This report is made by GSK without prejudice and does not imply any admission or liability for the incident or its consequences.   Additional details were provided as follows: The case was reported by the patient for herself. Within one hour after vaccination, she experienced toxicity from the yeast growing in her body. She claimed that an hour later, her entire body was toxic.  She experienced a tightness in her head near her temples that lasted 24 hours and started after an hour of getting the vaccine. She had a sensitivity to antibiotics and she believed that her reaction was due to the antibiotics in the vaccine. The pain went to her back due to yeast proliferation and she had to take out her back massager. She has a sensitive system due to bacterial imbalance for most of her life. She was diagnosed with low iron 6 years ago. She claimed that her body could not absorb iron and they attributed it to being perimenopausal but the yeast was taking the iron from her because irons feeds bacteria. She was having a similar reaction in her body from the Fluarix vaccine. She was experiencing toxicity from the yeast growing.  The patient used Oreganol which was a wild oregano oil regularly for her immune system. She took wild oregano oil three times per day and the back pain would worsen initially and then she would use the back massager and the second and third days her emotions would be off the charts. She was feeling better yesterday but today she feels a little off due to eating chocolate.  She did keep improving in general after using the Oreganol but if she takes the product with bread she could feel a little woozy which happened the other night. She claimed that the Fluarix affected her behavior and makes her anxious. The patient was holistic.
