코로나19 백신 "모든 투약자 면역 반응 생성"...글로벌 혈장치료 임상도 40배 늘어<br /><br />Some promising signs of vaccines and treatments for COVID-19 are emerging.<br />Scientists at Oxford University in the U.K. say their experimental vaccine has led to an immune response in everybody who got the shot.<br />Clinical trials of treatments that use the plasma of recovered COVID-19 patients are also on the rise.<br />Choi Jeong-yoon reports.<br />A potential COVID-19 vaccine developed by Oxford University has reportedly produced a promising immune response in a large, early-stage human trial.<br />According to data published Monday in the medical journal, The Lancet,... 100 percent of some 1-thousand participants in the trial developed antibodies.<br />Jointly developed with pharmaceutical giant AstraZeneca, the vaccine also produced killer T-cells that help patients combat the infection by attacking the infected cells.<br />The World Health Organization welcomed the news,... but warned that there's a long road ahead.<br />"Effectively, we have 23 COVID-19 candidate vaccines in clinical development. And as of today, we add one candidate vaccine for which phase one clinical data is available...But again, there is a long way to go. These are phase one studies. We now need to move into larger scale, real world trials."<br />Other vaccine developers also had positive news, with America's Pfizer and Germany's BioNTech successfully immunizing their 60 participants.<br />Pfizer and BioNTech now plan to begin testing on some 30-thousand volunteers this month to prove the efficacy of their vaccine.<br />Human trials on treatments for the virus are also accelerating.<br />The effects of treatments like Remdesivir and hydroxychloroquine remain uncertain and are only reported to work on limited groups,... but a convalescent plasma therapeutic which uses COVID-19 antibodies extracted from recovered patients is on the rise as an alternative.<br />A website by the U.S. National Institutes of Health that tracks clinical trials in action shows the number of clinical trials for a plasma treatment increased to around 120 in July.<br />That's up from just 3 trials in March.<br />But while its considered one of the most practical treatments for the virus,...ramping up collection of the plasma is proving a challenge.<br />Choi Jeong-yoon, Arirang News.<br />
