Possible Side-effects from Vaccines http://www.cdc.gov/vaccines/vac-gen/side-effects.htm
'Any vaccine can cause side effects. For the most part these are minor (for example, a sore arm or low-grade fever) and go away within a few days. Listed below are vaccines licensed in the United States and side effects that have been associated with each of them. This information is copied directly from CDC's Vaccine Information Statements, which in turn are derived from the Advisory Committee on Immunization Practices (ACIP) recommendations for each vaccine.' 'Remember, vaccines are continually monitored for safety, and like any medication, vaccines can cause side effects. However, a decision not to immunize a child also involves risk and could put the child and others who come into contact with him or her at risk of contracting a potentially deadly disease.' EXAMPLE: Yellow Fever vaccine side-effects What are the risks from Yellow Fever vaccine? A vaccine, like any medicine, could cause a serious reaction. But the risk of a vaccine causing serious harm, or death, is extremely low. Mild Problems: Yellow fever vaccine has been associated with fever, and with aches, soreness, redness or swelling where the shot was given. These problems occur in up to 1 person out of 4. They usually begin soon after the shot, and can last up to a week. Severe Problems: Severe allergic reaction to a vaccine component (about 1 person in 55,000). *Severe nervous system reaction (about 1 person in 125,000). *Life-threatening severe illness with organ failure (about 1 person in 250,000). More than half the people who suffer this side effect die. These last two problems have never been reported after a booster dose.
