ZZZ to ZZZ1 during boarding as Flight Attendant A was preparing cabin for departure. Passenger A seated in seat XXA (which was not her assigned seat) was informed by Passenger B in seat XXB that she wasn't feeling well. (Who should have been seated in seat XXA).Passenger A asked FA A if she could be moved; felt uncomfortable sitting next to Passenger B. Passenger A was flying home to visit someone who had been in hospital and didn't want to take a chance by flying in to ZZZ seated next to the other passenger. FA A informed FA B that a passenger was not feeling well and that the passenger seated next to her wanted to move. I moved Passenger A up one row where she should have been seated. And ask Passenger B why she wasn't feeling well finding out she had a sore throat and coughing and just felt bad. I ask if she thought she could fly or wanted medical assistance she said she thought she would be ok and wouldn't need any.Per Medlink; guest was not approved to fly and was removed. Passenger count was correct and flight departed.
