Influenza is a serious problem for infants <6 months of age, whose hospitalization rates for influenza and associated illness are comparable with rates in the elderly. Because influenza vaccines are not effective in this age group, the optimal evidence-based strategy is to administer trivalent inactivated influenza vaccines during pregnancy. Immunizing with trivalent inactivated influenza vaccines in the second and third trimester is well studied and safe, not only providing protection for the pregnant woman and her infant <6 months of age, but also for the fetus by decreasing the risk for low birth weight.
流感对于6个月以下的婴儿来说是一个严重的问题,他们因流感及相关疾病的住院率与老年人相当。由于流感疫苗在这个年龄组中无效,基于最佳证据的策略是在孕期接种三价灭活流感疫苗。在孕中期和孕晚期接种三价灭活流感疫苗已经得到充分研究且安全,不仅能为孕妇及其6个月以下的婴儿提供保护,还能通过降低低出生体重风险为胎儿提供保护。
