Regarding the third inoculation of the new coronavirus vaccine, a research group of the Ministry of Health, Labor and Welfare announced the analysis result that a certain onset prevention effect was confirmed even 3 months after the inoculation.

A research group of the Ministry of Health, Labor and Welfare investigated how the antibody level against the "conventional strain" before mutation changed when a person who had been vaccinated up to the second time hit the modelna or Pfizer for the third time.



As a result, in 152 people who received the modelna three times, the antibody level was


19.5 times on average after 1 month


and 9.9 times after 3 months compared to immediately before the inoculation.



In addition, in the 179 people who switched to Pfizer for the third time,


the antibody level after 1 month was 17.9 times higher than that immediately before inoculation, and


9.3 times after 3 months.



People who have been vaccinated with Pfizer up to the second time have seen the same tendency when they hit Pfizer or Moderna the third time.



Suminobu Ito, a specially appointed professor at Juntendo University School of Medicine, who is the representative of the research group, said, "Although the antibody level is almost halved from 1 month to 3 months after the third vaccination, it develops with any combination of vaccines. The effect of preventing the disease is maintained to some extent. "

Changes in antibody levels depending on the type and combination of vaccines

A research group of the Ministry of Health, Labor and Welfare has quantified how the antibody level changed after the third vaccination depending on the type and combination of vaccines.



The antibody value when the Pfizer is hit three times in a row is


▼ 378 immediately before the third vaccination ▼ 19,674 ▼ one month later 19,674


10,376 three months later

the third vaccination with Pfizer twice.

▼ 409 immediately before vaccination

after

▼ just before vaccination

One month later is 19,248

▼ Three months later is 9768

If you hit Moderna twice and switch to Pfizer the third time,
