To Taiwan | 放下對「群體免疫」的執著 回到對老者的關懷

接種COVID疫苗後死亡的個案在台灣成為社會焦點,我呼籲相關單位暫時放下對「群體免疫」這個目標的追求,先回歸最基本的人性關懷,尊重每個人自己對「打不打疫苗」的判斷和決定。尤其是上了年紀的長者,如果他們有所顧慮,那就應該提醒和協助他們「加強自我防護」。

To Taiwan | 該如何面對無症狀感染者?

很多人說,當然要儘可能找出「無症狀感染者」,才能切斷社區裡的「隱形傳播鏈」。然而,公共衛生的成敗,畢竟不可能建築在「想當然爾」的基礎之上,因此我以美國CDC新近發布的檢測指引和隔離指引為本,對「如何處理無症狀感染者的傳播風險」提出建議,6月14日獲刊在《上報》:https://www.upmedia.mg/news_info.php?SerialNo=115844

To the world | Public health basics are the most important things

Singapore has got locally-transmitted cases down to near zero and topped Bloomberg’s COVID Resilience Ranking in April, 2021. It is worth to notice that only 20% of Singaporeans are fully vaccinated. Please check out this story: https://www.bloomberg.com/graphics/covid-resilience-ranking/


Right after the vaccines became available, many officials and experts kept emphasizing high coverage to achieve herd immunity. I wrote an op-ed article this January to remind that herd immunity may not be the only goal that COVID vaccination could pursue. I believe Singapore’s success helps justify my analysis.

(The op-ed article in South China Morning Post:

I actually wrote another article last August to remind that, as of August 14, Singapore had around 20,000 new confirmed cases after lifting its first lockdown, but Singaporeans have switched to watch hospitalization rate carefully, instead of rushing to the second lockdown, and finally the death toll therefore increased by three only.

(This article in Pacific Daily News:

So, once again, I’d like to say vaccines are a really powerful tool and we need to promote the vaccine rollouts. However, we also need to remember the public health basics are fundamentally the most important things to a successful pandemic response. Just like what the Bloomberg story emphasized, “if there’s one lesson from April, it’s that vaccination alone isn’t ending the pandemic.”
