Three children, aged 10 to 12 years, died and five others fell sick after being administered the vaccine in different areas of western Tripura.

Of the three children, Saheli Debbarma, 12, fell ill after taking the vaccine on May 28, 2015, and was shifted to a Kolkata hospital on June, 1, 2015. She died on Tuesday night, June 2, 2015.
According to health department experts, as per protocol of the JE vaccine, it is not supposed to be administered when a child already has fever or any other disease. An official said, "The union health and family welfare ministry had decided to hold a vaccination drive in 27 affected districts across the country."
Nagaraju said, "Since May 23, 2015, over 210,000 children aged 1-15 years across three districts have been administered JE vaccines. The JE vaccine is safe like other vaccines in use in Universal Immunization Program. Minor side effects like pain, mild swelling and mild fever may occur. Serious adverse events like hypersensitivity reaction may occur in one-in-a-million cases. Beneficiaries are screened for contra-indications before vaccination by trained vaccinators. The state government appeals to the people not to panic as the vaccine is safe and the most powerful means to prevent the JE disease."
