Any patient who believes that they have had a severe or unusual reaction to a vaccine is also welcome to submit one as well. If you feel you have suffered an illness, injury or serious reaction after receiving any vaccination, you should report this incident immediately to your supporting medical treatment facility or your parent command. Other adverse events can be reported as well. Usually, the side effects to this vaccine are mild and last just 1 or 2 days.
Larger reactions occur about once per hundred vaccinees or less.
A lump at the site occurs commonly, usually lasting for a few weeks, before going away on its own, if left alone. Large local reactions are rare, occurring in less than 1 percent of those vaccinated. Large reactions include swelling that extends to the elbow or forearm that can limit its movement, or a rash that is limited to the arm. These symptoms usually go away in less than a week. Serious events, such as those requiring hospitalization, are rare for any vaccine.
