Can You Get The Flu Shot When You Are Pregnant? A Comprehensive Guide
Yes, absolutely! Getting the flu shot while pregnant is not only safe but is highly recommended to protect both the mother and her developing baby.
Why Flu Shots Are Critical During Pregnancy
Pregnancy significantly alters a woman’s immune system, making her more susceptible to severe complications from the influenza virus (the flu). These complications can include pneumonia, bronchitis, sinus infections, and even hospitalization. Moreover, studies have shown a link between maternal flu infection and adverse pregnancy outcomes such as premature labor and delivery. Can You Get The Flu Shot When You Are Pregnant? You certainly can, and doing so offers significant protection.
The Benefits of Flu Vaccination During Pregnancy
Vaccination provides a two-fold benefit:
- Protects the Mother: The flu shot significantly reduces the risk of the pregnant woman contracting the flu, lessening the chance of severe illness and hospitalization.
- Protects the Baby: Antibodies produced by the mother after vaccination are transferred to the baby through the placenta. These antibodies provide crucial protection against the flu in the baby’s first few months of life when they are too young to be vaccinated themselves.
This passive immunity is particularly important because infants are at a higher risk of developing serious flu-related complications.
Types of Flu Vaccines Recommended During Pregnancy
The CDC (Centers for Disease Control and Prevention) recommends that pregnant women receive the inactivated influenza vaccine (IIV), commonly known as the flu shot. This vaccine contains killed flu viruses and cannot cause the flu.
Important Note: The live attenuated influenza vaccine (LAIV), commonly known as the nasal spray flu vaccine, is not recommended for pregnant women.
| Vaccine Type | Composition | Recommendation During Pregnancy |
|---|---|---|
| Inactivated Influenza Vaccine (IIV) | Killed flu viruses | Recommended |
| Live Attenuated Influenza Vaccine (LAIV) | Weakened live flu viruses | Not Recommended |
Understanding Flu Shot Safety During Pregnancy
Extensive research and decades of experience have consistently demonstrated the safety of flu shots during pregnancy. The CDC, the American College of Obstetricians and Gynecologists (ACOG), and the American Academy of Pediatrics (AAP) all strongly recommend flu vaccination for all pregnant women, regardless of trimester.
The Best Time to Get Vaccinated
Ideally, pregnant women should receive the flu shot as soon as it becomes available, usually in early fall (September or October). However, vaccination can still be beneficial at any point during flu season, which typically lasts from October to May. Can You Get The Flu Shot When You Are Pregnant? Yes, even if you are already in your second or third trimester, it is never too late to get vaccinated.
Addressing Common Concerns and Misconceptions
One common misconception is that the flu shot can cause the flu. This is not true. The inactivated vaccine contains killed viruses and cannot cause illness. Some people may experience mild side effects such as soreness, redness, or swelling at the injection site, or mild muscle aches or a low-grade fever. These side effects are usually mild and resolve within a day or two. Another concern is the presence of thimerosal, a mercury-based preservative, in some flu vaccines. Thimerosal is used in multi-dose vials to prevent contamination. Single-dose vials are available that do not contain thimerosal. Even if a multi-dose vial is used, the amount of thimerosal is very low and considered safe by experts.
Steps to Getting Your Flu Shot
- Consult with your healthcare provider: Discuss your vaccination options and address any concerns you may have.
- Find a vaccination site: Flu shots are widely available at doctor’s offices, pharmacies, and health clinics.
- Schedule an appointment or walk in: Many locations offer walk-in vaccinations, while others require an appointment.
- Receive your vaccination: The flu shot is administered as an intramuscular injection, typically in the arm.
- Monitor for any side effects: As mentioned earlier, mild side effects are possible, but severe reactions are rare.

Frequently Asked Questions (FAQs)
What happens if I get the flu while pregnant?
Contracting the flu during pregnancy can lead to serious complications, including pneumonia, bronchitis, and even hospitalization. It can also increase the risk of premature labor and delivery, potentially affecting the health of both mother and baby.
Are there any risks associated with getting the flu shot during pregnancy?
The flu shot is considered very safe during pregnancy. The most common side effects are mild and temporary, such as soreness at the injection site or a low-grade fever. Severe reactions are extremely rare.
Can the flu shot give me the flu?
No, the inactivated influenza vaccine contains killed viruses and cannot cause the flu. You may experience mild side effects, but these are not the same as having the flu.
Is it safe to get the flu shot in my first trimester?
Yes, it is safe and recommended to get the flu shot in any trimester of pregnancy. There is no evidence to suggest that vaccination in the first trimester poses any risks to the developing baby.
What if I have an egg allergy?
Most flu vaccines are manufactured using egg-based technology. However, people with egg allergies can still usually receive the flu shot. The CDC recommends that individuals with severe egg allergies receive the vaccine in a medical setting and be monitored for 30 minutes after vaccination. There are also some egg-free flu vaccines available. Discuss your allergy with your doctor to determine the best option.
Does the flu shot protect against COVID-19?
No, the flu shot specifically protects against influenza viruses. It does not protect against COVID-19. Vaccination against COVID-19 is also recommended during pregnancy.
How long does it take for the flu shot to become effective?
It typically takes about two weeks after vaccination for your body to develop the antibodies needed to protect against the flu.
If I got the flu shot last year, do I need to get it again this year?
Yes, the flu viruses that circulate each year can change, so it is important to get vaccinated every year to ensure you are protected against the current strains.
Can I get the flu shot and other vaccines at the same time?
Generally, it is safe to receive the flu shot and other vaccines, such as the Tdap vaccine (which protects against tetanus, diphtheria, and pertussis), at the same time. However, always consult with your healthcare provider to determine the best vaccination schedule for you.
What if I am breastfeeding?
The flu shot is safe and recommended for breastfeeding mothers. Vaccination during breastfeeding can provide further protection to the baby through breast milk.
Are there any situations where I shouldn’t get the flu shot?
There are very few contraindications to the flu shot. The most common reason to avoid vaccination is a severe allergic reaction to a previous flu vaccine. Discuss any medical conditions or concerns with your healthcare provider.
Where can I get the flu shot?
Flu shots are widely available at doctor’s offices, pharmacies, health clinics, and even some workplaces. Use the CDC’s VaccineFinder tool (vaccines.gov) to find a location near you.
