Noida: The gang behind the alleged black marketing of the Remdesivir injection was also selling Covishield vaccine on various Facebook groups since March, evidence with TOI suggests. Screenshots of different Facebook pages of these online groups — like Pharma Franchisee and Medical Goods India — clearly show how the accused, Rachit Ghai, had been selling doses of 5 ml Covishield vaccine much before he was caught. In one of the screenshots of the Facebook page, Medical Goods India, with over 16,000 members, Rachit posted on March 18 that Covishield was available for sale. In another screenshot, the accused posted on April 1 about the availability of the vaccine.
