A female patient of an unspecified age received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; Solution for injection; Lot Number: EM9809; Expiration date was not reported), via an unspecified route of administration on 01Mar2021 at about 13:00 or 15:00 hr as dose 1, single for covid-19 immunisation. The patient' medical history included lymphoedema (history details in legs) from an unknown date and unknown if ongoing. The patient's concomitant medications were not reported. On 01Mar2021 at 18:00 hr, patient experienced very or extremely dizzy and was walking wobbly or couldn't walk in a straight line if she wanted to and felt like she was drunk or drinking that's what she does that but that was it looked like and very weak. Patient experienced lymphedema in the legs, started the evening of her vaccination (01Mar2021) and got worse the next day (02Mar2021). Prior to vaccination she had managed (in control) of her condition and she had lymph massages. However, after the vaccine her legs got really swollen to the point that her skin was very tight. Patient said she hadn't gotten this reaction in a year. However, the issue at hand was, she knew that she had lymphedema (history details) in legs and knew that the swelling was developing, the next morning (02Mar2021) when she woke up, her cheeks were very feverish. Patient was chill and got a little bit of rash on cheeks and face, but legs were continuing to swell and by the end of the day by mid-day, it was hard for her to walk that ankles had swelled up so much. The swelling went down on the morning of this report (04Mar2021), but it continued to swell up again as the day progressed. Patient wanted to know if these adverse events are associated with the vaccine. Patient was scheduled for a second vaccine and was not sure if she should take it because of the lymphedema and the side effects, was really feeling dizzy. Patient asked what the signs of a severe allergic reaction are. When paraphrased about her concerns, patient stated no. Firstly, it was both legs and secondly it was difficult to walk, was able to walk, the skin stretches so much. Patient did not want to put it that she couldn't walk but it was not normal walking like your skin was stretched so much, so it was in both legs. The rash did go away during the course of the day, it was very slight red, and it went away. Consumer was informed about the Pfizer Medical Information and filing a safety report. Further probing could not be done as consumer didn't want to share further information. Hence, limited information available over the call. Clinical outcome of rash was recovered on unspecified date in Mar2021, of legs got really swollen was not recovered while outcome of the other events was unknown.  No follow-up attempts are possible. No further information is expected.
