Significance of inoculation
Vaccines that are being inoculated in Japan have a high effect of preventing the onset of delta strains, etc., while the effect of preventing infection and the effect of preventing aggravation in the elderly are gradually increasing over time. It is suggested that it will decrease to.
Therefore, as a result of discussions at the council of the Ministry of Health, Labor and Welfare, from the viewpoint of preventing the spread of infection and preventing aggravation, additional (third) inoculation should be given to those who have completed the first (first and second) inoculation. It was said.
It has been suggested that the preventive effect of the first (first and second) inoculations on the Omicron strain is lower than that on the Delta strain, but that it is recovered by the additional (third) inoculation. The hospitalization preventive effect is also reduced to some extent compared to the Delta strain, but it is maintained more than the onset preventive effect, and it has been reported that it recovers with the additional (third) inoculation.
 | Inoculation is not compulsoryThose who receive the new corona vaccine should understand both the effect of vaccination against infectious diseases and the risk of side reactions, and then receive the vaccine on their own initiative . Inoculation will not be done without the consent of the recipient. If you are currently undergoing treatment due to some illness, or if you are worried about vaccination due to your physical condition, please consult with your doctor before considering whether to receive vaccination.In addition, there are those who do not wish to be vaccinated and those who cannot be vaccinated due to various reasons such as constitution and illness. Please do not force the vaccination to the workplace or those around you, and do not discriminate against those who have not been vaccinated.Consultation counter for bullying and harassment in the workplace(Link to external site)(Open in a new window)Contact for human rights consultation(Link to external site)(Open in a new window) |

Vaccine to use and inoculation interval

Regardless of the type of vaccine received in the first (first or second) inoculation, the messenger RNA (mRNA) vaccine is to be used.
Currently, the types of vaccines that can be additionally (third) vaccinated based on the Vaccination Law are as follows.
| Vaccine type | Target age |
|---|---|
| Pfizer’s new corona vaccine (messenger RNA (mRNA) vaccine) | Those who are 12 years old or older as of the date of inoculation |
| Takeda / Moderna’s new corona vaccine (messenger RNA (mRNA) vaccine) | Those over 18 years old as of the date of inoculation |
| Takeda’s new corona vaccine ( Novaxovid ) (recombinant protein vaccine) | Those over 18 years old as of the date of inoculation |
The variety of new corona vaccines has increased
From May 25, 2022, Takeda’s new corona vaccine (Novaxovid) has been added as a vaccine to be inoculated based on the Immunization Law . From July, Takeda’s new corona vaccine (Novaxovid) will be inoculated at the mass vaccination site of the Chiba Central Community Center from July.
If you have not received the additional (third) vaccination yet, please consider taking this opportunity to inoculate the new corona vaccine again.
[Comparison between Takeda’s new corona vaccine (Novaxovid) and other new corona vaccines]
- Ingredients contained
Although rare, the new corona vaccines from Pfizer and Takeda / Moderna contain “polyethylene glycol (PEG)” as an ingredient of concern for allergic reactions. On the other hand, Takeda’s new corona vaccine (Novaxovid) does not contain “polyethylene glycol (PEG)” but contains “polysorbate”.
Although I received the first (1st and 2nd) vaccinations, I was concerned about allergies to the ingredients contained in the new corona vaccines of Pfizer and Takeda / Moderna, such as “polyethylene glycol (PEG)”, so I added (3rd). ) Even those who have refrained from vaccination may be vaccinated with Takeda’s new Corona vaccine (Novaxovid).
- structure
Pfizer and Takeda / Moderna’s new corona vaccine (messenger RNA (mRNA) vaccine) and AstraZeneca’s new corona vaccine (virus vector vaccine) inject part of the genetic information that makes the viral protein. Takeda’s new corona vaccine (Novabacs) (recombinant protein vaccine) is a new type of vaccine that uses the spike protein gene on the surface of the new corona virus as a nanoparticle. It is a kind of inactivated vaccine.
Recombinant protein vaccines have a long-term track record of use in other vaccines such as hepatitis B virus vaccine in Japan.

Depending on the type of vaccine, the incidence of symptoms that may appear within a few days of receiving the vaccine varies as follows. Most of these symptoms have recovered within a few days of receiving the vaccination.
