Experts have met on the current status of the new coronavirus vaccine, and although it is highly possible that vaccines that have already been inoculated in the United States and other countries are effective, it is necessary to carefully verify their safety and sustainability. He showed the view that there is.
Regarding the vaccine for the new coronavirus, vaccination by American pharmaceutical giant Pfizer and others has already begun in the United States and the United Kingdom, and vaccines developed by the American pharmaceutical company Moderna have also begun shipping.
On the 21st, Hideki Hasegawa, director of the National Institute of Infectious Diseases Influenza Virus Research Center, who is involved in vaccine development in Japan, met and explained the safety and efficacy of vaccines.
Among them, Director Hasegawa said that both the vaccine by Pfizer and the vaccine of Moderna are 10 days after the first vaccination, compared with the group that received the fake drug "placebo" that resembles the vaccine. He said that the incidence is low and is likely to be effective, at least in the short term.
On the other hand, he pointed out that even those who received these vaccines in clinical trials have only been inoculated for about 3 months, so there are still unclear points about how long the effects will last and the safety.
It has been reported that 6 people in the United States showed severe allergic symptoms with the vaccine developed by Pfizer and others, but Director Hasegawa divided the side reactions into 1 week, 3 months, and after vaccination. He said that it is necessary to think about it and that the mechanism is different, so it is necessary to carefully examine it in the future.
Director Hasegawa said, "Side reactions may occur a long time after vaccination, so we need to continue to carefully monitor the safety and efficacy."
