Pregnancy + Flu = Not a Good Equation

Posted September 27, 2010. | Filed under Flu Shots, Flu Tips, Pediatric, Risk/Priority Groups

Most people would agree- the flu is not fun. Period. High fevers, chills, headaches, extreme exhaustion, coughing, sore throat, runny or stuffy nose, and muscle aches….yes… these symptoms of the flu do not add up to a good time. They can be even more intense and dangerous to you if you are expecting this flu season.

Why is the flu more dangerous for pregnant women?

While catching the flu during pregnancy rarely causes birth defects, pregnancy puts extra stress on your heart and lungs and can also affect your immune system. These factors increase the risk not only of getting the flu but of developing serious complications from the flu, such as pneumonia and respiratory distress[i]. As a result, flu complications may lead to miscarriage, premature labor or other pregnancy complications[ii].

What’s the best way to prevent the flu during pregnancy?

To prevent the flu, get vaccinated. A flu vaccine is the number one way to prevent the flu. Flu season can begin as early as October and last as late as May. October or November is the best time to get vaccinated, but if for some reason you are not able to receive your vaccine during that time period, getting vaccinated in December is still better than not getting vaccinated at all.

Is the flu shot safe during pregnancy or if I’ve recently given birth?

The Centers for Disease Control and Prevention (CDC), The American Academy of Family Physicians (AAFP), American Academy of Pediatrics (AAP), American Medical Association (AMA), American Nurses Association (ANA), March of Dimes, and several other professional organizations are recommending flu shots for pregnant and postpartum patients during flu season — typically November through January or even later. The only exception is pregnant women who are allergic to eggs, since egg products are used to make the vaccine. When you get your flu shot, be sure to request the injectable flu shot and not the nasal spray vaccine. The flu shot is made from an inactive virus, so it’s safe for both mother and baby. The nasal spray vaccine is made from a live attenuated virus, and is currently contraindicated for pregnant women. While the flu shot does not contain the live virus and cannot give you the flu, some women may experience fatigue and muscle aches due to their immune system responding to the vaccine. In addition, the flu shot is also safe while breastfeeding. It cannot cause you or your nursing baby to get sick.

Why should I get a flu shot?

The main reason to get your shot, as mentioned earlier, is that you don’t want to get the flu while you are pregnant as there would be a higher risk of flu complications, both for yourself and your baby. Also, by getting your flu shot, you will decrease the chances your new baby will get sick once he or she is born. This is because your baby will experience the benefits of the antibodies from the vaccine that your body creates and transfers, providing him or her with added protection from getting the flu. This is important because children under six months of age can not get a flu shot.

After all, if you don’t get your flu shot, there is a higher possibility that you can get sick with the flu and then pass the infection on to your new baby. For this same reason, everyone in your household, and anyone who may care for a newborn, should also be vaccinated. Remember that anyone over 6 months of age can get a flu shot each year. By getting vaccinated, your entire family will be able to help protect your unborn baby because he or she will be too young to receive the vaccine at birth.  This works because of the concept of herd immunity. Herd immunity basically means that if most of the people you are surrounded by are immune to an infection and unable to get sick, then there are fewer people around who can infect you, making it less likely for disease to spread, even if you aren’t immune to the infection yourself[iii].

Are there any other steps I can take to avoid getting the flu?

Yes. In addition to getting the flu shot, there are several additional steps you can take to protect yourself from the flu this season. Learn how you can help stop the spread of germs.

What do I do if I think I have the flu?

If you are pregnant and experiencing flu-like symptoms, pay attention to your body. Not all over the counter cold and flu medications are safe to take during pregnancy, so before taking anything, it is best to call your health care provider right away.
