4 year old got the inhaled flu vaccine on 2 days ago and has a rash on her belly not itchy. Should we be concerned?

Probably not: Would expect resolution in a day or two. Benign and transient rash is typical side effect (although it may be unrelated) and does not indicate allergy or other severe adverse reaction to the vaccine. Follow instincts, make pediatrician aware if concerned. ...Read more

After getting a flu shot, the injection site swelled & was hot. It itched mildly. Now, 2 days after shot, I have a rash under my arms. Is this related?

After getting a flu shot, the injection site swelled & was hot. It itched mildly. Now, 2 days after shot, I have a rash under my arms. Is this related?

May be: The interval between your flu vaccine and the rash may suggest that the rash is due to the vaccine. However, it may be a coincidence. If it does not bother you, I would wait. If it itches, would take an antihistamine such as cetirizine, Loratadine or fexofenadine (all available otc). If no better if a few days, see your physician. ...Read more

Vaccine misadventure: Placing in in the wrong spot (too deep or too shallow in the muscle bulk can cause irritation!) sometimes a little tug or pull during im injection can irritate some delicate tissue! A little Benadryl (diphenhydramine) warm compress and avoiding scratching might go a long way! If it worsens, a quick visit to your md will take care of it! Good luck! ...Read more

Itchy skin rash all over body (except for face, neck, palms and soles) for 14 days. NO fever, NO flu-like symptons, NO lymph node. Can it be HIV ARS?

Itchy skin rash all over body (except for face, neck, palms and soles) for 14 days. NO fever, NO flu-like symptons, NO lymph node. Can it be HIV ARS?

Rash: It sounds more likely that it is an allergic reaction to something. The fact that it is not on the palms and soles of your feet makes other bad things less likely. Skin rashes are hard to diagnose and the diagnosis depends on where the rash is, the color, whether there are blotches, raised bumps and many other things. You can buy benadryl (diphenhydramine) in the pharmacy for itching and if it persists see DR. ...Read more

You can develop a shot reaction (mild) but it is not the flu. The nasal mist is a much weakened but live virus & rarely causes a mild flu like illness, but far less intense than a regular flu would be. ...Read more
