Study backs safety of flu vaccine in pregnant women

US researchers compared complications in 76,000 vaccinated women (28% vaccinated in the first trimester) with 148,000 unvaccinated women.

Vaccination was not associated with increased risk of allergic reaction, cellulitis or seizures in the first three days, nor with incident Guillain-Barré syndrome, transverse myelitis, or Bell’s palsy.
