With the national 4th vaccination rate of 10.4% and the vaccination rate of those in their 50s focusing on the Korea Centers for Disease Control and Prevention (KCDC) at 3.4%, Commissioner Baek Kyung-ran said that the new mutant vaccine could be developed or produced in December, making it impossible to vaccinate this year. looks like
Commissioner Baek said on the 28th, "The current epidemic BA.5 improved vaccine is predicted to be developed and produced by both Pfizer and Moderne in November and December, but there are still uncertainties. We plan to establish the vaccine after evaluating the preventive effect and epidemic status,” he said, adding that the time for a new vaccine will be 'after next year'.
Commissioner Baek continued, "The current preventive effect of the fourth vaccination targets the prevention of aggravation and death, so there are no plans to expand it further than the recommended target." We will review it," and announced that the current 'personal responsibility quarantine policy' will be maintained until early next year.
Currently, the 4th vaccination is a treatment response system, not quarantine, as there is a “recommendation” clause for those over 50 and those over 18 with underlying disease.
Lee Ki-il, 1st general coordinator of the major script, said in a broadcast on the 21st that about the improved vaccine developed by Pfizer and Moderna, "The vaccine is said to be released around August or September. When the vaccine is available, we told them to supply it to Korea as soon as possible." other information was revealed.
The Korea Centers for Disease Control and Prevention (KCDC) said on the 25th, "The amount of mRNA vaccines such as Pfizer and Moderna will be introduced within this year is about 60 million. “We have been in discussions with pharmaceutical companies such as Pfizer and Moderna to quickly introduce an improved vaccine,” he said.
In the announcement that day, ‘introduction within the year’ was changed to ‘sufficient inoculation in the second half’, and ‘consultation’ was mixed with ‘contract’.
Professor Lee Jae-gap (Hallym University, Department of Infectious Diseases) said, “It is known that the sub-mutation of BA.5 Omicron is stronger than the existing Omicron, and the effectiveness of the vaccine is much lower. It seems that the effect on the neutralizing antibody part drops by about a third,” he told YTN on the 12th.
Prof. Lee said on the 26th, when the number of confirmed cases reached 100,000, “the number of reinfection cases among the age groups with high virus contact due to high activity volume and the number of reinfections among the elderly are also increasing. predictable'.
Professor Jae-Hoon Jeong (Department of Preventive Medicine, Gachon University) at a briefing held by the Korea Centers for Disease Control and Prevention on the 28th, saying, “It is a little difficult to reach 300,000 people.” It is not as high as this concern, so it is unlikely that it will lead to a pandemic. ▲ Most Koreans were infected during the Omicron pandemic, so the reinfection rate is lower than in other countries.
According to the Korea Centers for Disease Control and Prevention (KCDC), as of the 27th, in addition to the 4th vaccination rate of 10.4% nationwide, those in their 50s have a reservation rate of 11.7% and an inoculation rate of 4.2% for 10 days.
The Korea Centers for Disease Control and Prevention (KCDC) said that even with the fourth vaccination, the effectiveness of preventing infection was 20.3%.
