h1n1 shot reaction - hives

Anonymous
I got hives randomly last spring. I'd never gotten them before. It was terrifying. They started in the day, I thought it was mosquito bites. I woke up in the middle of the night, my legs were covered thigh to toe, it was seriously like a nightmare. The next morning they were gone, then by the evening I was covered head to toe, especially around my hips, thighs, all over my legs, and stomach (none on my face and fewer on my arms).

It was the most horrifying experience - I had no idea what they were from. They went away and, knock on wood, have never come back. I have no allergies or skin issues, had not traveled anywhere or eaten anything different.

FWIW, I had not gotten a vaccine of any sort for several years. So I know that hives have many causes. I never figured out what happened or where they came from. Are we sure all of these cases are triggered by vaccines, and if so, if it is just your body reacting to something foreign and working through it. It seems like you could get hives from anything. I blamed mine on something I had encountered that my body was fine with pre-pregnancy, but post pregnancy something had chemically changed. But it was just a guess.

my 19 month old received the H1N1 shot yesterday, and today had hives initially on the same leg as the injection site, and now they are all over his body. like the others on this site, he has never had a reaction to a vaccine before, including seasonal flu (1 month ago as well as 2 doses 1 year ago).

My son who is almost 3 broke out in hives with a fever about a day after the h1n1 vaccine. It took five days to get rid of them. The big concern I have is that the reaction is being pinpointed to something else due to the long time it took for him to get them after the vaccine - but it appears this is not isolated. Any info would be greatly appreciated.

http://vaers.hhs.gov/index

This reporting system is monitored and checked by government officials, doctors, pharmaceutical companies and others. It's the official reporting network for vaccine related reactions and is very helpful to start identifying trends and problems related to vaccines.

fwiw, I did a quick search on hives. There were quite a few more hives reports from the seasonal than h1n1 (more than 3:1) but it was a rough search and I need to refine it more to get a more accurate result.


You can search here:

Use 'Uticaria' for 'hives'. If the bumps are under the skin not on top you can search for Angioedema which is similar

I'd love to see if you find any info on this!

She is perfectly ok, no other symptoms, she has no allergies to eggs. I was told those bite-looking bumpgs it "should" go away after 1 or 2 days but after 48 hours it still shows up from time to time. I shows up quickly, remains for about 15 minutes then disapear. I would really like to know how many days other cases like mine took to resolve by themselves.


Just a little update on my case, this AM the daycare told me they noticed that last Thursday as well, 1 day before the vaccine! So now I'm lost big time. Looks like tomorrow I'm heading to the doctor. I'm sure he will ask me if anything changed related to food and other things of her environment. These questions are really difficult to answer and I'll probably get paranoid about everything in the house, from soap brand to the cat... I hope he will tell me it is just a virus and that it will go away after a few days, keeping my fingers crossed....

My 6 year old daughter appears to have hives. There are suddenly about 18 itchy small bumps all in the same general area (one leg and her lower abdomin). She received the H1N1 vaccine (nasal mist) four days ago. Never had an allergic reaction or hives prrior to this.

Just gave her Benadryl as I discovered this about an hour ago. It's possible she has bites from playing out in the leavers but my other daughter played in the yard & has no bites whatsoever.

I think 4 days is way too long to have a hive reaction... not saying she doesnt have hives, but I dont think it can be from the mist.

Has anyone experienced this before?

So are you allergic to the antibiotics in the vaccine? If so, did you not know you were or that those ones were in teh same class of drugs as penicillin (are they?)?

Really!? Wow, I never even thought of that!


New poster here, and our pediatrician has said the same thing. My older son has had hives/rashes at the tail end of viruses a couple of times--most recently this past week--and the ped said this is a pretty common response. So if the hives are related to the vaccine, perhaps it's a response to the introduction of the virus into the body.

FWIW, my son had the h1n1 vax almost three weeks ago and had no response at the time.

My 4 y.o. son got the vaccine on 10/29, same day as my 20 m.o. daughter. I have noticed about 4 hives on my son's body, plus his rear has been very itchy. I'm not sure when it started but at least the last 5 days. The last few nights I have put cortisone cream and/or benadryl anti-itch spray on his butt. Not sure if this is a reaction to the vaccine or something else. In fact it didn't occur to me until just now that there could be a link. DD has had no reaction that I know of...

I think I'll call the Ped about the hives but not sure whether I can say this was a reaction to the shot or not. Now I wonder if I should seek out the 2nd shot after 28 days. I don't recall him having a reaction to the seasonal flu vaccine he received in early October but could it also be that he had the two shots too close together (about 2-3 weeks)?

Someone talked about hives lasting and thought I would share my own experience--I had mono when I was about 18 and for at least the next 4 years (through college) I would get hives whenever I was cold. It was the weirdest thing and the doctors at the health clinic did not believe me so I had to take pictures. These were big welts and would appear mostly on my thighs, butt and lower stomach. Not sure when they finally stopped coming and were most likely a reaction to the virus. I told people I was allergic to the cold.

This makes me grateful my 3.5yr old got the flu 2 weeks ago and bounced back after 2 days. Sounds like these hives are worse than the flu.

I got horrible hives once in reaction to stress (first day back from maternity leave) and then they would reoccur due to cold - anywhere the winter air touched my exposed skin.

I would be unhappy if my kids got hives from a vaccine but I am not sure hives alone would be serious enough to make me NOT get a vaccine.

I tend to agree with this. Also, I have known two people who have gotten the hives from cold thing. Weird!
