Kids whose mothers have the flu while pregnant may be at slightly higher risk of developing ''infantile autism'' as toddlers.

That's what a new Danish study finds, after studying more than 100,000 women. Scientists say activation of a mother's immune system, such as by infection with the flu, could affect a fetus's developing brain.

The researchers note that 99 percent of women who had influenza did not have a child with autism.

Health officials recommend all women get a flu vaccine during pregnancy.

The study is in the journal Pediatrics.
