摘要

Influenza vaccination in pregnancy reduces maternal illness, improves fetal outcomes, prevents influenza in the infant up to 6 months of age, and potentially improves long-term adult outcomes for the infant (table 1). These effects on four life stages are not widely known by policy makers, and we provide a summary with recommendations for policy and needed research. Influenza in healthy pregnant women has been recognised since 1918 to carry a two to five times increased risk of severe respiratory illness and admission to hospital compared with influenza in non-pregnant women. Increased influenza susceptibility in pregnancy and the availability of inactivated vaccine led to the recommendation in 1960 by US public health authorities that pregnant women should be a priority group for influenza immunisation (appendix).1 Canada, the UK, and nine other European countries have since adopted this policy. In 2012, WHO's Strategic Advisory Group of experts stated that the highest priority group for influenza vaccine is pregnant women, because both mother and infant benefit from a single antenatal dose (appendix). Results of many studies have shown that influenza vaccines are safe in pregnancy.
