針後無抗體反應或免疫反應不足的人,他們需要打三針才有足夠免疫反應,不是因打完兩針後抗體下降需要補打第三針。他指,應盡快安排中度或有嚴重免疫系統問題的人盡快打第三針,而現時有相關安排的地區多數於接種第二針後一個月安排打第三針。

世衛亦非泛指全部60歲以上人士需要打第三針,而是針對打滅活疫苗、即科興及國藥疫苗。他估計或有數據反映他們於接種兩針後預防重症保護力不足,不過仍要待世衛公布更多資料

近日機場再有確診個案,何栢良指,政府要考慮加強機場、檢疫酒店及表列處所的防疫措施。他指當局無公布相關特定群組的疫苗接種情況,認為全港仍有100萬人未打針,政府於推動接種疫苗方面可更進取,包括限制進入部份場所或更密自費檢測。
============================================================================================================

抗體數字由兩位數字大幅升上兩萬? 嘩!好似香討好多人咁講,驚唔驚抗體過量呀?

世衛做乜要針對科興及國藥疫苗?

有冇邊個國家係首先打Pfizer/BioNTech等mRNA 疫苗,第二或第三針打國藥/科興?

熱賣及精選



it makes sense if we don't need 4th dose. but the reality is that we will need x doses before things normalize.  it is clear that 2nd dose Pfizer does not generate this number (especially for her age) and the 2 doses sinovac 6 months ago is the reason


香港都清零,囉啲打三針嘅誘因岀嚟啦,狗噏

現實世界唔係一個乜都有 controlled group 嘅實驗室,就算以色列打第三針打到咁快 (三份一人打咗),都唔會話即刻要數據就有數據。因為疫情改善或惡化,唔單止反疫苗注射影響。

只有上帝至有哂所有數據。我大個咗至明當年大學統計學講師呢句說話。專家當然唔係上帝。

不過事實擺在眼前係,以色列已經上咗岸,輕舟已過萬重山!

以色列疫情大幅回落係因為第三針,戴口罩,綠色通行證,定係三樣都有呢?  淨係第三針加強劑幾有用? 呢刻冇人知㗎!

COVID-19 is here to stay, but Israel shows that boosters, masks and vaccine passports can tame the virus

By Middle East correspondent Tom Joyner and Fouad AbuGhosh in Jerusalem

It was the first country to vaccinate, the first to reopen, then the first to widely implement a booster shot.

Now Israel is returning to life close to normal only six weeks after the peak of its worst COVID-19 wave yet.

In mid-September, new infections of the Delta variant had surpassed 10,000 per day and hospitals were groaning under the pressure.

But today, its restaurants are bustling, cinemas and theatres are packed, university lecture halls are full and the major airport is heaving.

Deaths and new infections have plummeted to the single and triple digits, and the country will be welcoming overseas tourists from November 1.

As Australia prepares to begin delivery of a third dose of the vaccine from next week, Israel's turnaround offers a glimpse into a possible future of the pandemic.

So how did the country go from a cautionary tale to a success story in less than two months? The answer lies only partially in vaccines.

Eschewing harsh lockdowns, it instead rolled out a mandatory booster shot to everyone over the age of 12. While masks were compulsory in certain settings, its economy remained defiantly open.

"We were faced with a crucial decision," said Professor Cyrille Cohen of Bar Ilan University, who is also a member of the Israeli government advisory panel on COVID-19 vaccines.

"Should we go back into lockdown? Should we start to think about again closing our businesses and schools? Or should we abide by another solution?"

Without any real-world data on the efficacy of booster shots in the wider community, the Israeli government took a fateful gamble.
In late August, the government approved a third shot as a booster for young adults and teens, and then progressively to categories of adults.

At the time, some scientists spoke against the decision, arguing it lacked clear evidence of any benefit and that the focus should instead be directed towards convincing the unvaccinated to accept their first shots.

But the gamble soon appeared to pay off.
  
As the booster campaign ramped up, new Delta infections, hospitalisations and deaths began to dramatically tumble. More than a third of the Israeli population has now been triple-vaccinated.

Soon, a clear pattern began to emerge among severe cases of the disease and those dying as a result of it — they largely did not include people who had received three shots of the vaccine.

"Almost 95 to 99 per cent of the cases that we saw in the hospital here were those patients who were unvaccinated, or those patients who had not received the booster shot," said Dr David Katz, the director of the COVID-19 unit at Shaare Zedek Medical Centre, a major private hospital in Jerusalem.

Even if Israel's booster campaign was the most important factor in so quickly overcoming the country's summer Delta surge, it's unlikely any type of booster vaccine will be able to sustain that alone, said Ron Balicer, chief innovation officer of major Israeli health fund Clalit Health Services.

A balance of mask mandates, enforcement of the green pass system and widespread testing with a combination of PCR and rapid antigen tests have also played a part.
