Summary:

• **COVID vaccines are safe during pregnancy**: Scientists studied thousands of pregnant women who received COVID vaccines and found that their babies did not develop autism at higher rates than babies whose mothers didn't get vaccinated. This means the vaccine does not cause autism in children.

• **How scientists know this is true**: Researchers carefully looked at medical records of many families and compared the health outcomes of children whose mothers were vaccinated during pregnancy with those whose mothers were not. They found no difference in autism rates between the two groups, which proves the vaccine is safe for pregnant women and their babies.
