Routine and voluntary vaccinations in Ichikawa City

Schedule setting is important for vaccination

When the baby is in the mother's belly, immunity to various diseases is inherited from the mother.
However, since the inherited immunity gradually decreases, it will be unprotected from the virus and the risk of various infections will increase.
It also may be aggravated and may require hospitalization or may be life-threatening.
It is vaccination to perform for the purpose of preventing it.
Vaccination number of times of the baby is also more than 10 times a year with only routine vaccination.
For each vaccine, the recommended age for vaccination is determined to take into consideration the age at which infection is likely to occur and the risk of infection. So, if you set a firm schedule from an early stage and receive vaccination efficiently, you can gain immunity quickly.

Routine vaccination and voluntary vaccination

There are two types of preventive vaccination: "routine vaccination" and "voluntary vaccination".

Routine vaccination

The "routine vaccination" which the country establishes as law and each municipality takes the initiative and carries out can be received free of charge (public expense) within the decided period.　(Depending on the autonomous community, it may be charged or partially paid.)
As it is determined to be highly contagious and highly in need of prevention, be sure to inoculate no matter how busy you are.
Voluntary vaccination

On the other hand, "voluntary vaccination" is to go to the hospital and inoculate separately if you wish.　As it is voluntary, you will be responsible for the expenses, but depending on the municipality, you may receive subsidies.
It is voluntary, but not always unnecessary. Since babies are likely to infections and lead to more cases of severe disease, it is better to receive it taking into consideration the risk at the time of infection.

Live vaccine and inactivated vaccine

There are two types of vaccination: "live vaccine" and "inactivated vaccine", which differ in nature.

Live vaccone

A live vaccine is a vaccine that has attenuated the toxins of live bacteria and viruses, and by inoculating it, it makes immunity in the same state as lightly infected with the disease.
It develops immunity by one or two inoculations, and the effect is considered to last for a long time.

After the live vaccine inoculation, you must have an interval of 27 days (4 weeks) or more until the inoculation of the next vaccine.
Inactivated vaccine

An inactivated vaccine is a vaccine that kills bacteria and viruses and takes out only the components necessary to create immunity, and several times of immunization are required to obtain immunity.

After the inactivated vaccine inoculation, you must have an interval of 6 days (1 week) or more until the inoculation of the next vaccine.
