The patient was given SEPTRA to be taken for 7 days on 30-SEP-2010. The patient still had some redness and swelling since the medical assistant spoke to her on 08-OCT-2010. The patient was told by 2 physicians that their opinion was the patient had these reactions because the vaccine itself was contaminated.
