Had no reactions afterwards except 3 hours afterwards she had a reaction in the severe list, it was extreme dizziness and when raising her head up it made her nauseous and that lasted about 6 hours.   Is not sure if anyone has said anything else about swelling in the feet and has never had swelling in her feet or legs in her life. Since after the shot she has had the swelling in her feet and she went to see the doctor. The doctor gave her water pills and she is a little concerned because her feet are always freezing and she has never had warm feet in her life, but since they are swollen they are warm. Does not know what to do about the second shot because she heard you are more likely to have side effects worsen. Doesn't know if she wants worsening side effects and doesn't understand now the same shout is given to someone that weighs 110 pounds as a person who weighs more than 110 pounds. Are medications based on weight.  When clarifying which vaccine, caller provides lot number from card. No further details provided. Declines to provide an address, but provides email address.
