Vaccinate or hesitate: What parents need to know

Launch of Polio, Nairobi (Jenipher Wachie, Standard)

What began as a joyful Sunday School morning for 10-year-old Michelle Opondo, a time of singing, laughter, and shared memory verses, ended in confusion, fear, and a deep sense of betrayal.

As she and her 16-year-old cousin Viola Owuor were leaving church, they encountered a group of women in yellow overcoats waiting by the gate, coolers in hand. "They said they were there to vaccinate children," Viola recalls. "Other kids were lining up. So, I told Mitchel it was okay."
