Question: My husband just got diagnosed with flu. His doctor did not specify which strain. We both received the flu vaccine in the fall. How likely is it that I can catch it from him?

Brief Answer:
Chances are low but avoid frequent contact! Approximately 50%

Detailed Answer:

Flu vaccines prevent most infections but not totally. You still have bout a 50% chances getting infected. I will suggest that you try to keep away from coming in contact with respiratory secretions from your husband. Keep the doors open, he should always cough/sneeze into a tissue, dispose off carefully, etc. This way, you can greatly reduce the chances of contracting the virus and developing an infection.

I hope this helps. I wish you well. Keep me updated about your progress. I wish you well.

My son had a flu vaccination on Jan. 20th and has had multiple symptoms since then. He has had eye twitching, shortness of breath, tightness in the chest, headaches, dizziness (disoriented feeling), ringing in the ears (only once), blurry vision, and muscle soreness. This is just over 4 weeks from the time of the vaccination and after a round of z-Pack, and zyrtec, and aleave, or Tylenol for the muscle soreness and headaches, he is improving, however, he still begins feeling sort of bad around 9:30pm and the disorientation comes back. Also, the eye twitching still comes and goes. We feel he is having side effects from the flu vaccination and were also wondering if Guillain Barre Syndrome might be a factor here. If so, we don t think it is a severe case. Wondering how long his symptoms might continue and is there anything we should be doing that might help other than the ibuprofen or aleave for muscle soreness?

I am going to Cambodia on November 3rd on a mission trip. On Sept 20, I began my series of required vaccinations. I received the Hep A and B vaccines that day. About 4 hours after getting the vaccines, I began having pain in my right shoulder, collarbone and down my right arm. I still have pain in these areas, sometimes mild and sometimes moderate to severe. In the last week I have developed pain in my right jaw, temple, ear and the right side of my neck. Is this the result of the vaccines. I m starting to get concerned.

I have been having nausea, vomiting and constipation on and off for about 4 months now. It seems to get really bad after I have to have some kind of shot. The first time it was the flu shot. This last time it was an anthrax shot. The doctors where I am have no clue what is wrong because my blood panel keeps coming back normal.
