Maternal vaccination coverage was 6.4 and 41.0 percent for influenza and Tdap, respectively. The researchers found that the risk for hospitalization or ED visits for influenza and pertussis was lower among infants born to mothers who received the influenza and Tdap vaccines (vaccine effectiveness, 69.7 and 88.6 percent, respectively)."These results support the current recommendations for administering these vaccines during pregnancy and highlight the urgent need to implement strategies aimed to increase their acceptance," the authors write.One author disclosed ties to the pharmaceutical industry.Abstract/Full Text.Sign up for our weekly HealthDay newsletter
