Yes, some travel vaccines are safe during pregnancy, but several must be avoided. Whether a vaccine is suitable depends largely on whether it is inactivated or live-attenuated. The specific destination, trimester, and your individual risk level all factor into the final decision. 

Read on to understand exactly which travel vaccines are off the table, which are generally fine, and when exceptions apply.

The Core Rule: Inactivated vs Live-Attenuated Vaccines

The single most important distinction in pregnancy vaccination is the type of vaccine involved. Inactivated vaccines contain killed viruses or bacteria. They cannot replicate in the body and pose no theoretical risk of infecting the foetus.

Live-attenuated vaccines are different. They contain weakened but still-living viral strains. There is a small theoretical risk the vaccine virus could cross the placenta, which is why most are avoided during pregnancy unless absolutely necessary.

As a general rule, health authorities advise pregnant women to avoid travelling to areas with active outbreaks or mandatory vaccination requirements where possible. Prevention is always simpler than managing exceptions.

Inactivated Travel Vaccines (Generally Considered Safe)

These vaccines have been used during pregnancy and are not contraindicated, particularly when the risk of exposure to the disease is real.

Hepatitis A and Hepatitis B

Both are inactivated vaccines. Hepatitis A is relevant for travel to many parts of Africa, Asia, and South America. Hepatitis B is recommended for destinations with high prevalence or where medical care may involve unscreened blood products.

Typhoid (Injectable Vi Vaccine Only)

The injectable typhoid vaccine is inactivated and considered appropriate in pregnancy when travel to endemic regions is unavoidable. The oral form is a different matter entirely — see the section below.

Tetanus, Diphtheria, and Polio

These are inactivated and often given as combined vaccines. Tetanus protection is particularly relevant for travel to areas with limited medical access, and the Td/IPV combination is routinely used in UK antenatal settings.

Rabies

The rabies vaccine is inactivated and can be given in pregnancy if there is a genuine risk of exposure, such as travelling to rural areas in South or Southeast Asia where post-bite treatment may not be readily available.

Japanese Encephalitis

Used for longer stays in rural parts of Asia, particularly during monsoon season. The inactivated version (Ixiaro) is not licensed in pregnancy but can be offered when the risk of contracting the disease is judged higher than the theoretical vaccine risk.

Meningitis ACWY

The quadrivalent meningococcal vaccine is inactivated and is routinely recommended for travel to sub-Saharan Africa or Saudi Arabia during Hajj and Umrah. It is considered safe in pregnancy.

Live Travel Vaccines (Usually Contraindicated)

These vaccines should not be given during pregnancy as a standard rule. There are very limited exceptions, discussed in the next section.

Yellow Fever

This is the most clinically significant contraindication for pregnant travellers. Yellow fever vaccine is a live-attenuated vaccine associated with a small risk of vaccine-associated neurological disease in infants. It is avoided in pregnancy, and alternatives or waivers should be discussed with a travel clinician.

Typhoid (Oral Capsules)

The capsule form of the typhoid vaccine is live-attenuated. Even though it targets the gut, it is still contraindicated during pregnancy. The injectable Vi polysaccharide vaccine is the correct alternative.

MMR (Measles, Mumps, Rubella)

MMR is a routine UK vaccine, but it is live. Pregnant women who are not immune to rubella should not receive MMR during pregnancy. It is given after delivery. For international travel, this becomes relevant in countries where measles outbreaks are ongoing.

BCG (Tuberculosis)

BCG is a live vaccine and is avoided during pregnancy. Most adults travelling to high-TB-burden countries for short trips would not routinely be given BCG anyway, but it should not be administered if pregnancy is confirmed.

Chickenpox (Varicella)

Varicella is live and contraindicated. Chickenpox in pregnancy can cause serious complications, including foetal varicella syndrome in the first and early second trimester. Women without immunity should be counselled carefully about travel risks.

The Risk vs. Benefit Exception for Mandatory Travel

Not every situation is straightforward. Sometimes travel cannot be delayed or altered, and a live vaccine becomes the lesser of two risks.

High-Risk Travel

If a pregnant woman must travel to a Yellow Fever endemic country and the disease risk at the destination is substantial, a travel clinician can make a case-by-case decision to administer the vaccine. This typically applies to travel to parts of sub-Saharan Africa and tropical South America.

The actual disease is often more dangerous than the vaccine itself. Yellow fever can cause multi-organ failure, and pregnancy increases vulnerability to severe illness. The risk-benefit discussion should happen with a specialist, ideally a GP with travel medicine experience or a dedicated travel clinic.

Medical Exemption Waivers

If a destination requires a valid Yellow Fever vaccination certificate (known as an ICVP) but the vaccine is contraindicated, a registered travel clinician can issue an official medical exemption waiver. This is a formal document and not a guarantee of entry, some countries still refuse entry without the certificate, regardless of the waiver.

Malaria Considerations During Pregnancy

Malaria is not vaccine-preventable in the standard sense, but it deserves specific mention here. Pregnant women are at substantially higher risk of severe malaria, miscarriage, preterm birth, and maternal death than the general population.

If travel to a malaria-endemic area is unavoidable, strict mosquito avoidance measures are non-negotiable. This means long-sleeved clothing, DEET-based repellent, insecticide-treated nets, and avoiding outdoor exposure at dawn and dusk.

Regarding antimalarials, choices are limited in pregnancy. Chloroquine and proguanil (Paludrine/Avloclor) can be used. Mefloquine (Lariam) is used in the second and third trimester in some cases. 

Doxycycline and atovaquone-proguanil (Malarone) are contraindicated. Always discuss antimalarial options with a pharmacist or clinician before travel.

Routine Pregnancy Vaccines to Confirm Before Travel

Before focusing on travel-specific vaccines, it is worth ensuring that standard antenatal vaccinations are up to date. These are recommended regardless of travel but are particularly relevant when heading abroad.

Flu (Inactivated Influenza)

The inactivated flu vaccine is recommended throughout pregnancy at any stage. Influenza in pregnancy carries a higher risk of hospitalisation, and the vaccine is offered free on the NHS. If travelling during flu season in the destination country, this is especially worth prioritising.

Tdap (Whooping Cough)

The pertussis-containing vaccine (Boostrix IPV in the UK) is routinely offered between 16 and 32 weeks, with the best protection for the baby conferred between 20 and 32 weeks. Pertussis outbreaks still occur internationally, and ensuring this is done before travel provides passive protection to the newborn.

RSV (Respiratory Syncytial Virus)

RSV vaccine (Abrysvo) has been offered to pregnant women in the UK from around 28 weeks since 2024. It passes antibodies to the baby before birth and reduces the risk of severe RSV bronchiolitis in the first six months of life. If travelling abroad and this has not yet been given, ask your GP or midwife before departure.

Frequently Asked Questions

Can I travel abroad in the first trimester without any vaccines?

If your destination does not require live vaccines and carries no significant disease risk, short-haul travel in the first trimester can be safe. Always get advice from your GP or midwife before booking.

Is there a specific month in pregnancy when vaccines are safest to receive?

Inactivated vaccines can be given at any stage. Some, like the whooping cough vaccine, have an optimal window between 20 and 32 weeks. Live vaccines are avoided throughout all three trimesters.

Will travel vaccines affect my baby’s own vaccination schedule after birth?

Inactivated vaccines given to the mother during pregnancy do not interfere with the baby’s own immunisation programme. Maternal antibodies passed to the baby are protective, not a barrier to later vaccinations.

What should I do if I have already received a live vaccine before realising I was pregnant?

Do not panic. The theoretical risk exists, but the actual incidence of harm is very low. Inform your midwife immediately and ask for a referral to the relevant specialist team for monitoring.

Are there any vaccines I should avoid even if they are listed as inactivated?

Japanese Encephalitis vaccine (Ixiaro) is inactivated but not licensed for use in pregnancy, meaning the manufacturer has not conducted trials in pregnant women. It may still be used on a risk-benefit basis. Always get this discussion in writing from your clinician.

Next Steps: Consulting a Travel Clinic

Pregnancy adds a layer of complexity to travel health that a standard GP appointment does not always have time to address properly. A dedicated travel clinic will assess the specific diseases circulating at your destination, the stage of your pregnancy, your vaccination history, and any underlying health conditions.

Book at least 6 to 8 weeks before your departure date. Some vaccines require multiple doses, and the timing matters. If you are travelling at short notice, contact a travel clinic as soon as possible to understand what can still be done safely.

Ask specifically about written documentation of any exemptions or clinical decisions made, particularly around Yellow Fever. This protects you at border control and ensures continuity of care when you return.
