Administration of<unk>  can pose risks and cause side effects. Most people who have taken the vaccine report normal, usually mild reactions. These reactions include a sore arm, fever, and body aches. Some people may have side effects ranging from serious to life-threatening. According to the FDA-approved prescribing information leaflet, "Common adverse events include inoculation site signs and symptoms, lymphadenitis, and constitutional symptoms, such as malaise, fatigue, fever, myalgia, and headache." These reactions are less frequent in people being revaccinated than those receiving the vaccine for the first time. As far as pregnancy goes, it is recommended that the vaccine should be given to pregnant women who have been exposed to smallpox. No contraindications exist to receiving the vaccine in case of an outbreak emergency. "Because the risk of maternal serious illness or death, prematurity, miscarriage, or stillbirth from a smallpox infection are greater than the risk of the vaccination, smallpox vaccine is recommended and should be offered to pregnant women in case of an outbreak emergency."
