Hum Vaccin Immunother. 2021 Nov 2;17(11):4673-4674. doi: 10.1080/21645515.2021.1958612. Epub 2021 Aug 6.


Although routine vaccinations in children decreased during the coronavirus disease 2019 (COVID-19) pandemic, pneumococcal vaccine coverage in older adults has remained unknown. This study was performed to investigate the impact of the COVID-19 pandemic on pneumococcal vaccination in Japan. The numbers of 23-valent pneumococcal polysaccharide vaccines (PPV23) shipped was obtained from an office memorandum released by the Ministry of Health, Labor and Welfare. The results showed that the COVID-19 pandemic increased the need for pneumococcal vaccination, causing shipping restrictions of pneumococcal vaccines. Regular vaccination is still important because there may be a shortage of vaccines during a pandemic.
