A British pharmaceutical company came to a sudden halt during final phase 3 after going through phases 1 and 2 of the COVID-19 prevention vaccine clinical trial.
It means that a participant in a clinical trial had an unexpected and serious “illness”.
This vaccine also had a supply contract with Korea, but the red light was turned on in anticipation that a vaccine could be developed within this year.
This is Han Soo-yeon.
◀ Report ▶
AstraZeneca’s COVID-19 vaccine, which is being developed in conjunction with the University of Oxford in the UK, is one of the three most promising candidate vaccines.
We have already signed supply contracts with major European countries such as the United States and the United Kingdom, as well as Korea.
The antibodies formed without major side effects in the results of the first and second clinical trials for 1,000 people, which were published in July.
Since last month, 30,000 people have entered the third stage test.
[파스칼 소리오/아스트라제네카 최고경영자 (지난 7월)]“We are thinking about mass production in September or October. Many people will be vaccinated before the end of the year.”
However, a serious side effect recently occurred in a British clinical trial participant and the clinical trial was completely stopped.
This is the first case of suspension of trials related to the development of a COVID-19 vaccine.
The link between the side effects and administration of the vaccine is not yet clear, but the New York Times reported that this side effect is “ transverse myelitis, ” in which the lower body is paralyzed due to inflammation. of the spinal cord section due to a vaccine or viral infection.
[맷 핸콕/영국 보건장관]“It would have been nice if it went smoothly, but the safety of the vaccine should be a top priority, so we are stopping clinical trials to investigate.”
In response, AstraZeneca said that clinical disruption is a common occurrence in vaccine development and that it will accelerate research to minimize disruptions to the schedule.
However, it will not be easy to develop a vaccine within a year due to the suspension of AstraZeneca’s clinical trials, which were the most advanced.
Currently, there are 9 COVID-19 vaccine candidates that have begun phase 3 clinical trials.
As concerns grew about speed battles, nine drug companies also signed an agreement that “if safety is not guaranteed, vaccines will not be approved.”
[앨버트 부를라/화이자 최고경영자]“We promised that all companies will submit (vaccination applications) only if safety and efficacy have been demonstrated in a well-designed phase 3 trial.”
However, more than 100,000 people in China are known to have already urgently received an unapproved corona 19 vaccine.
The US government continues to emphasize swift wars, such as announcing that it will distribute the vaccine before the November presidential election, so the controversy over the safety of the vaccine is unlikely to subside.
