According to CDC reports, overall flu activity continues to be high. In mid-January, 35 states are reporting widespread flu activity, and 10 flu-related deaths of children have been confirmed.

Now that we are moving into peak flu season, I want to remind every pregnant woman to go get her flu shot.  And it’s not too late! Getting a flu vaccination is the best way to protect yourself and your baby from the flu.

CDC surveillance data has shown that the predominant flu strain this year is H1N1, the same that emerged in 2009 to cause a pandemic. Since this strain causes more severe illness in children and young adults, compared to older adults, young women and children are at increased risk.  So it is even more important to be vaccinated if you are pregnant. The flu vaccine is safe and effective during pregnancy.

In addition to getting the vaccine, here’s what you should know about flu and pregnancy:


Health complications from the flu, such as pneumonia, can be serious and even deadly, especially if you’re pregnant. Pregnant women who get the flu are more likely than women who don’t get it to have preterm labor and premature birth. Prematurity can cause serious lifelong health problems for your baby.

The flu can be harmful during pregnancy because when you’re pregnant, your immune system isn’t as quick to respond to illnesses as it was before pregnancy. Your body naturally lowers the immune system’s ability to protect you and respond to illnesses so that it can welcome your growing baby. But a lowered immune system means you’re more likely to catch illnesses like the flu.

Another reason the flu can be harmful during pregnancy is that your heart and lungs are already working hard to keep up with the demands of the growing fetus.  They can’t always keep up with the stress placed on them by influenza infection.  As a result, pregnant women are more likely to be hospitalized in intensive care and more likely to die from complications of flu.


If you think you might have the flu, call your health care provider right away.

Your doctor can give you antiviral medicines to help fight the flu, but you need a prescription for them. So call your doctor as soon as you have symptoms and are concerned.  It’s important to start these medicines right away.

The Centers for Disease Control and Prevention (CDC) recommends two antiviral medicines for flu. Talk to your provider about which medicine is right for you:

1.     Oseltamivir (Tamiflu)
2.     Zanamivir (Relenza)

Fever is a symptom of the flu that can last a week or longer. A fever caused by flu infection or other infections early in pregnancy can lead to birth defects in a fetus. Pregnant women who get a fever should call their doctor as soon as possible. You can ask your health care provider if you can take acetaminophen (Tylenol®) to bring down your fever.

And remember: It’s not too late to get the flu vaccine. It is offered in many locations, including doctor’s offices, clinics, health departments, and pharmacies. Visit the HealthMap Vaccine Finder to locate where you can get a flu shot.

    This is so important. Thank you for making people aware of the risks. Many people don’t realize that not only is the flu vaccine safe for pregnant women, but it is also the best way to protect pregnant women and their babies from the harmful effects of the flu!

    I think women need to be more educated about having the flu during pregnancy, especially if it can cause premature birth. My daughter was born at 23 weeks last year for different reasons and I do not wish it on anyone. See out story at

    I received the flu shot while pregnant and I had the flu for 2 months after! I finally has to do a detox (juicing) and the flu was gone I think clean eating and a healthy life style is the answer. Not a Flu shot! Your body can build immunity on its own.
