Researchers found that H1N1 flu vaccine during pregnancy is not related to birth defects. The study was made by scientists from the Karolinska Institute, Stockholm. They wanted to find out if there are any risks of congenital malformation in pregnant women who received the vaccine. Moreover, they took into consideration the familial factors.
Researchers used data from 49 983 mothers who gave birth between Oct 1, 2009, and Oct. 1, 2011. Those women received the vaccine during their pregnancy. They compared the exposed offspring with the unexposed siblings. It seems there were no big differences between those two. The risk for vaccination during the first trimester was 0.16% for the exposed mothers and 0.1% for those who were not exposed.
Researchers said that there was no connection between the vaccine and congenital malformation, for mothers exposed to the treatment. However, there could still be some danger for some birth defects, so future mothers should really pay attention and talk to a doctor before getting the vaccine. The study was possible due to funding by Swedish Research Council.
The U.S. Centers for Disease Control and Prevention advise the pregnant women to get the vaccine since they are more vulnerable to complications than other people. It is very important for the future mothers to have their vaccines in the first semester of pregnancy. That is the period when organ development begins and the child is vulnerable to a birth defect.
Researchers from the United States seem to have the same opinion as for the authors of the study. There is no evidence that vaccinated pregnant women have a higher risk of congenital malformations. The United States is the largest market for H1N1 vaccine. Europe is also having major shares of this market.
H1N1 influenza is an infectious disease, that can cause a lot of problems for those who do not get the vaccine. The vaccine market developed because there were a lot of people infected with this virus and needed help. According to this new study, pregnant women have nothing to worry because the vaccine is safe. You will feel good and your baby will not have any birth defects related to it.
The World Health Organization declared the new strain of H1N1 as a pandemic. The virus was spread in the whole world and caused thousands of deaths. Even though in 2010 the pandemic was over, H1N1 is still a dangerous virus.
