The study was conducted by the Public Health Foundation of India (PHFI) in the wake of the increasing number of Acute Encephalitis Syndrome (AES) cases in eastern Uttar Pradesh.
It reviewed AES surveillance data for January 2011 to June 2012 from Kushinagar district in the state.
During the study, it was found that the vaccination history of 84 percent of AES cases in 2011 and 100 percent in 2012 were "unknown".
"At the crux of the debate lies quality surveillance for AES, including laboratory testing, which is necessary for understanding AES, planning interventions, and developing appropriate policy measures," said Manish Kakkar of PHFI.
