What Vaccines Are Safe For Pregnancy

Can You Get A Covid

Are coronavirus vaccines safe for pregnant women?

The CDC is learning more about how safe and effective the COVID-19 vaccine is when its given at the same time as other vaccines, such as the flu or Tdap vaccine. The CDC currently recommends:

  • That you wait at least 14 days after getting the COVID-19 vaccine to get any other vaccine.
  • That you wait at least 14 days before getting a COVID-19 vaccine after getting other vaccines.
  • That you complete your vaccinations on schedule even if youve gotten a COVID-19 vaccine.

Are Vaccines Safe During Pregnancy

Certain vaccines are safe and recommended for women before, during, and after pregnancy to help keep them and their babies healthy. The antibodies mothers develop in response to these vaccines not only protect them, but also cross the placenta and help protect their babies from serious diseases early in life. Vaccinating during pregnancy also helps protect a mother from getting a serious disease and then giving it to her newborn.

Vaccine Safety Before During And After Pregnancy

Its important to know that the Tdap and flu vaccines are safe for a pregnant person and their baby. Likewise, the limited information collected for COVID-19 vaccines given to pregnant people have not identified any safety concerns for them or their babies.

It is important to get MMR before becoming pregnant to reduce the risk of becoming infected with rubella which can pass on to the unborn child, causing Congenital Rubella Syndrome . CRS can cause severe birth defects and neurodevelopmental problems. Even though MMR is a safe and effective vaccine, there is a theoretical risk to the baby. This is because it is a live vaccine, meaning it contains a weakened version of the living viruses.

  • Live vaccines are generally not recommended during pregnancy.
  • If a pregnant person did not get MMR as a child, she should get the vaccine before pregnancy.

Maternal Vaccinations To Prevent Risks Of Vertical Transmission Of Infection From Mother To Her Fetus

Vaccination during pregnancy is warranted, if the vaccination can prevent maternal infections and the risks of vertical transmission of infection to the unborn fetus, provided the vaccine is unlikely to cause maternal or fetal harm.

For bacterial infections that are transmitted vertically from mother to fetus, the transmission can be prevented by adequate and timely treatment of mother with antibiotics, before permanent harm ensues to the fetus or the neonate. These include infections like syphilis, group B streptococcus , chlamydia, and gonorrhea.

However many viral infections acquired by mother can be transmitted to the fetus and to the newborn, during pregnancy, peripartum, and subsequently during breast feeding. These viral infections include hepatitis virus subtypes A, B, C, and E, human papilloma virus, and HIV infections.

Hepatitis A vaccine , inactivated

It is indicated in woman with high risk of acquiring hepatitis A infection. This includes intravenous drug users, having poor hygiene, staying near sewage or endemic areas, having chronic liver conditions or regularly requiring clotting factor concentrates.

Hepatitis B vaccine

HBV vaccination first became available in 1980. A combination of HBV vaccine and hepatitis B immune globulin given within the first 12 h after birth to the neonate, gives the greatest long-term immunity in 8595% of cases .

Increased Risk Of Serious Covid

Safety guidelines on coronavirus vaccination for pregnant moms too ...

Due to the physical changes involved in pregnancy, it can place a burden on the body and pose a risk factor for a serious COVID-19 infection. This increased risk exists for all pregnant women, not just those with pre-existing illnesses or conditions such as obesity, chronic hypertension and diabetes. The risk further increases with age.Data contained in studies indicates that a coronavirus infection is more likely to be severe in pregnant women than in others who become infected. A pregnant woman with a coronavirus infection is likely to be hospitalised and require intensive care. Around one in ten pregnant women who are hospitalised with COVID-19 symptoms require intensive care.

Wolfgang Heinrich, Gynaecologist and Director of the Maternity Clinic at the Berlin Charité, describes a typical working day:

What were seeing more and more are pregnant women with life-threatening illnesses who lose their babies or have premature births and women who will suffer permanent effects if they survive. For a woman who becomes ill during pregnancy the risk of dying before the birth, during the birth or in the first few weeks after delivery is 50 times greater.

How Many Doses Have Been Donated By Each Country

These charts show the cumulative number of doses donated to the COVAX initiative by different countries, broken down by whether the donations have only been announced, actually donated, or delivered to the recipients. This is only available for a select number of countries for which the COVID-19 Task Force reports the necessary data.

The three following charts show the number of doses donated, adjusted for:

  • The population of the donating country
  • The GDP of the donating country
  • The number of doses administered by the donating country to its own population.
  • COVID-19 Vaccines Global Access

    COVAX is a worldwide initiative aimed at equitable access to COVID-19 vaccines directed by Gavi, the Vaccine Alliance, the Coalition for Epidemic Preparedness Innovations , and the World Health Organization . COVAX coordinates international resources to enable low-to-middle-income countries equitable access to COVID-19 tests, therapies, and vaccines.

    What Vaccines Should You Get After Delivery

    Now is the time to catch up on any vaccines you may have been unable to get during pregnancy or before becoming pregnant, such as the MMR and chickenpox vaccines. Moms who are breastfeeding can get vaccinated according to a normal adult vaccination schedule.

    As mentioned above, if youre due for a Td booster and didnt get one during pregnancy, the latest recommendation is to get Tdap, which includes pertussis, also known as whooping cough. Women younger than 26 should also consider getting the HPV vaccine that helps protect against cervical cancer. The shot isnt recommended during pregnancy because studies havent yet determined its safety for a developing baby.

    Will The Vaccine Cause Infertility Or Damage To The Placenta

    There is also no evidence that the COVID-19 vaccine would reduce your natural fertility or harm the placenta or fetus. While the COVID-19 vaccine is new, the mechanism of action of this mRNA vaccine and existing safety data provide reassurance regarding the safety of COVID-19 mRNA vaccines during pregnancy. A recent study published in The American Society for Reproductive Medicine s Fertility & Sterility found no difference in implantation rates in patients with previous vaccination, previous infection, and no previous vaccination or infection.

    The president of the ASRM states that no matter where you are in the family-building process, the COVID-19 vaccine is safe and saves lives.

    Risks Related To Covid

    VERIFY: Are COVID-19 vaccines safe for pregnant women?

    COVID-19 infection during pregnancy increases the risk of medical complications and death.

    If you contract COVID-19 during your pregnancy, you are:

    • more likely to be hospitalized
    • more likely to be admitted to the intensive care unit
    • more likely to suffer from severe illness
    • more likely to require ventilation/life support breathing

    In addition, COVID-19 infection in pregnancy significantly increases the risk of:

    • stillbirth
    • caesarean delivery
    • low birth weight

    There is also an increased risk that the baby will need to be admitted to the neonatal intensive care.

    Vaccination Has No Adverse Effect On Fertility

    Despite the rumours and false reports circulating in social media, there are no indications whatsoever that women can become infertile after receiving a vaccination. Nor has there been an increase in the number of miscarriages or complications following a COVID-19 infection and the associated production of antibodies.

    Vaccines Not Usually Advised In Pregnancy

    If a vaccine uses a live version of the virus, such as the MMR vaccine, you’ll usually be advised to wait until after your baby is born before you get vaccinated.

    This is because there’s a potential risk that live vaccines could cause your unborn baby to become infected. But there’s no evidence that any live vaccine causes birth defects.

    Sometimes, a live vaccine may be used during pregnancy if the risk of infection is greater than the risk of the vaccination. Your midwife, GP or pharmacist can give you more advice about vaccinations during pregnancy.

    Live vaccines include:

    • MMR
    • oral polio
    • oral typhoid

    Can The Vaccine Affect My Fetus During Pregnancy Or Reach My Baby Through Breastfeeding

    The mRNA vaccines work by presenting your body with a small set of genetic instructions for producing the SARS-CoV-2 spike protein. Your body generates the protein and allows your immune system to learn what the protein looks like so it can recognize the protein if you should ever encounter the actual SARS-CoV-2 virus and prepare an immune response to keep you from getting sick. mRNA is extremely short-lived and easily degraded this is why the vaccine must be stored at such cold temperatures and used quickly after preparation. Once the vaccine has been injected into your arm, your body either uses the instructions to make those spike proteins or it rapidly breaks down the small amount of mRNA thats remaining. It is therefore extremely unlikely that any of the mRNA would be able to get into breast milk or into the fetus through the placenta. Additionally, because its so easily degraded, it cannot survive the acidic environment of your babys stomach, so the vaccine itself cannot affect your baby.

    The vaccine is made up of mRNA, and contains no live virus. Therefore, it is impossible to contract COVID-19 from the vaccine, or spread the virus to others.

    Do I Need To Delay Getting Pregnant Or Fertility Treatments If Im Planning On Getting Vaccinated

    H1N1 flu vaccines safe during pregnancy

    Current recommendations say there is no reason to delay conception. If you become pregnant after receiving your first dose of the COVID-19 vaccine, you should not delay getting the second booster dose as scheduled. The only possible risk physicians are currently aware of with the vaccine is the possibility of a fever following the second dose, a side effect experienced by around 10-15% of vaccine recipients. In animal studies, high fevers in early pregnancy have been associated with a slight increase in risk of birth defects and pregnancy loss. If this is a concern, the current recommendation is that you take a pregnancy-safe fever reducer such as Tylenol if you experience a fever after getting vaccinated.

    If you are undergoing fertility treatments, the current recommendation is to continue the treatments and to get vaccinated. The American Society for Reproductive Medicine recommends vaccination in people planning to conceive spontaneously or with assisted reproductive technology, like IVF . A recent study showed no difference in IVF success outcomes in people who had been vaccinated against or previously infected with COVID-19. Speak with your physician and/or fertility specialists to make the decision that is best for you.

    Safety During Pregnancy And Breastfeeding

    Pregnancy increases the risk of severe illness from COVID-19. Getting this disease during pregnancy increases the risk for:

    • premature birth
    • caesarean delivery
    • stillbirth

    The National Advisory Committee on Immunization recommends you get a complete series with an mRNA COVID-19 vaccine if you’re pregnant or breastfeeding. Getting the COVID-19 vaccine can prevent serious illness, hospitalization and complications.

    Evidence about the safety and effectiveness of COVID-19 vaccination during pregnancy, has been growing from real-world use. The data shows that mRNA COVID-19 vaccines are safe for people who are pregnant or breastfeeding. No safety concerns were identified in a study of more than 35,000 pregnant people who received an mRNA COVID-19 vaccine within 30 days of conception.

    Pregnant people can get vaccinated against COVID-19 at any time during pregnancy or while breastfeeding.

    Immunization Of Household Contacts Of Pregnant Women

    Pregnancy in a household does not affect immunization indications for any other members of the household. Indeed, pregnancy should be used as an opportunity to update immunization of susceptible household contacts, including live vaccines such as rotavirus, MMR, MMRV, varicella, zoster and LAIV.

    In the unlikely event of a household contact being vaccinated against smallpox, extreme precautions should be taken to prevent transfer of the vaccinia virus to unvaccinated household and other close contacts, pregnant or not. Such precautions can include isolation of the vaccinee from pregnant household contacts until the vaccine scab falls off.

    Which Vaccines Do I Need After My Baby Is Born

    CDC report says COVID-19 vaccine safe during pregnancy

    After your baby is born, you may need to get vaccines to protect against:

    • Whooping cough: If you didnt get the whooping cough vaccine when you were pregnant, youll need to get vaccinated right after delivery. Other people who spend time with the baby may also need to get the whooping cough vaccine.
    • Measles, mumps, and rubella, and chickenpox: If youre not already protected from measles, mumps, rubella, or chickenpox, youll need to get vaccinated before you leave the hospital.

    All routinely recommended vaccines are safe for breastfeeding women.

    Why You Need The Vaccine If You Are Pregnant

    If you have COVID-19 disease in later pregnancy, both you and your unborn baby are at increased risk of serious disease needing hospital treatment, and intensive care support. UK data has shown that almost every pregnant woman with COVID-19 disease who needed hospital treatment or intensive care, had not been vaccinated. The overall risk from COVID-19 disease for you and your new baby is low but has increased since the first waves of COVID-19.

    COVID-19 vaccines in pregnancy give you high levels of protection against disease. There is reassuring information on the safety of COVID-19 vaccines given to pregnant women in the UK, as well as other countries.

    It is important that you are protected with all your vaccine doses to keep you and your baby safe. Dont wait until after you have given birth.

    Pregnant women with underlying clinical conditions are at higher risk of suffering serious complications from COVID-19.

    Vaccine Safety By Type

    Generally, all vaccines except live vaccines can be safely administered to pregnant women. Live vaccines, on the other hand, are administered very selectively when there is imminent and substantial risk of increased morbidity and mortality. Good examples are vaccines for attenuated oral polio and yellow fever.

    Immunization Of Breastfeeding Women

    In general, routinely recommended vaccines can be safely administered to breastfeeding women. There are limited data available regarding the effects of immunization of breastfeeding women on their infants however, there have been no reported adverse events related to administration of routine vaccines. There is no evidence that immunization during breastfeeding will adversely influence the maternal or infant immune response.

    Annual influenza vaccination is recommended during breastfeeding if not given during that pregnancy. Women who are breastfeeding should be vaccinated with Tdap, Td, hepatitis B, hepatitis A, HPV, pneumococcal, meningococcal, Hib, IPV, rabies, inactivated typhoid, MMR, varicella and cholera-traveler’s diarrhea vaccines if indicated.

    It is not known whether LZV virus is secreted in human milk. Given the age indication for HZ vaccines , breastfeeding women are unlikely to be among the target population.

    Japanese encephalitis vaccine has not been studied in breastfeeding. It is an inactivated vaccine and there is no theoretical reason to suspect increased risk of adverse effects in the mother or infants. Breastfeeding women who must travel to areas where the risk of JE infection is high should be immunized if the risk of disease outweighs the unknown risk of vaccination to the woman and her breastfeeding infant.

    What Is A Vaccination

    H1N1 flu vaccines safe during pregnancy

    A vaccination is a shot that contains a vaccine. A vaccine is a medicine that helps protect you from certain diseases. During pregnancy, vaccinations help protect both you and your baby. Make sure your vaccinations are current before you get pregnant. And talk to your health care provider about vaccinations that are safe to get during pregnancy.

    Our vaccination chart shows which routine vaccinations are recommended before and during pregnancy. Its based on the chart from the Centers for Disease Control and Prevention shows which vaccinations are recommended before, during and after pregnancy.

    Before you get any vaccination, tell your provider if you have any severe allergies or if youve ever had a severe allergic reaction to a vaccine. An allergy is a reaction to something you touch, eat or breathe in that makes you sneeze, itch, get a rash or have trouble breathing. For example, some vaccines are made with eggs. If youre allergic to eggs, those vaccines may cause an allergic reaction for you. If you have allergies, your provider can tell you which vaccines are safe for you. And you may need to get the vaccine at your providers office or at a hospital or health clinic so you can get treatment quickly if you have an allergic reaction.
