There is actually a diagram of the proper method in the Health Care Provider's Briefing located on our web site. I am including a hotlink so that you can take a look at the picture yourself. Like all vaccines, anthrax vaccine may cause soreness, redness, itching, swelling, lumps and may feel warm to the touch at the injection site. Lumps can persist a few weeks, but eventually disappear. Injection-site problems occur about twice as often among women.
Larger reactions occur in about one in a hundred vaccine recipients.
Again, these symptoms usually go away after a few days. Serious events, such as those requiring hospitalization, are rare. They happen about once per 50,000 doses. Severe allergic reactions can occur after any vaccination, less than once per 100,000 doses. The symptoms your husband has developed are common and should go away on their own in a few days.
