Whisper launched the 'The Missing Chapter' campaign, as the next edition to its #KeepGirlsInSchool initiative, to fight period taboos and advocate the inclusion of period education in the mandatory school curriculum to prevent girls from dropping out of school. The film illustrates how a girl's lack of period education contributes to her missing school days, a situation exacerbated by the glaring absence of period education in Indian textbooks. Some studies indicate that even today, 1 in 5 girls drop out of school when their periods begin, and 71% of adolescent girls in India are not aware that menstruation occurs until they begin their period. The pandemic has made this worse as schools shut down. By advocating for the mandatory inclusion of period education in the school curriculum, 'The Missing Chapter' aims to make a real impact on the ground.
