A sandbox is a temporary container.

Originally a term from system security, it refers to an isolated environment in which potentially risky code may be tested without consequence.

Large-scale COVID-19 vaccination sites resemble sandboxes. They do not ask for intent —only for reaction.

Whether biotechnology can offer a reliable safety mechanism remains uncertain. More time is required. Before any result is confirmed, what is first being tested is not the object, but the relation; what is being marked is not the virus, but the position.

It is a political problem — nothing more.

Sandbox，一種暫時性容器，原為系統安全機制術語，用以建立隔離環境，供潛在風險物件進行試驗。大型 COVID-19 疫苗接種場域，宛如 Sandbox，不問意圖，只要求反應。

生技科學能否帶來真確的安全機制尚不可知，仍須時間試煉。在結果確認之前，先被檢測的，不是對象，而是關係；被標示的，不是病毒，而是位置。

是人類的政治問題而已。
