The Facts:
Many studies have looked at vaccines and SIDS. SIDS stands for sudden infant death syndrome. It is when a baby dies suddenly, and doctors cannot find a clear cause, even after an investigation.
The evidence does not show that vaccines cause SIDS. Some studies found no change in SIDS risk after babies got vaccines. Other studies found that babies who got vaccines had a lower risk of SIDS.
Experts do not say vaccines prevent SIDS. That is because families who vaccinate on time may also be more likely to do other things that lower the risk, like putting babies to sleep on their backs. But the evidence does not show that vaccines raise the risk of SIDS.
We also should not guess what caused these children’s deaths. There may be a trial, and more facts may come out later.
What we do know is that the children died on May 1, 2025. Just three weeks later, their parents were interviewed by Children’s Health Defense, RFK Jr.’s anti-vaccine group. In that interview, they claimed vaccines caused the deaths, even though there was no medical evidence proving that.
