When Not To Get The Flu Shot
There are a few instances where a pregnant woman should not receive the vaccination. As with anyone, you should not get the flu shot if you are suffering from an illness of any sort, since your immune system is already compromised. Its fine to wait until you are well to get the flu shot.
And despite the strong recommendation to get the flu shot, pregnant women are advised against receiving the nasal spray version of the vaccine. Manglani says, the nasal spray vaccine is never approved for use during pregnancy. This is because its a live attenuated vaccine. Live vaccines are not approved in pregnancy because there is a possible risk to baby. In pregnancy, a woman is immunocompromised and could theoretically get the flu from the live vaccine.
Finally, since the flu vaccines are grown in chicken eggs, you should talk to your doctor if you have an egg allergy of any sort.
What Do I Do If I Have Flu Symptoms
Its always best to call your doctor or clinic if youre pregnant and develop flu-like symptoms such as fever, body aches, cough and headache. Its advisable to do this even if youve been vaccinated against the flu. There are medications your doctor can recommend that are safe for use during pregnancy however, they work best if commenced within a couple of days of symptoms starting.
Why Are Pregnant Women At Higher Risk For Serious Flu Illness
Youve probably heard that the flu can be dangerous for older people, infants and people with health conditions. But you may not know that pregnant women are also at higher risk for complications like pneumonia. Why? Because changes to your body make it easier for you to get sick.
Even if you feel healthy and strong while pregnant, pregnancy affects your immune system, heart and lungs. This can make you more susceptible to the flu and can put you at higher risk of more serious illness.
In addition to getting a flu shot, you can take extra steps to stay as healthy as possible, including washing your hands regularly, covering your cough, and keeping your immune system strong by , eating well, and practicing good health habits.

Do Flu Vaccines Cause Any Side Effects
Like any medical product, vaccines can cause side effects. Side effects of the flu vaccine are generally mild and go away on their own within a few days.
Common side effects from the flu shot include:
- Soreness, redness, and/or swelling from the shot
- Headache
- Muscle aches
The flu shot, like other injections, can occasionally cause fainting.
Some studies have found a possible small association of injectable flu vaccine with Guillain-Barré syndrome . Overall, these studies estimated the risk for GBS after vaccination as fewer than 1 or 2 cases of GBS per one million people vaccinated. Other studies have not found any association. GBS also, rarely, occurs after flu illness. Even though GBS following flu illness is rare, GBS is more common following flu illness than following flu vaccination. GBS has not been associated with the nasal spray vaccine.
How Serious Is The Flu If I Am Pregnant

How Is The Safety Of Flu Vaccines In Pregnant People Monitored
CDC and FDA conduct ongoing safety monitoring of vaccines licensed for use in the United States.
CDC and FDA monitor flu vaccine safety during pregnancy during each flu season using the Vaccine Adverse Event Reporting System : An early warning system that helps CDC and FDA monitor health concerns following vaccination. Anyone can report possible vaccine side effects to VAERS. Generally, VAERS reports cannot determine if a health concern that arises after vaccination was caused by a vaccine, but these reports can help indicate if further investigations are needed.
In addition CDC conducts research studies in the Vaccine Safety Datalink : A collaboration between CDC and nine health care organizations which allows ongoing monitoring and proactive searches of vaccine-related data.
Why You Should Get The Flu Vaccine
The flu vaccine can protect your baby from flu until they are 6 months old. It can also prevent you from getting flu and passing it on to your baby.
Dr Maeve Eogan, consultant obstetrician and gynaecologist, talks about why you should get the flu vaccine if you are pregnant.

What Are The Benefits Of Having The Flu Vaccine During Pregnancy
There are three main benefits to being vaccinated against the flu duringpregnancy:
The vaccine protects you and your unborn baby against the flu. Theeffectiveness of the flu vaccine varies from year to year depending onvarious factors, including how well the vaccine is matched to seasonalinfluenza strains. But research shows individuals who have the vaccine and still contract the flu are less likely to develop severe consequences. Research is currently underway to developa better vaccine that is more broadly effective and doesnt have to beadministered every season. But at the moment, the current seasonalvaccine is the best protection we have for a mum and her unborn baby.
Your baby is protected for the first few months after being born. Babiesyounger than six months are at increased risk of respiratory illnessescompared to babies of mothers who had been vaccinated against the flu.Infants cannot receive the flu shot until they are six months old making thisa particularly vulnerable time. When the flu vaccine is given in pregnancy, maternal antibodies are transferredthrough the placenta to the unborn baby, protecting the infant in their first few months of life.
The flu vaccine may also protect you against whooping cough. Recent research has found women are less likely to get whooping cough during pregnancy if theyve had the flu shot. The vaccine prevented many mums from contracting the flu, which subsequently protected them from a whooping cough coinfection.

Injection Vs Nasal Spray Vaccine
The influenza vaccine can be delivered as either an injection or as a nasal spray.
The flu shot can come in a variety of forms that protect against three or four influenza strains. Although no type of flu shot is recommended over others, you should speak to your doctor about which one is best for you.

What To Do If Youre On The Fence About Getting Vaccinated
Getting the flu shot during any trimester of pregnancy is reasonable and safe, and being vaccinated against the flu in the first trimester will not put your baby at risk. But if youre nervous about getting the flu shot during the first trimester, dont refuse to be vaccinated. Just hold off until after you reach 20 weeks of pregnancy. The Vaccine study reported there was no increased risk after 20 weeks of pregnancy. You might not be as fully protected from the flu, which can lead to serious complications including hospitalization and even death in pregnant women, but your baby will still get the antibody benefit.
The key takeaway for women is that scientific research studies have never proven a cause/effect relationship between the flu vaccine and miscarriage. In fact, showed no link between miscarriage rates and maternal flu vaccination using clinical data, and an found no increased risk between maternal flu vaccination and birth defects in babies. Even the study published in Vaccine states that the data retrieved demonstrate an association, not a cause/effect relationship, between flu shots and miscarriage.

Misconceptions About Flu Vaccines
Can a flu vaccine give you flu?
No, flu vaccines cannot cause flu illness. Flu vaccines given with a needle are made with either inactivated viruses, or with only a single protein from the flu virus. The nasal spray vaccine contains live viruses that are attenuated so that they will not cause illness.
Are any of the available flu vaccines recommended over the others?
Yes, for some people. For the 2022-2023 flu season, there are three flu vaccines that are preferentially recommended for people 65 years and older. These are Fluzone High-DoseQuadrivalent vaccine, Flublok Quadrivalent recombinantflu vaccine or Fluad Quadrivalent adjuvanted flu vaccine. On June 22, 2022, CDCs Advisory Committee on Immunization Practices voted unanimously to preferentially recommend these vaccines overstandard-dose unadjuvanted flu vaccines. This recommendation was based on a review of available studies which suggests that, in this age group, these vaccines are potentially more effective than standard dose unadjuvanted flu vaccines. There is no preferential recommendation for people younger than 65 years.
What if a preferentially recommended flu vaccine is not available?
If none of the three preferentially recommended flu vaccines for people 65 and older is available at the time of administration, people in this age group should get any other age-appropriate flu vaccine instead.
Is it better to get sick with flu than to get a flu vaccine?
Do I really need a flu vaccine every year?
To 48 Hours After Vaccination
Once these body-wide side effects set in, they can last for 12 hours or more. Experts say these side effects should all stop within 24 to 48 hours after your shot, though you may still have some slight fatigue or arm soreness after that.
Mullane says its best to avoid important events or take on key tasks the day after your vaccination if youre concerned about the side effects. Thats because your vaccine appointment and the window for peak symptoms arent likely to happen at the same time. Most side effects come later.
Its OK to take an anti-inflammatory medication like Tylenol or ibuprofen to relieve any symptoms. But Mullane says not to take it before the shot, as it can interfere with your immune response.

What If Youre Not Pregnant Yet Can You Get Pregnant After Your Flu Shot
You absolutely can. The American College of Obstetrics and Gynecology recommends that people who are trying to get pregnant get vaccinated. People who get the flu while pregnant are at a higher risk for serious illness and complications. You will have full protection 2 weeks after immunization.

What Is A Flu Shot

Influenza vaccination protects you against the seasonal flu, a contagious respiratory illness.
If you end up with the flu, you might experience symptoms like fever, cough, body aches, and a sore throat. The flu is never fun but it can be a lot more serious if you are very old, very young, have certain medical conditions, or are pregnant.
There are two main types of flu vaccine: an injection and a nasal spray. Making sure you get one of these each year is the best way to avoid becoming infected. Getting the shot annually is important because the virus changes and develops, so researchers update the vaccine composition.
In the United States, flu season begins around October and peaks between December and February, so you should schedule your vaccination as early as October 1.
