Smartphone app enables users to keep COVID-19 vaccination records Today 06:00 am JST Today | 07:15 am JST TOKYO A Tokyo-based medical venture has introduced a smartphone app feature enabling users to keep records of their COVID-19 vaccinations as many companies and universities have started administering doses to curb infections. The new feature has been added to MinaCare Co's free vaccine and health monitoring app as it may become difficult for individuals to keep track of their inoculation history, especially when they receive shots at workplaces and schools without vaccination tickets issued by municipalities. The Health Amulet app can automatically record the names of vaccine developers and manufacturers, while allowing users to insert information such as vaccine lot numbers, and their past and scheduled dates of inoculation.
