Reports such as this are valuable because there might not otherwise be opportunities to see one-to-one correspondence between influenza virus and its vaccine. To understand in more detail the correlation between vaccination and natural infection, information about elevated antibody titers after infection and the presence or absence of antiviral medication in the natural infection group would be helpful. The efficiency of transplacental transfer of antibodies should be the same in both vaccinated and naturally infected pregnant women. If the antibody titer is low in the vaccinated women, additional vaccination during the antepartum period might be an efficient approach to protect young infants.
