Sir please answer my question. My brother tested positive for coronavirus on 27th april he had symptoms from 24th On 8th may that is on 14th or 15th day of his infection. He used a toilet my father also uses. And my father  went into the toilet only 5 min after he came out. Is there any risk to my father. He is asmptomatic. And my father has his 2nd dose of vaccine scheduled at 18th of may. Is the vaccine is going to be safe for him if he doesnt develope any symptoms?
