Objectives

Narrative objectives1

The SARS-CoV-2, which has been spreading worldwide since 2019, has been spreading to children with the emergence of mutated strains. Vaccination against SARS-CoV-2 has been available in Japan since 2021. In Japan, vaccination against SARS-CoV-2 started in 2021, but children under 11 years of age have not yet been vaccinated.
In March 2022, Juntendo University Shizuoka Hospital plans to take the lead in vaccinating children aged 5-11 years in Izu no Kuni City, Shizuoka Prefecture, in accordance with the expansion of the indication of the SARS-CoV-2 vaccine (Cominaty, Pfizer) to children.
Therefore, we will conduct epidemiological studies of children who have been vaccinated with the new corona vaccine by collecting basic information on the children and their subsequent adverse reactions in a database managed by a questionnaire-based registration method as well as the Vaccination Facilitation System (V-SYS). In addition, for children who have given their consent to a backward-looking observational study, we would like to investigate subsequent adverse reactions, the spread of infection, and immune response. By analyzing these results, we will be able to evaluate the significance, safety, and persistence of immunity to the SARS-CoV-2 vaccine in children, which will provide important basic information for the control of infection.

Assessment

Primary outcomes

Epidemiological study and safety assessment
All children and their parents presenting for SARS-CoV-2 vaccination will be informed about the questionnaire and consenting patients will be allocated anonymously for enrolment.
Children who agree to be observed retrospectively will be included in a separate database. The incidence of post-inoculation symptoms will be monitored, distinguishing between local and progressive adverse reactions.

Key secondary outcomes

Immune persistence
A separate database will be created for children who agree to be observed retrospectively. Subsequent infection status and antibody testing (if desired) will be carried out.
