On Sudden Infant Death Syndrome (SIDS) and vaccine use...sleeping environment is the main risk, vaccines show no increased risk

That quote comes from a new review of the current understanding of the risk factors for SIDS. 

SIDS is the leading cause of death in infants aged 1 month to 1 year in the United States.

While we don't know everything about SIDS yet, this review tells us that we do know some major risk factors for infants include:

• prone and side sleeping
• soft bedding
• bed sharing
• inappropriate sleep surfaces (including sofas)
• exposure to tobacco smoke
• prematurity

Protective factors include breastfeeding, pacifier use, room sharing, and immunizations. 
In other words, vaccinating your child is not a cause of SIDS. 

Facts matter because life matters.
