Vaccsbook is a newly launched website aimed at improving global vaccination rates by allowing patients and healthcare providers to document vaccination histories. The platform evaluates an individual's past vaccinations against current schedules, highlighting any missed and upcoming vaccines. It recalculates the next required dose with each new vaccination recorded. Featuring vaccination schedules for over 60 countries, primarily focusing on developing nations, Vaccsbook also supports catch-up plans for individuals who were not vaccinated from birth. The service is offered free of charge to all users, with a strong emphasis on vaccination and immunization.
