A survey that checks for COVID-19 antibodies using samples from donated blood is legal, and the randomly selected donors are informed and can opt out, the Central Epidemic Command Center (CECC) said yesterday.
Some blood donors had questioned whether the survey breaches privacy and should require institutional review board approval, Chinese-language media reported yesterday.
Centers for Disease Control (CDC) Deputy Director-General Philip Lo (羅一鈞), who is also the CECC spokesman, said the center on Feb. 20 announced that it has entrusted the Taiwan Blood Services Foundation to work with the CDC to conduct a COVID-19 serology antibody survey.

The survey is conducted based on the Communicable Disease Control Act (傳染病防治法) and the Regulations Governing the Implementation of the Epidemiological Surveillance and Advance-Alert System for Communicable Diseases (傳染病流行疫情監視及預警系統實施辦法), he said.
The foundation would randomly select 7,000 samples from blood donated from January to June this year, and test for antibodies for the nucleocapsid protein of SARS-CoV-2, which could indicate prior infection, Lo said.
The survey is a legitimate part of routine disease monitoring, not a research project, so it does not need approval by an institutional review board, he said.
The survey has an “opt out” mechanism, he said, adding that donors whose blood had been randomly selected would be informed and have the option to opt out of the testing.
Among the 2,400 blood bags donated in January and February that were selected for the survey, 24 donors chose to opt out, Lo said.
The randomly selected blood samples are anonymized and given pseudonyms before they are tested for antibodies, so the results cannot be linked back to individual donors, who also cannot be informed of the result, he said.
As some people questioned why the center did not inform them beforehand, Lo said the donors are informed before their blood is used for the test.
Not all donors of the more than 1 million blood bags expected to be donated in the six months would be informed, he said, adding that the foundation feared that it might slow down the donation process.
The center is grateful to most of the 2,400 blood donors who were informed about the test and agreed to their blood sample being used, he said, adding that the donations make it possible to monitor the infection situation in local communities as it changes.
EXPANSIONIST: China deploys an average of 40 to 50 warships and coast guard vessels daily in the South China Sea, despite pledges not to militarize the region, an official said China is attempting to expand its influence across the First Island Chain and increase pressure on Japan by sending coast guard vessels into waters off of Taiwan under the pretext of maritime negotiations with Japan and the Philippines, a national security official said yesterday. China’s recent actions in the waters east of Taiwan and Japan and the Philippines’ exclusive economic zones (EEZ) are attempts to establish dominance in First Island Chain waters, said the official who declined to be named, adding that this is “expansion disguised as law enforcement.” Framing China’s actions solely as a cross-strait issue is a serious misjudgment that
Through analyzing fossil evidence, a research team at National Taiwan University (NTU) discovered the largest endemic bird to have lived in Taiwan, naming it Pavo miejue, or extinct peafowl (滅絕孔雀). The Mikado pheasant, which is printed on the back of the NT$1,000 bank note, was previously believed to be the biggest endemic bird to Taiwan. The research team’s findings suggest that Pavo miejue lived during the Pleistocene epoch tens of thousands of years ago. It is the first endemic extinct bird species discovered and formally named in Taiwan. The study was coauthored by NTU Institute of Ecology and Evolutionary Biology professor Tsai Cheng-hsiu (蔡政修),
Taiwan Taoyuan International Airport is to suspend its automated Skytrain service connecting Terminal 1 and Terminal 2 starting on July 1 to facilitate connection works for the upcoming Terminal 3, the airport operator said today. Passengers and staff who need to travel between the two terminals after the suspension can instead use the Taoyuan MRT or the airport's 24-hour shuttle bus service, Taoyuan International Airport Corp said. The Taoyuan MRT Airport Line directly links the two terminals, while the shuttle buses are to operate around the clock, the company added. The Skytrain provides free transportation between the airport’s two terminals for travelers and
Taiwan ranked 42nd in terms of peacefulness among 163 countries, down five places from last year, according to this year’s Global Peace Index. With an overall score of 1.751, Taiwan dropped from 37th last year, the report published by the global Institute for Economics and Peace showed. The overall score measures a country’s level of peacefulness using 23 quantitative and qualitative indicators across three domains — ongoing domestic and international conflict, societal safety and security, and militarization. While Taiwan ranked 42nd worldwide, it was listed in ninth place among the 19 Asian-Pacific countries in the report, after New Zealand, Singapore, Japan, Malaysia,
