Is it dangerous to catch the flu? What are the risks to the pregnant woman to the fetus? Can I get vaccinated against the flu during pregnancy? Every pregnant woman is asking these questions during an epidemic influenza. What should I know?
Influenza: pregnancy is a risk period
Each year, the government stressed the importance of immunization of persons 65 years and older and people with a long-term illness. For populations at risk, the vaccine against influenza is supported 100% by insurance. But there are other risk populations, including pregnant women. This is precisely why health insurance has expanded (end December 2010) of free vaccine to all pregnant women.
What are the risks to pregnant women and fetuses?
Vaccination against influenza is recommended even for pregnant women at risk of developing complications. The effects of influenza virus during pregnancy and the fetus are difficult to study. But according to one study, the flu in late pregnancy multiplies by 4.7 the risk of being hospitalized for cardiorespiratory complications. Some studies also show an increased risk of fetal infection with particular cardiac manifestations. However, no congenital anomaly, or any influence on birth weight were associated with influenza infection. In the new-born now, we know that infection can be fatal and the risk of hospitalization for influenza infection is twice between 0 and 6 months compared to older children.
If this picture may seem scary to some (s), note that these complications are rare, particularly among pregnant women who have no particular risk. But why take risks when there is a vaccine? Finally, let us not forget that flu is the largest provider of mowing layer. Ultimately, it is perfectly logical that the vaccine is free for pregnant women!
To date, no adverse effects of vaccination have been reported, both in pregnancy that the fetus or the newborn. Some studies have even followed the children until the age of 7 years.
Meanwhile, pregnant women are more frequent contact with young children. But if the flu virus occurs annually in the general population 10% of adults, it reaches up to 30% of children (and yes, we often forget that children are prime targets of the virus and then contribute greatly to the spread of the virus). Thus an estimated 5 to 22% the number of pregnant women affected by HIV each year.
In conclusion, it is useful for pregnant women to get vaccinated, and especially since they are in contact with children.
For those who are not immunized, they may act as a barrier to the virus by vaccinating children living at home.
