Which Flu Vaccine For Pregnant

Safety And Side Effects

Flu vaccine for pregnant women

Seasonal flu vaccination has been recommended in pregnancy for several years in many countries. An increasing number of studies have shown it to be safe in all stages of pregnancy, including the first three months, and to have an important reduction in serious complications for the mother and baby. Read the abstracts of a US study from 2009 and a US study from 2012.

Another US study published in 2017 studied the effects of flu vaccination in the first three months of pregnancy. It looked at birth defects in over 52,000 babies who had been exposed to the flu vaccine in the first three months of pregnancy. By comparing this group with over 370,000 babies who had not been exposed to the flu vaccine, the study showed that having the flu vaccine in early pregnancy was not associated with an increased risk of birth defects.

The most commonly reported side effects of flu vaccines are:

  • pain, swelling, bruising, hardness or redness at the injection site
  • slightly raised temperature

How Do I Get The Flu Vaccine

Contact your midwife or GP surgery to find out where you can get the flu vaccine. It’s a good idea to get vaccinated as soon as possible after the vaccine becomes available in September.

In some areas, midwives can give the flu vaccine at the antenatal clinic. In others, you will need an appointment at a GP surgery.

Some community pharmacies now offer the flu vaccine on the NHS.

Northern Hemisphere Influenza Season

The composition of trivalent virus vaccines for use in the 2017â2018 Northern Hemisphere influenza season recommended by the Advisory Committee on Immunization Practices on August 25, 2017, was:

  • an A/Michigan/45/2015 pdm09âlike virus
  • an A/Hong Kong/4801/2014 -like virus
  • a B/Brisbane/60/2008âlike virus

In addition to these components, quadrivalent vaccines will also include a B/Phuket/3073/2013âlike virus .

In California, some emergency systems were strained by a spike in H3N2 flu cases. In addition, some areas experienced local shortages of oseltamivir. The severity of the flu season seemed somewhat comparable to the 2009â10 swine flu outbreak. A February 2018 CDC interim report estimated the vaccine effectiveness to be 25% against H3N2, 67% against H1N1, and 42% against influenza B.

One and done doesnt apply when it comes to vaccines that are recommended for pregnant women. The amount of antibodies that you have in your body after getting vaccinated decreases over time.

So, make sure you give baby number 2 the greatest number of protective antibodies and the best disease protection possible by getting your whooping cough vaccine each time you are pregnant. You should also get a flu shot every influenza season.

About The Influenza Vaccine

Studies show that the influenza vaccine provides just as much protection for pregnant women as for other healthy adults. On average, it provides protection against influenza for 60 % of those who are vaccinated. This means that many who have been vaccinated may still be infected, but there are many indications that they have a milder disease course than if they had not been vaccinated.

The influenza vaccine recommended for pregnant women is given as a single dose and contains only fragments of the influenza virus, salts and water. The vaccine does not cause influenza disease.

The influenza vaccine does not protect against coronavirus or other viruses and bacteria that cause influenza-like symptoms.

Whats The Big Deal About Getting The Flu When Im Pregnant

The pregnant you is not the same as the non-pregnant you, especially when it comes to your immune system.

In general, your immune system is dialed down a bit in pregnancy. But interestingly enough, your pregnant immune system may actually respond more intensely in certain situations. And how you respond to the influenza virus is one of those situations. It is thought that this altered immune response, along with changes in how your heart and lungs work, are why pregnant women who get the flu often have much more severe symptoms, serious complications, and can even die from the infection.

There is also some evidence that having the flu in the first several weeks of pregnancy might be associated with an increased risk of your baby being born with certain birth defects.

Key Facts About The Flu Vaccine For Pregnant Women

The flu vaccine is available between September and January or February every year, and it is recommended that pregnant women get it as early as possible during the season.

There is strong evidence that pregnant women have a much higher risk of serious illness as a result of flu, compared with the general population. The risks are highest in the last three months of pregnancy.

Vaccination against flu reduces the risk of complications caused by the virus for women and babies. Serious complications of flu include bronchitis, pneumonia, septic shock , meningitis and encephalitis .

There is also strong evidence that catching flu in pregnancy has an effect on the unborn baby. Babies born to women who have had flu are up to four times more likely to be born prematurely and to have a low birth weight. This may be because flu infection produces an inflammatory response in the body which can trigger premature labour. Flu in pregnancy can even lead to stillbirth or death in the first week of life.

Can Pregnant People With Egg Allergies Get Vaccinated

Flu vaccines during pregnancy

Most people who have an allergy to eggs can get vaccinated, with some additional safety measures. A person with severe allergy to any vaccine component, including egg protein, should not get the shot, even if they are pregnant. Pregnant people should tell the person giving the shots if they have any severe allergies or if they have ever had a severe allergic reaction following a flu shot.

People with egg allergies can receive any licensed, recommended age-appropriate influenza vaccine that is otherwise appropriate. People who have a history of severe egg allergy should be vaccinated in a medical setting, supervised by a health care provider who is able to recognize and manage severe allergic reactions. Two completely egg-free flu vaccine options are available: quadrivalent recombinant vaccine and quadrivalent cell-based vaccine.

How Effective Is The Flu Vaccination In Pregnancy Programme

Who Needs a Flu Vaccine and When

The flu vaccine works better in some years than others .

US studies of the H1N1 pandemic in 2009 found that pregnant women were four times as likely to develop serious illness and up to five times as likely to be admitted to hospital, compared with the general population. As a result of the evidence from this pandemic, pregnant women were added to the list of groups considered to be at higher risk from seasonal flu.

In the UK between 2009 and 2012, flu was the cause of death for 36 women who died during pregnancy or shortly afterwards. It is estimated that half of these deaths could have been prevented by flu vaccination. See the 2014 summary report from MBRRACE-UK .

Recent research covering almost 20,000 pregnant women over six years in the United States, Australia, Israel, and Canada, showed that the flu vaccine provided a 40% reduction in hospitalisations from flu. The PREVENT study looked at data between 2010 and 2016 to identify flu-related hospital admissions .

Studies have shown that women who have been vaccinated against flu are less likely to give birth prematurely, and less likely to have a low-birthweight baby . Other studies have shown that women who have the flu vaccine while pregnant are less likely to experience stillbirth .

Flu vaccination in pregnancy also means that flu antibodies are transferred through the placenta to the baby. This gives the baby some protection against flu for the first few months of life.

So What About The Research Linking Flu Shots And Miscarriage

Many studies over several years have shown the relative safety of the flu vaccine in pregnancy. Although studies involving women in the first trimester of pregnancy are limited, those studies that did include women vaccinated in the first trimester of pregnancy did not show an association with miscarriage.

In a recent study, the data suggest an association between getting a flu shot and having a miscarriage within 28 days of the vaccine, especially in those women who were also vaccinated against the H1N1 strain in the prior year.

These results are surprising. One potential explanation is the specific inflammatory response triggered by the H1N1 vaccine, with a repeat vaccination causing an even more significant response to occur. As noted by the authors of a commentary published with the original article, One important takeaway message from this study is that seasonal vaccine formulations are not all the same.

Expert panels including the American Congress of Obstetricians and Gynecologists have not changed their opinion based on these study results, noting that the study included only a small number of women, and those results are not outweighed by the significant amount of existing data supporting flu vaccine safety. The current guidelines that the flu vaccine is strongly recommended in pregnancy, and is safe to be given in any trimester, remain unchanged.
