Research facilities and biotechnology firms are striving to develop effective vaccines or drugs against the novel coronavirus, but people must still practice the “new disease prevention lifestyle” to protect themselves, the Central Epidemic Command Center (CECC) reminded the public yesterday as it reported no new cases of COVID-19.
“As there have been no domestic cases reported for many consecutive days [52], local communities in Taiwan are relatively safe, but we still need to rely on the development of vaccines and drugs to effectively control the overall situation,” Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said at the center’s daily news conference in Taipei.
Eight COVID-19 patients remain hospitalized, but 428 people have recovered and been released from isolation, he said.

While disease prevention regulations are to be eased on Sunday, that does not mean doing away with all protective measures before an effective vaccine or medication is developed, Chen said.
The main principles include keeping proper social distance or wearing a mask, frequently washing hands and checking your temperature, and enforcing name registration to keep contact records in places where it is needed, he said.
The center encourages people to visit restaurants and businesses that implement disease prevention measures, he added.
National Health Research Institute (NHRI) president Liang Kung-yee (梁賡義) told the news conference that more than 100 teams around the world are trying to develop a vaccine, and so far 10 candidates have progressed to the clinical trial phases: three types of nucleic acid vaccines, two types of recombinant vaccines, four types of inactivated vaccines and one type of subunit vaccine.
The institute is cooperating with three local biotechnology firms on the development of four vaccines, and Academia Sinica is working with two others on two more vaccines, Liang said.
A subunit vaccine is expected to go into clinical trial phases this autumn at the earliest, he said.
As for the development of antiviral drugs, while the Food and Drug Administration (FDA) last week gave rapid conditional approval to remdesivir, and hydroxychloroquine, a drug used to treat malaria and other diseases, is going through clinical trial, potential drugs are being developed in Taiwan, he said.
The NHRI discovered a wide-effect coronavirus antibody during the 2003 SARS outbreak and is using it to develop a potential treatment for COVID-19, Academia Sinica is developing possible treatments using several protease inhibitors of COVID-19 that it has identified, and a joint research team from the NHRI, the National Defense Medical Center and Chang Gung University is developing a monoclonal antibody drug, Liang said.
The FDA has also approved four — out of 13 applications — to manufacture COVID-19 testing kits and approved 19 — out of 75 — applications to import testing kits.
Chang Shan-chwen (張上淳), convener of the CECC advisory specialist panel, on Tuesday said that the prevalence of COVID-19 is expected to be less than 1 percent, or possibly under 0.1 percent, but the margin of error of rapid test kits means that those test results could be seriously misleading, with many false-negative or false-positive cases.
His comments came one day after the National Taiwan University College of Public Health and Changhua County Public Health Bureau began conducting COVID-19 antibody tests on about 10,000 county residents.
Such research can be conducted for academic purposes and must be carefully reviewed, although the results would likely have very limited impact on the government’s disease prevention or control policies, he added.
China has reserved offshore airspace in the Yellow Sea and East China Sea from March 27 to May 6, issuing alerts usually used to warn of military exercises, although no such exercises have been announced, the Wall Street Journal (WSJ) reported yesterday. Reserving such a large area for 40 days without explanation is an “unusual step,” as military exercises normally only last a few days, the paper said. These alerts, known as Notice to Air Missions (Notams), “are intended to inform pilots and aviation authorities of temporary airspace hazards or restrictions,” the article said. The airspace reserved in the alert is
South Korea is planning to revise its controversial electronic arrival card, a step Taiwanese officials said prompted them to hold off on planned retaliatory measures, a South Korean media report said yesterday. A Yonhap News Agency report said that the South Korean Ministry of Foreign Affairs is planning to remove the “previous departure place” and “next destination” fields from its e-arrival card system. The plan, reached after interagency consultations, is under review and aims to simplify entry procedures and align the electronic form with the paper version, a South Korean ministry official said. The fields — which appeared only on the electronic form
More than 6,000 Taiwanese students have participated in exchange programs in China over the past two years, despite the Mainland Affairs Council’s (MAC) “orange light” travel advisory, government records showed. The MAC’s publicly available registry showed that Taiwanese college and university students who went on exchange programs across the Strait numbered 3,592 and 2,966 people respectively. The National Immigration Agency data revealed that 2,296 and 2,551 Chinese students visited Taiwan for study in the same two years. A review of the Web sites of publicly-run universities and colleges showed that Taiwanese higher education institutions continued to recruit students for Chinese educational programs without
A bipartisan group of US senators has introduced a bill to enhance cooperation with Taiwan on drone development and to reduce reliance on supply chains linked to China. The proposed Blue Skies for Taiwan Act of 2026 was introduced by Republican US senators Ted Cruz and John Curtis, and Democratic US senators Jeff Merkley and Andy Kim. The legislation seeks to ease constraints on Taiwan-US cooperation in uncrewed aerial systems (UAS), including dependence on China-sourced components, limited access to capital and regulatory barriers under US export controls, a news release issued by Cruz on Wednesday said. The bill would establish a "Blue UAS
