NewsisRegarding the fact that Pfizer, an American pharmaceutical company, said that the new vaccine against coronavirus infection (Corona 19), which is being developed in conjunction with the German pharmaceutical company Bioentech, showed an effectiveness of more than 90% in Phase 3 clinical trials, the government rated it as encouraging, but said it should be on the lookout.
Young-rae Sohn, head of the Strategic Planning Division of the Central Accident Control Division of the Ministry of Health and Welfare, said at a press conference on the morning of the 10th, “The phenomenon of foreign pharmaceutical companies entering to phase 3 clinical trials and the results are encouraging, “but” It is premature to expect it to be too good. “
Sohn said: “Because the foreign situation itself is so bad, there seems to be a lot of anticipation.” “Since the outcome of phase 3 has not yet been achieved, the US FDA approved it in the future and the supply chain is re-established. You have to keep in mind that they will get caught.”
He added: “When phase 3 is completed and the supply chain is created and produced with the approval of the US FDA, it is necessary to consider the situation where it takes quite a long time from production to purchase to inoculation in Korea “. Even if an effective vaccine is released, it will take a considerable period of time for approval, production, supply, and vaccination, so we will maintain the existing quarantine system, such as social distancing and epidemiological investigations. We hope to present data such as the proportion ”. On the 9th (local time), Pfizer and Bioentech announced the effectiveness of their Corona 19 vaccine. The two pharmaceutical companies began phase 3 clinical trials in six countries, including the United States, in July this year, and administered the vaccine two times 44,000 people. Half of them, about 22,000 people, received a fake vaccine (placebo) that was not real. As a result of an interim analysis, 94 Corona 19 infected people among the subjects were screened first, and more than 90% were those who received placebo. That means that less than 10% of the actual vaccinated people are infected. The preventive effect of more than 90% is comparable to the widely used childhood measles vaccine, according to the New York Times (NYT).
However, a more detailed analysis of clinical participants can further reduce the preventive effect. Safety is more important than preventive effect. Experts are of the opinion that even if there are no major clinical problems, serious side effects can occur during the large-scale vaccination process, so the end result should be observed.
