Studies by Nagasaki University and others have shown that the effect of preventing the onset of the new coronavirus was about 80% in elderly people who were vaccinated three times after the spread of the Omicron strain.

It is said that the effectiveness of the Omicron strain will be increased by the third inoculation.

Groups such as Nagasaki University have found 5169 men and women over the age of 16 who were suspected of having corona and were tested at 13 medical institutions in 10 prefectures from January to March due to the spread of Omicron strains. Based on the data, we analyzed the effect of the vaccine on preventing the onset.



According to the results presented at an expert meeting of the Ministry of Health, Labor and Welfare, the effect of preventing the onset of elderly people aged 65 and over when compared to unvaccinated people is that they receive a third dose of Pfizer or Moderna vaccine. It was 80.5% after 2 weeks.



In addition, for 16 to 64 years old, after receiving two vaccinations,


it was 35.6% within ▽ 90 days,


34.5% from ▽ 91 days to 180 days, and


▽ 34.8% even after 181 days. After receiving

the


third vaccination, it increased to 68.7%.



The research group says that the third dose will increase the efficacy of Omicron strains in people over the age of 16 including the elderly.



Takaji Wakita, chairman of the expert meeting, said, "This is the result of showing the effectiveness of the third vaccination even after the spread of the Omicron strain. Isn't it necessary to go? "
