New corona vaccine supply uncertain by the Olympics 17:39 on July 22
It is said that some of the vaccines, which are trump cards to prevent the spread of the new coronavirus, may be confirmed to be effective within the year, but will it be supplied to countries around the world by next year's Tokyo Olympics? In an uncertain situation, experts say, "I can't be optimistic despite expectations."
Development of a vaccine against the new coronavirus is progressing at an unprecedented speed by utilizing the latest genetic technology. According to WHO = World Health Organization, as of the 20th of this month, 166 plans are in progress.
Of these, at least 24 vaccines have begun clinical trials to actually inoculate humans to confirm their safety and efficacy, and some have found that early clinical trials have shown that an immune response was triggered. It has been reported.
And,
▽Vaccine of a major pharmaceutical company "AstraZeneca", which has its headquarters in Oxford University and the United Kingdom,
▽ Vaccine of a Chinese pharmaceutical company "Shinovac",
▽ A vaccine of an American pharmaceutical company "Moderna"
has been inoculated to many people. The final stage 3 trial to confirm safety and efficacy has begun.
In China, a vaccine from another company, Cancino Biologics, was reported to be specifically approved and vaccinated against the military before the final trials.
Regarding vaccines, Dr. Anthony Fauch, who is a countermeasure against infection in the Trump administration of the United States, predicts that at least one may be confirmed to be effective or safe at the end of this year or early next year. Is shown this month.
However, since there is concern that production will be limited even if vaccine development succeeds, the WHO = World Health Organization has repeatedly emphasized that countries need to cooperate so that the vaccine can reach the people who need it. It was.
Expert "Excessive expectations should be avoided"
Regarding whether the development of a new coronavirus vaccine will be in time for the Tokyo Olympics and Paralympics, which will be approaching one year later, Professor Ishii of the Institute of Medical Science, the University of Tokyo, who is familiar with vaccine development, said, ``We are hopeful but never optimistic yet. No," he said, saying that excessive expectations should be avoided.
Professor Ishii said of the recent development status: "The first results of clinical trials were announced in the United States and the United Kingdom, and they were found to have strong immunity-inducing properties. However, what we have found is that when a vaccine is applied, antibodies are produced. "I just don't know if the immune response will work to protect against the new coronavirus or if it doesn't work, just because an immune response occurs. I'm hopeful but never optimistic yet." I explained.
He said, "In the normal case, we will gradually proceed with safety testing, but this time we will progress steadily, and there will remain the risk of being "not regretful" when there is a safety problem. Should be understood."
After that, regarding the prospects for future development, "while looking at the efficacy and safety of vaccines from now on, the situation in which the initial results are good, but I do not know what will happen afterwards will continue for a while" Although there are expressions such as "toward" or "by the Olympics" or as if the vaccine was taken hostage, it should be stopped with a bad expression. Although it is possible that the vaccine can be imported from foreign countries by the Olympics, it is subject to vaccination First, health care workers and high-risk people are a priority, and it may not be possible for everyone to be vaccinated by the Olympics."
