Three teachers posted at a vaccination centre in Maharashtra's Jalna district have been suspended for dereliction of duty after a probe revealed that a 72-year-old man was administered jabs of two different Covid-19 vaccines, causing a health scare, a Zilla Parishad official said on Wednesday.

The senior citizen, a resident of Khandvi village, was administered the first dose of Covaxin on March 22 but instead of getting the second dose of the same vaccine, he was given the Covishield jab on April 30 at Shirti vaccination centre in Partur tehsil of the district, he said.
