Maternal Influenza Vaccine

The pooled maternal influenza vaccine effect estimate was OR 0.79 with 21% vaccine effectiveness against all-cause ALRI hospitalisation in infants under six months. Four studies qualified for the maternal influenza vaccine meta-analysis against all-cause ALRI in infants under six months. The maternal influenza vaccine meta-analysis had moderate, statistically significant heterogeneity. Maternal influenza vaccination is described as the only available influenza prevention strategy for infants under six months.
