TRAVEL HEALTH
Travel Health in Pregnancy
How pregnancy changes the travel-health conversation, and when a pre-travel consultation is especially sensible.
Pregnancy changes the travel-health conversation in several important ways. Some vaccines are contraindicated during pregnancy. Some destinations carry risks — particularly malaria and Zika — that require a more cautious assessment. Airline policies may restrict travel beyond certain gestational ages. And the practical considerations — access to medical care abroad, travel insurance limitations, management of pregnancy-related symptoms while travelling — all need to be thought through before departure.
A pre-travel consultation through the travel clinic helps ensure that advice is proportionate to both the destination and the stage of pregnancy.

Vaccines to avoid during pregnancy
Live vaccines are generally contraindicated in pregnancy. This includes yellow fever, MMR, varicella (chickenpox), and BCG. The yellow fever restriction is particularly relevant for travel, since some countries require a valid yellow fever certificate for entry. If travel to a yellow fever zone is unavoidable during pregnancy, the risks and benefits need careful clinical discussion — in some circumstances a medical waiver letter may be issued instead. Inactivated vaccines — such as hepatitis A, hepatitis B, injectable typhoid, and inactivated polio — are generally considered safe in pregnancy when clinically indicated, but the decision should still be made by a GP with knowledge of the patient’s medical history and gestation.
Infection risk
Malaria and Zika risk during pregnancy
Malaria in pregnancy carries serious risks including miscarriage, premature delivery, low birth weight and maternal anaemia. Not all antimalarial medications are suitable during pregnancy. The safest approach is often to avoid high-risk malaria destinations during pregnancy where possible.
Zika virus — transmitted by mosquitoes — poses a risk of congenital abnormalities if contracted during pregnancy. There is no vaccine for Zika. Current advice is to avoid or defer travel to areas with active Zika transmission during pregnancy. Insect-bite prevention is the main protective measure.

Practical travel considerations during pregnancy
Most airlines allow travel up to 36 weeks for uncomplicated single pregnancies and 32 weeks for twins, though policies vary and some carriers require a fit-to-fly letter after 28 weeks. Long-haul flights increase DVT risk, which is already elevated in pregnancy — compression stockings, regular movement, and adequate hydration are important. Travel insurance may not cover pregnancy-related complications in all policies, so checking cover before booking is essential. Access to reliable obstetric care at the destination should also be considered, particularly for travel after 24 weeks.
Pre-travel review
When a pre-travel consultation is especially important
A consultation is particularly worthwhile for pregnant women travelling to malaria or Zika risk areas, for longer trips or remote destinations, for travel after 28 weeks, for patients with pregnancy complications or underlying medical conditions, and for any traveller who is unsure which vaccines are safe and which should be avoided. At Basuto, the travel clinic can coordinate with antenatal care to ensure advice is consistent with the overall pregnancy plan.
Common questions
Are travel vaccines safe in pregnancy?
It depends on the vaccine. Inactivated vaccines are often acceptable in pregnancy where the travel risk warrants it, while live vaccines are generally avoided unless the risk of disease clearly outweighs the theoretical vaccine risk. The GP reviews your destination and trimester before advising on each vaccine individually — a blanket “safe in pregnancy” statement is not clinically accurate.
How does pregnancy affect the decision on antimalarials?
Pregnancy changes the risk-benefit calculation significantly. Some antimalarials are not recommended in pregnancy, and for high-risk destinations the safer advice may be to reconsider or defer the trip. Pregnant patients travelling to malaria-risk areas should have this reviewed at the appointment well before departure.
Which destinations warrant extra caution during pregnancy?
Regions with active Zika transmission, malaria risk, altitude above 3,500m, limited medical facilities, or high infection burden (for example, certain gastrointestinal infections) warrant more careful review in pregnancy. The GP can help weigh whether the trip is advisable as planned, whether additional precautions reduce risk sufficiently, or whether rescheduling would be sensible.
