Vaccinations to Check Before Pregnancy: A Preconception Guide
Vaccinations to Check Before Pregnancy: A Preconception Guide
Planning a pregnancy is an ideal time to review your vaccination history. Some infections that are mild in adults can cause serious complications during pregnancy or affect the developing baby. Updating vaccines before conception is particularly important because some live vaccines are not recommended during pregnancy. (CDC)
Why Check Vaccinations Before Pregnancy?
Preconception vaccination can:
- Protect the mother from vaccine-preventable infections.
- Reduce the risk of infections affecting the fetus.
- Prevent congenital infections and birth defects, particularly from rubella.
- Provide antibodies that can help protect the newborn during the first months of life.
- Allow administration of vaccines that cannot normally be given during pregnancy. (CDC)
Important Vaccines to Review
| Vaccine | Before pregnancy | During pregnancy | Key point |
|---|---|---|---|
| MMR | Yes, if non-immune | ❌ Avoid | Live vaccine; complete before conception |
| Varicella | Yes, if non-immune | ❌ Avoid | Live vaccine; complete before conception |
| Influenza | Yes | ✅ Yes | Inactivated/recombinant vaccine preferred |
| Tdap | May be given if indicated | ✅ Yes | Recommended during every pregnancy, usually 27–36 weeks |
| COVID-19 | Keep up to date | Generally recommended according to current guidance | Discuss current formulation/timing |
| Hepatitis B | Check status and vaccinate if indicated | ✅ Can be given if indicated | Particularly important if susceptible/risk factors |
| Hepatitis A | If indicated | May be given when indicated | Consider risk factors |
| HPV | Can be completed before pregnancy | ❌ Not recommended during pregnancy | Resume after pregnancy if series incomplete |
| Meningococcal | If indicated | May be used when indicated | Risk-based |
| Travel vaccines | Review before travel | Depends on vaccine | Specialist advice may be needed |
Recommendations vary according to age, previous vaccination, immunity, occupation, medical conditions, travel and local epidemiology. (CDC)
1. MMR Vaccine — Especially Important
MMR protects against measles, mumps and rubella.
Rubella infection during pregnancy can cause congenital rubella syndrome, which may include hearing impairment, cataracts, congenital heart disease and neurodevelopmental problems. (CDC)
If immunity is uncertain, the clinician may review the vaccination record and, where appropriate, assess rubella immunity.
Important:
MMR is a live attenuated vaccine and should not be administered during pregnancy. CDC recommends avoiding pregnancy for 28 days after MMR vaccination. (CDC)
Exam point:
Rubella non-immune → MMR before pregnancy → avoid conception for at least 28 days.
2. Varicella Vaccine
Chickenpox during pregnancy can cause significant maternal illness and can occasionally affect the fetus/newborn.
Women without evidence of immunity should discuss varicella vaccination before pregnancy.
Varicella vaccine is a live vaccine and is contraindicated during pregnancy. CDC recommends avoiding pregnancy for 1 month after each dose. (CDC)
If two doses are required, the vaccination schedule should be completed before attempting conception.
3. Influenza Vaccine
Influenza can cause more severe illness during pregnancy.
The inactivated or recombinant influenza vaccine can be administered during pregnancy and is recommended seasonally. The live attenuated nasal influenza vaccine should not be used during pregnancy. (CDC)
Therefore, women planning pregnancy should ensure that their seasonal influenza vaccination is appropriate for the current season.
4. Tdap — Tetanus, Diphtheria and Pertussis
Tdap is particularly important because vaccination during pregnancy helps transfer maternal antibodies to the fetus, providing early protection against pertussis (whooping cough).
CDC recommends Tdap during every pregnancy, preferably at 27–36 weeks, even if the woman received Tdap during a previous pregnancy. (CDC)
So Tdap does not necessarily need to be given before conception simply because pregnancy is planned.
5. Hepatitis B Vaccine
Hepatitis B status should be reviewed during preconception and prenatal care.
Vaccination is particularly important for women who are susceptible or have risk factors for hepatitis B infection. Hepatitis B vaccination can also be administered during pregnancy when indicated. (CDC)
Testing for hepatitis B infection is also an important component of pregnancy care.
6. COVID-19 Vaccination
COVID-19 vaccination recommendations can change as vaccine formulations and public-health guidance evolve. Women planning pregnancy should discuss whether they are up to date with the currently recommended COVID-19 vaccine. (CDC)
Pregnancy itself is associated with a higher risk of severe COVID-19 illness, making vaccination an important part of maternal preventive care.
7. HPV Vaccine
HPV vaccination is recommended for eligible individuals who have not completed vaccination, but HPV vaccination is not recommended during pregnancy.
If pregnancy occurs after starting an HPV vaccine series, the remaining doses should generally be postponed until after pregnancy. An inadvertent dose during pregnancy is not considered an indication for pregnancy termination. (CDC)
Vaccines That Need Special Attention Before Pregnancy
The most important vaccines to identify before conception are the live vaccines:
🔴 MMR
Measles–Mumps–Rubella
🔴 Varicella
Chickenpox vaccine
These should generally be administered before pregnancy when indicated, because they are contraindicated during pregnancy. (CDC)
Simple Preconception Vaccination Checklist
Before trying to conceive, discuss the following with your healthcare provider:
☐ Review childhood and adult vaccination records
☐ Check whether MMR/rubella immunity is adequate
☐ Check varicella immunity
☐ Update MMR if indicated before pregnancy
☐ Update varicella vaccination if indicated before pregnancy
☐ Review seasonal influenza vaccination
☐ Review COVID-19 vaccination status
☐ Check hepatitis B vaccination/status
☐ Consider hepatitis A vaccination if risk factors are present
☐ Review HPV vaccination if eligible
☐ Review travel-related vaccines if international travel is planned
☐ Plan Tdap vaccination for 27–36 weeks of pregnancy
CDC specifically recommends maintaining an accurate vaccination record and reviewing it with the preconception healthcare professional. (CDC)
How Far Before Pregnancy Should Vaccination Be Completed?
For live vaccines, timing is particularly important.
- MMR: avoid pregnancy for at least 28 days after vaccination.
- Varicella: avoid pregnancy for 1 month after each dose.
- Inactivated vaccines such as influenza do not require this live-vaccine waiting interval. (CDC)
If a woman accidentally receives MMR or varicella vaccine shortly before discovering that she is pregnant, this is not by itself an indication to terminate the pregnancy; she should contact her healthcare provider for individualized counseling. (CDC)
Bottom Line
The key pre-pregnancy vaccination check is to identify immunity gaps—especially rubella and varicella—and correct them before conception. MMR and varicella vaccines are live vaccines and should not be given during pregnancy. In contrast, influenza and Tdap have important roles during pregnancy, with Tdap routinely recommended during each pregnancy at 27–36 weeks. (CDC)

Vaccinations to Check Before Pregnancy: 20 Important Points
Planning a pregnancy is an important opportunity to review your vaccination history. Some infections can cause serious complications during pregnancy, while certain vaccines are best completed before conception. A preconception consultation can help identify immunity gaps and create an appropriate vaccination plan.
For more pregnancy and women’s-health information, explore Wiki Health News and Femelife.
1. Check Your MMR Vaccination Status
Before pregnancy, check whether you are adequately protected against measles, mumps and rubella (MMR). Rubella infection during pregnancy can cause miscarriage and serious congenital abnormalities.
Read more about pregnancy planning and women’s health on Wiki Health News.
2. Confirm Rubella Immunity
Rubella immunity is particularly important before conception. If you are not immune, your doctor may recommend MMR vaccination before pregnancy.
Women planning pregnancy can also discuss preconception health and fertility planning with the specialists at Femelife.
3. Remember That MMR Is a Live Vaccine
MMR is a live attenuated vaccine and should not routinely be administered during pregnancy. When indicated, it should be given before conception. CDC guidance recommends avoiding pregnancy for at least 28 days after MMR vaccination.
4. Check Varicella Immunity
Varicella, or chickenpox, can cause significant maternal illness during pregnancy and may occasionally affect the fetus or newborn.
Check your vaccination records or discuss your immunity status with your healthcare professional before trying to conceive.
5. Complete Varicella Vaccination Before Pregnancy
Women without evidence of immunity may need varicella vaccination before pregnancy. Because varicella vaccine is a live vaccine, it should not be given during pregnancy.
For additional articles about healthy pregnancy preparation, visit Femelife Pregnancy & Women’s Health.
6. Allow Appropriate Time After Varicella Vaccine
If varicella vaccination is required, pregnancy should generally be avoided for one month after each dose, according to CDC guidance.
Your doctor can advise on the appropriate vaccination schedule based on your individual circumstances.
7. Review Influenza Vaccination
Influenza can cause more severe illness during pregnancy. Seasonal influenza vaccination is an important component of maternal preventive care.
For evidence-based health information covering infectious diseases and preventive healthcare, visit Wiki Health News.
8. Check Tdap Requirements
Tdap protects against tetanus, diphtheria and pertussis. Tdap is routinely recommended during every pregnancy, preferably between 27 and 36 weeks, to help protect the newborn against pertussis.
9. Review COVID-19 Vaccination
Women planning pregnancy should discuss whether their COVID-19 vaccination is up to date according to current recommendations.
Pregnancy planning should include vaccination review along with nutrition, folic acid, medications and other preventive-care measures.
10. Check Hepatitis B Protection
Hepatitis B vaccination status should be reviewed before pregnancy. Women who are susceptible or have relevant risk factors may benefit from vaccination.
Hepatitis B screening and appropriate preventive care are also important components of pregnancy care.
11. Discuss Hepatitis A Vaccination
Hepatitis A vaccination is generally considered according to individual risk factors. Your healthcare professional can determine whether vaccination is appropriate before or during pregnancy.
12. Review HPV Vaccination
Eligible women who have not completed HPV vaccination can discuss completing the vaccine series before pregnancy.
HPV vaccination is not recommended during pregnancy. If pregnancy occurs after the series has started, the remaining doses can generally be postponed until after pregnancy.
13. Review Meningococcal Vaccination When Indicated
Meningococcal vaccination is not routinely required for every woman planning pregnancy. It may be recommended in specific situations, including certain medical, occupational, travel or outbreak-related risks.
14. Consider Pneumococcal Vaccination for High-Risk Women
Women with certain medical conditions may require pneumococcal vaccination. The decision should be individualized according to the underlying condition and current vaccination recommendations.
15. Review Travel Vaccinations Before Conception
If you are planning international travel, discuss vaccinations before conception whenever possible.
Travel-related health planning can be particularly important for women undergoing fertility treatment or preparing for pregnancy. Femelife provides information related to fertility and reproductive health.
16. Keep an Accurate Vaccination Record
Keep a record of childhood and adult vaccinations. Bring your vaccination history to your preconception appointment.
If records are unavailable, your healthcare professional can determine whether vaccination or immunity testing is appropriate.
17. Discuss Occupational Exposure
Healthcare workers and people with occupational exposure to infectious diseases may require additional vaccination assessment.
A preconception visit provides an opportunity to review occupational risks and determine whether additional vaccines are required.
18. Review Vaccination After a Previous Pregnancy
If certain vaccines were missed during a previous pregnancy, discuss whether they should be administered before the next pregnancy or during the postpartum period.
19. Don’t Delay Preconception Counseling
Preconception counseling provides an opportunity to review vaccination status along with:
- Folic acid supplementation
- Medications
- Medical conditions
- Lifestyle factors
- Previous pregnancies
- Genetic risks
- Infection prevention
- Fertility considerations
