Zanzibar Vaccinations & Health: What You Actually Need to Know

Ask about vaccines for Zanzibar in any travel Facebook group and you'll get wildly different answers — some people say you need a fistful of shots, others say none of it matters for a beach holiday. Here's the actual picture, split clearly into what's required and what's recommended.

Do You Need Vaccinations for Zanzibar?

For most travellers, no vaccinations are required to enter Zanzibar. The one exception is yellow fever, and only in specific cases. Everything else on this page is recommended, not mandatory, and nothing beyond yellow fever is checked at the border.

Yellow Fever — Required Only in Specific Cases

Zanzibar doesn't require a yellow fever vaccination for travellers arriving directly from most countries, including the US, UK, Canada, Australia, and most of Europe.

It's only required if you're arriving from, or have transited more than 12 hours through, a country with yellow fever risk. If that applies to you, you'll need to carry your International Certificate of Vaccination (the "yellow card") and present it at immigration. Without it, you can be denied entry or vaccinated on the spot.

Risk countries are mostly in parts of Africa and South America — but the exact list changes periodically, so don't rely on a static list from any blog, including this one. Check the current WHO yellow fever country list before you travel, or ask your doctor or travel clinic directly.

We also mention this requirement briefly in our Zanzibar Visa & Entry Requirements guide — that post covers your visa and the mandatory ZIC travel insurance, worth reading alongside this one since you'll need both sorted before you land.

Malaria — Recommended for Everyone, Regardless of Where You Stay

This is the one most people underestimate. Zanzibar sits at sea level, and health authorities including the CDC, WHO, and UK NHS all recommend antimalarial tablets for anyone visiting, no matter which part of the island you're staying in or what kind of accommodation you've booked.

What malaria actually is

Malaria is a mosquito-borne illness, spread by the bite of an infected Anopheles mosquito. It's not contagious between people, and it's not something you catch from food, water, or swimming. The mosquitoes that carry it are most active from dusk to dawn, so risk is tied to evenings and nighttime, not daytime activities on the beach or in the water.

How to avoid it

Two things work together: prevention and prophylaxis.

Prevention means avoiding bites — insect repellent in the evenings, covering arms and legs after sunset, and sleeping under a net or with screens/air conditioning if your room doesn't already have them.

Prophylaxis means taking antimalarial tablets before, during, and after your trip, prescribed by a doctor or travel clinic. This is the part most people skip, and it's the part every major health authority recommends regardless of how careful you are with bite prevention.

Neither one replaces the other — bite prevention lowers your exposure, tablets protect you if prevention isn't perfect, which, realistically, it never fully is.

It's not required at the border — nobody will check — but it's the standard, consistent recommendation across every major health authority, not just a cautious extra.

Speak to a doctor or travel clinic about which antimalarial suits you, ideally a few weeks before you travel. Options include atovaquone-proguanil, doxycycline, and mefloquine, each with different dosing schedules.

Other Vaccines Worth Discussing With a Doctor

Not required for entry, but commonly recommended for travel to this region:

• Hepatitis A
• Typhoid
• Routine vaccines (make sure MMR, tetanus/diphtheria, and polio are up to date)

None of these are checked at the border. They're standard travel-health advice, not Zanzibar-specific requirements.

The Short Version

• Yellow fever: only if arriving from a risk country
• Malaria tablets: recommended for everyone, not checked at entry
• Everything else: a normal pre-travel doctor conversation, not something specific to Zanzibar

As always, this isn't medical advice — talk to a doctor or travel clinic about what's right for you, ideally a few weeks before you go.
