In a paradigm shift in the field of public healthcare for underprivileged families, a 25-year-old Mumbaikar has developed an app that will offer mothers living in slums timely reminders to vaccinate their children. The brainwave for the app came to Swati Humbad, an employee with global financial services firm Morgan Stanley, around two years ago, when she was volunteering for an NGO called SNEHA, which works towards women and child healthcare. "I used to go for field visits to the slums of Malwani as a technology volunteer, trying to identify areas of improvement there. During one such visit, I came across a mother, who could not remember the birth date of her own child," recalled Humbad. "It struck me that if she cannot remember her child's birthday, how would she remember the vaccination schedules?" she added.
