Brief Answer: Kindly provide few more details Detailed Answer: Hello, Thanks for your query. As the flu vaccine contains dead virus, an allergic reaction to it is very rare. However, an individual can be allergic to other constituents of the vaccine like delivering agent or preservative agent of the vaccine. Since you took the vaccine on Friday & symptoms appeared on Monday, it can be either a delayed hypersensitivity reaction to the constituents of the vaccine or due to an immediate hypersensitivity reaction to some other allergen not related to the flu shot. Regarding the symptoms as mentioned in your post, kindly let us know about the following: 1. Do you have an allergy to eggs? 2. Any previous history of similar allergic reactions? 3. What were you doing when you first noticed the symptoms (hive on forehead and neck with achy joints)? 4. Since how many days you are taking Levothyroxine & Triamterine? A knowledge of the above mentioned questions will be helpful in understanding your concern better. Hoping to hear from you soon. Wish you a good health. Take care.

Brief Answer: Delayed hypersensitivity reaction to viral protein Detailed Answer: Hello, Thanks for your follow up query. Based on your case history, the symptoms can be attributed to delayed hypersensitivity reaction to viral proteins. Swelling in throat is due to angioedema, which was not present during the symptoms in previous episode 2 years ago. The medications given by your Doctor are correct, kindly continue them as advised. There is no need to worry, you will be fine. And if you take any vaccination in the near future, then please be careful & the administering Doctor should be made aware of this. Wishing you a Good Health. Take care.
