A final-year student pursuing MBBS tested positive for coronavirus days after getting inoculated by the second dose of the Covishield vaccine, Indian Express reported.

According to the doctors at Sion Hospital, Mumbai, the vaccine takes several days to build immunity even after the administration of both doses of the vaccine.

The 21-year-old received the second dose of the Covishield vaccine last week. Days after inoculation, he developed mild symptoms of Covid-19 infection. He was then admitted to Seven Hills hospital on Saturday night.

Dr. Balkrishna Adsul, in charge of Seven Hills hospital, said to I.E: “Not everyone who gets vaccinated will develop an immune response in a set time frame.”
