There seems to be a common misconception that vaccines are somehow associated with SIDS deaths. This is not true! Experts warn that the risk of leaving your baby unprotected is 1,000 times greater than any increased risk for SIDS. Because infants receive many immunizations during the critical development period from two to six months of age, and 90 percent of SIDS deaths occur within this time frame, it is only logical that many SIDS victims have recently received vaccines. This does not mean that the immunization had anything to do with the infant’s subsequent sudden and unexpected death. The cause and effect of immunizations and SIDS has been comprehensively studied for more than two decades. In fact, in countries where immunization schedules are different from those in the United States, the peak incidence of SIDS is still between two to four months. Currently, both the Centers for Disease Control & Prevention and the American Academy of Pediatrics recommend that infants receive multiple vaccines during their first year of life. If there were no vaccines, there would be many more cases of disease and along with them, more deaths.
