Last week, I had a cold or something, no fever. I had an appointment for a swine flu vaccine on Friday, and by then I was feeling mostly better so I went and took it. I did not get the shot, I got the nasal spray. Now, 5 days later, I have a slightly sore throat, cough that is getting worse, I am achy, tired, and I have a fever of 100.1. Is it possible I caught the swine flu from the vaccine?
