2013年8月15日讯 /生物谷BIOON/ --一直以来都流传着一种说法，那就是孕妇接种流感疫苗可能会出现各种不适。虽然这种说法并没有什么科学证据支撑，但是很多家庭的确因此而放弃让孕妇在流感高发期接种流感疫苗。最近发表在Obstetrics and Gynecology的一项研究通过调查收集了74000名孕妇接种流感疫苗后的情况发现接种流感疫苗并没有对孕妇造成危害。这是迄今为止关于这个问题最为详细和科学的调查。研究人员表示孕妇接种疫苗不仅不会对孕妇和胎儿造成危害，，胎儿还会从母体注射疫苗后获得对病毒一定的抵抗能力。（生物谷Bioon.com）

The risk vaccines pose to pregnant women is one of many safety topics in which popular opinion differs from scientific evidence. Multiple studies have found no evidence of harm, but surveys show people are unsure. The case in favor of vaccines became stronger still this week.

Research in the journal Obstetrics and Gynecology found 74,000 pregnant women who received a flu shot, in any trimester, were no more likely to experience pregnancy complications. Rates of severe morning sickness, urinary tract infections, high blood pressure and other complications in the 2010-11 flu season were compared. The researchers looked at incidence of these problems 42 days after vaccination and through to the birth.

"This is the single largest and best and most reliable safety study we have to date. We didn't have concerns about [the safety of the vaccine], and this puts the icing on the cake," Vanderbilt University Medical School chair Dr. William Schaffner told Reuters. The finding has strengthened convictions that the benefits of receiving the flu vaccine outweigh the risks. Catching the flu during pregnancy increases the risk of death, respiratory disease requiring hospitalization and premature labor and delivery.

Flu vaccines cut the risk of these events, while also preparing babies for the first months outside the womb. Previous studies have shown the vaccine's protection passes across the placenta to give babies some defenses against the virus. The protection can help shield babies from flu in their first 6 months, at which point childhood vaccination programs begin. Schaffner said this favorable risk-reward ratio means "there should be no hesitation for women getting the vaccine."
