On February 19, 2003, 206 children were administered insulin instead of Hepatitis B Vaccine at the Government Primary Health Centre, Kalliyoor, in Thiruvananthapuram district, Kerala. The authorities at the centre realised the error only after the “vaccine” was administered to all the children. Many of the children, aged between 1 and half months to 14 years, who complained of giddiness were rushed to government hospitals by the PHC staff. The then District Medical Officer K. Shylaja, had quickly and sternly ordered disciplinary action against the doctor in charge and five junior nurses for dereliction of duty. 14 years later, on May 2, 2017, in a bizarre twist of events, the former director of Health Services V. K. Rajan and K. Shylaja, the very DMO who had ordered the disciplinary action, have been sentenced to five years of rigorous imprisonment and slapped a penalty of Rs 52 lakhs each by the vigilance special court for procuring excessive amounts of Hepatitis B vaccines vials causing a loss of Rs 1.49 crores to the state exchequer.
