The New School Absentees Reporting System for Pandemic Influenza A/H1N1 2009 Infection in Japan

Objective: To evaluate the new Japanese School Absentees Reporting System for Infectious Disease (SARSID) for pandemic influenza A/H1N1 2009 infection in comparison with the National epidemiological Surveillance of Infectious Disease (NESID). Methods:We used data of 53,223 students (97.7%) in Takamatsu city Japan. Data regarding school absentees in SARSID was compared with that in NESID from Oct 13, 2009 to Jan 12, 2010. Results: Similar trends were observed both in SARSID and NESID. However, the epidemic trend for influenza in SARSID was thought to be more sensitive than that in NESID. Conclusion: The epidemic trend for influenza among school-aged children could be easily and rapidly assessed by SARSID compared to NESID. SARSID might be useful for detecting the epidemic trend of influenza

Analysis of antibody-negative medical students after hepatitis B vaccination in Japan

Hepatitis B virus (HBV) vaccination is recommended for health-care professionals because of their frequent contact with blood. At one medical school, new students undergo HBV antibody tests upon admission, and antibody-negative individuals receive the HBV vaccine. We aimed to characterize individuals who remained antibody negative after HBV vaccination. Between 2009 and 2017, we enrolled 1064 first-year students from a medical school where their HBV antibody test and vaccination records remained. We analyzed data regarding the hepatitis B surface antibody (anti-HBs) test record during admission, vaccination record for antibody-negative participants, anti-HBs test result after completing the three vaccination doses, drug name of the vaccine used, sex, body mass index (BMI), and age. We calculated the yearly percentage of antibody-negative individuals and analyzed the characteristics of vaccine-refractory cases by logistic regression analysis. Of the 1064 participants, 999 were initially antibody negative. They were vaccinated with HBV thrice and tested for antibodies after vaccination. The average age of participants was 20.1 y, with 677 males. Although the type of vaccine has been changed since 2016, the average rate of refractoriness from 2009 to 2015 was 6.9% per year and 18.6% after 2016. Logistic regression analyses showed that sex (male vs. female; OR, 1.787), BMI (OR. 1.171), and vaccine type (genotype A vs. genotype C: OR, 3.144) were significant factors associated with antibody-negative individuals. Vaccine type differences altered the proportion of antibody-refractory individuals, with no association with age. The data on vaccine refractoriness will be continuously analyzed in the future while considering other factors

Parents’ hesitation about getting their children vaccinated against COVID-19 in Japan

Given the urgent global need for vaccinating individuals of all ages against the COVID-19 pandemic, understanding the extent and reasons for parents’ willingness to get their children vaccinated is important. This study used an internet-based questionnaire survey to determine parents’ willingness to get their children (0 to 15 years) vaccinated in Japan and was conducted in April 2021 before COVID-19 vaccination for children began. Socio-demographic information, information about parents’ willingness to get children vaccinated, reasons for their responses, and parents’ willingness to get themselves vaccinated were obtained. Descriptive statistics were used to evaluate parents’ willingness to get children vaccinated based on the other variables. Logistic regression analyses were conducted to identify the characteristics of parents who indicated willingness to get their children vaccinated and to identify the reasons for vaccine willingness. Of the 1100 respondents, 472 were willing to get children vaccinated, 470 were not sure, and 158 did not want to get children vaccinated. Considerable differences were found in the willingness to get children vaccinated across gender, age groups, occupation, annual income, respondent’s academic background, and respondent’s willingness to get COVID-19 vaccination for themselves. Reasons for being unsure about the vaccination included the vaccine’s potential side effects (84.9%), uncertainty about vaccine safety (54.7%), and not trusting vaccine efficiency (25.7%). Parents’ willingness to get the COVID-19 vaccine for themselves was a significant factor for their willingness to get children vaccinated after adjusting all other factors. The study recommends disseminating more and correct information to the public to increase vaccine willingness
