Four children in Hyderabad's Old City area developed rashes, fever and abdominal pain after they were reportedly administered the Measles Rubella (MR) vaccine.
According to Deccan Chronicle, the students from the Sultan Shahi School were rushed to hospital for treatment, and kept under observation for half a day.
The DC report adds that the parents of one child, who had a severe throat infection, blamed the vaccine.
This came even as the Greater Hyderabad Municipal Corporation (GHMC) said that it was conducting awareness programmes to dispel myths, after 164 schools in the city did not want to participate in the ongoing vaccination drive.
According to reports, GHMC Commissioner, B.Janardhan Reddy compared the campaign to the Pulse Polio campaign which made the state polio-free, and asked for cooperation from parents and teachers.
He also appealed to citizens not to get swayed by false video and audio clips being circulated on WhatsApp and social media.
The MR-VAC vaccine, which prevents measles and rubella, is generally administered to children between the ages of nine months and 15 years.
Last week, Andhra Pradesh's State Human Rights Commission (SHRC) issued notices to the Principal Secretary, medical and health, asking for a detailed report on the mysterious death of a 13-year-old girl.
K. Chenchu Lakshmi, a resident of Tadepalli, had died within a few hours of receiving an MR vaccine on August 17.
Following this, NGO Balala Hakkula Sangham moved the SHRC accusing officials of medical negligence, and demanding action against them.
However, authorities denied that it was the vaccine that caused her death, pointing out that her sister had received a shot as well.
