the following problems were reported:
Mild Problems
- Pain (about 7 in 10)
- Redness or swelling (about 1 in 5)
- Mild fever (at least 99.5°F) (up to about 1 in 10)
- Headache (about 4 in 10)
- Tiredness (less than 1 in 3)
- Nausea, vomiting, diarrhea (about 1 in 5)
- Other mild problems reported include chills, body aches, sore joints,
rash, and swollen lymph nodes.
Moderate Problems
- Severe pain at the injection site (about 1 in 20)
