Pneumococcal infection

Streptococcus pneumoniae is one of the two major causes of bacterial infections in children.
This bacterium is carried by many children in the back of the nose and sometimes bacterial meningitis, bacteremia, pneumonia,
It causes diseases such as sinusitis and otitis media.
The incidence of purulent meningitis due to pneumococci is set at 100,000 to 2.6-2.9 for a population under 5 years old.
It was estimated that around 150 people developed the disease annually (*).
The mortality rate and sequelae (hydrocephalus, hearing loss, mental retardation, etc.) are higher than that of hib meningitis.
About 21% are said to have a poor prognosis.
*Based on data from Vaccinations's Infectious Diseases Subcommittee on Health and Welfare

(booster shot is based on 12 to 15 months of age.)
※The second and third vaccinations are performed by the age of less than 24 months.
(If you are over 24 months old, do not do it, but only once in booster shot is performed only once.
In addition, when first second inoculation exceeds 12 months after birth, we do not perform third inoculation and perform booster shot only be given once.

If you have already started vaccination with a 7-valent vaccine, inoculate the remaining dose with a 13-valent vaccine.
In addition, about one that inoculation of the number of times already established by 7-valent vaccine was finished, more than 8 weeks passed.
