Vaccine efficacy
4th vaccination
In an overseas study, when a fourth dose of the Pfizer vaccine was given to a person aged 60 or over who had been inoculated for at least four months after the third dose, the preventive effect against severe disease during the Omicron strain epidemic decreased even six weeks after the vaccination. It was reported to have been maintained without
3rd inoculation
It has been reported that people who have received the third vaccination are less likely to be infected with the new coronavirus or become severely ill than those who have not.

Effect of 3rd inoculation using a vaccine different from 1st and 2nd 
It has been reported that the antibody titer will rise sufficiently in both cases where a person who received the Pfizer vaccine in the first and second doses receives the Pfizer vaccine and the Moderna vaccine in the third dose .
*Takeda/Moderna's vaccine has been approved by the pharmaceutical affairs in Japan with a booster dose of 50 μg, but in this study, 100 μg was administered.
1st and 2nd vaccination
The new coronavirus vaccine administered in Japan is highly effective in preventing the onset of new coronavirus infections, and it has also been confirmed to be effective in preventing infection and aggravation. Although it is possible that the infection prevention effect and the onset prevention effect may gradually decrease over time, it has been reported that the severity prevention effect remains relatively high. It has been confirmed that Pfizer's vaccine is approximately 95% effective in preventing the disease, and Takeda/Moderna's vaccine is approximately 94% effective in preventing the onset of the disease.
Also, research is progressing on how effective the vaccine is against mutant strains.
Risk of side effects
4th vaccination
An overseas study reported that no serious side effects were observed up to 21 days after the fourth inoculation.
3rd inoculation
In the pharmaceutical approval of the Pfizer and Moderna vaccines, there is a difference in the incidence of some symptoms in both vaccines, compared to those after the first and second vaccinations, for side reactions within 7 days after the third vaccination. However, most of the symptoms were similar to those of the first and second vaccinations.
1st and 2nd vaccination
In general, vaccination creates immunity and has the effect of preventing the onset and severity of illness, but various biological reactions may appear during the process of immunity. After vaccination, pain at the injection site, fever, malaise, headache, pain in muscles and joints, chills, diarrhea, etc. may occur, but most of the side effects will resolve within a few days. In addition, rare cases of anaphylaxis (acute allergic reaction) have been reported. Symptoms such as fever, general malaise, and headache tend to occur more frequently after the second dose than after the first dose.
