Free text: Im unsure if its related but approximately 90 minutes after the injection I ate my first meal of the day which was a salad. It was a basic salad with spring mix lettuces, chicken, avocado, sunflower seeds, and Caesar dressing. All of the ingredients are regular for me except for the seeds which Ive had before sparingly and with no reactions. This time however, shortly after eating the salad my lips were swollen. The mucus lining in my mouth was also reacting. I knew I was having a reaction to something...I believe it was the seeds...I took some benadryl and was fine the next morning. I considered my symptoms as mild.

Each entry is dated by the survey it was written in (the CDC re-sent the releases with survey dates in 2025); click a date to see that survey response. The CDC cut some text off at about 250 characters: symptoms in every release, and the other two fields in releases 9-12. Those entries are marked "cut off by CDC".
