What are the risks from HPV–Cervarix vaccine?
The HPV Cervarix® vaccine has been in use around the world for several years and has been very safe. However, any medicine could possibly cause a serious problem, such as a severe allergic reaction. The risk of any vaccine causing a serious injury, or death, is extremely small. Life-threatening allergic reactions from vaccines are very rare. If they do occur, it would be within a few minutes to a few hours after the vaccination. Several mild to moderate problems are known to occur with this HPV vaccine. These do not last long and go away on their own. • Reactions where the shot was given • Pain (about 9 people in 10) • Redness or swelling (about 1 person in 2) • Other mild reactions • Fever of 99.5 or higher degrees Fahrenheit (about 1 person in 8) • Headache or fatigue (about 1 person in 2) • Nausea, vomiting, diarrhea, or abdominal pain (about 1 person in 4) • Muscle or joint pain (up to 1 person in 2) • Fainting Brief fainting spells and related symptoms (such as jerking movements)
