Kobe has started to receive chickenpox vaccine on a regular basis, and the number of pediatric chickenpox patients who visited the Kobe Children's Early Emergency Center on Wakihama Kaigan-dori, Chuo-ku, Kobe has decreased by about 6% compared to the time of voluntary vaccination. It was found in a survey by Hiroshi Yamaguchi, Assistant Professor of the Graduate School of Medicine, Hirohiro Nozu, and Akito Ishida, Director of the Kobe Children's Primary Emergency Disease Center.
According to Kobe University, the research group used a clinical database to detect 2011 chickenpox out of about 2019 patients under the age of 16 who visited the Kobe Children's Primary Emergency Center from 26 to 5,000. investigated.
As a result, the number of patients per year was about 2014 before the varicella vaccine became a regular vaccination in October 10, but it decreased to about 500 after the regular vaccination.Furthermore, the number of patients tended to decrease even in 200-year-old children before vaccination.As the infection of older siblings living together has decreased, it seems that the chances of infection have decreased for 0-year-old children.
It was also revealed that about 6% of the patients who receive chickenpox have not been vaccinated, and the age group of the patients who receive the vaccine has been increasing in recent years.Due to the decrease in chickenpox patients, it was confirmed that the annual direct medical expenses alone decreased by about 400 million yen.
The vaccination rate was about 4% when the varicella vaccine was voluntary.The research group recommends vaccination to unvaccinated people and believes that subsidizing the cost can further reduce the number of chickenpox patients.
