Iran Health & Vaccinations

By the Heritage Persia guiding team, Shiraz·Published 12 September 2026·Last reviewed 12 September 2026·The risk order, the vaccine list, and the thing that changed this year

Most health advice for Iran leads with vaccinations, which is roughly the least important thing on this page. The realistic risk order for a visitor is road traffic first, air quality second, heat third, and infectious disease a long way down — and the one item that has genuinely changed in 2026 is not a disease at all but the supply of medicine.

What follows is the vaccine list from the source that sets it, then the part we would actually spend your attention on: what you can no longer assume you will be able to buy once you are there.

The Vaccine List

Iran requires no vaccination certificate for entry from Europe or North America. A yellow fever certificate is required only if you are arriving from a country with a risk of transmission, which is the sole entry condition of this kind. Everything below is a recommendation rather than a rule, and the grouping follows the UK National Travel Health Network and Centre.

Malaria is not a consideration on the classic route. Low risk exists from March to November in rural south-eastern provinces and parts of the northern border; the corridor from Tehran to Shiraz has none, and no antimalarials are normally advised for a standard itinerary.

The Part That Changed in 2026

For years the honest advice was that Iranian pharmacies were cheap, everywhere, and better stocked than visitors expected, with most medicines sold without the prescription they would need at home. That is no longer a safe assumption, and we have corrected it elsewhere on this blog rather than leave it standing.

As of September 2026 Iran is short of roughly eight hundred pharmaceutical products, ninety of them classed as essential or life-saving, according to Hadi Ahmadi of the Iranian Pharmacists Association. Four hundred of the scarce items are ones Iran manufactures itself. The categories affected include cancer drugs, epilepsy and nerve-pain medication, antibiotics, insulin, antidepressants, and rotavirus and influenza vaccines.

Prices have moved with the shortage. Year on year, gabapentin is reported up 220 per cent, paracetamol 375 per cent, amoxicillin 285 per cent, fluoxetine 100 per cent and insulin by as much as 600 per cent.

The causes are stacked rather than singular: around forty-four pharmaceutical and medical-equipment companies damaged or destroyed since February 2026, a naval blockade restricting shipping through the Strait of Hormuz along with air, rail and overland routes, continued dependence on imported active ingredients, and the withdrawal of subsidised foreign currency for medical imports.

Bringing Your Own Medicines

Bring more than the trip requires — a week's surplus is the usual rule and we would double it here — and split it between your hand luggage and your case so that a delayed bag is an inconvenience rather than an emergency.

Keep everything in original packaging with the pharmacy label, and carry a copy of the prescription, ideally in English and naming the generic drug rather than only the brand. Brand names differ between countries and a generic name is what an Iranian pharmacist or doctor will recognise.

Some categories need more care. Medicines containing codeine, strong painkillers, sedatives and stimulants are controlled and may require documentation at the border; bring the prescription and only the quantity the trip needs. Any medicine that is contentious at home is likely to be contentious here, and the sensible step is to check your specific drug with the Iranian consulate before you fly rather than discover the answer at the airport.

If you use insulin or anything else that needs refrigeration, plan for it explicitly. Courtyard hotels do not always have room fridges, summer road transfers are long and hot, and insulin is among the medicines currently in shortest supply locally, so a cool bag and your own stock are not optional.

The Honest Risk Order

This is the table we would actually hand a traveller. It is ordered by how likely each item is to affect your trip, not by how alarming it sounds.

Notice that the two largest items are environmental rather than infectious, and that both are addressed by when and how you travel rather than by anything a clinic can give you.

Winter Air in the Cities

Iran's air pollution is not a footnote. Government-linked figures attribute nearly fifty-nine thousand deaths in the Iranian year to March 2025 to air pollution — around a hundred and sixty a day — with economic damage put at $17.2 billion. Ten major cities, including Tehran, Isfahan, Mashhad, Tabriz, Ahvaz and Yazd, exceeded WHO limits for fine particulates on hundreds of days, some districts at four to nine times the safe threshold.

For a visitor this matters mainly in winter and mainly in Tehran, where cold air sits trapped under the Alborz and the index climbs through November, December and January. Schools and offices close in the worst episodes, which is the signal to change your own plans rather than push through.

The practical response is modest: if you are travelling between November and February, weight your city days towards the morning, keep a reliever inhaler with you if you have asthma, and treat a heavily polluted day as a reason to take an indoor museum rather than a walking route. Isfahan and Shiraz are consistently better than Tehran, and Yazd and the desert are better again.

Food and Water

Tap water is treated and safe to drink in every city on the standard route, and Iranians drink it. In villages and in the far south we would use bottled or filtered water, which is what local practice does too.

Food-borne illness is uncommon and usually mild. Salads and herbs are washed as a matter of course in restaurants and the fresh herb plate served with almost every meal is not a risk worth avoiding. Street food is generally safe; the usual rule of eating where there is turnover applies here as anywhere.

Two genuine cautions. Unpasteurised dairy in rural areas carries a brucellosis risk and is worth declining. And raw camel products are best avoided on account of MERS, which has been reported in the region — this affects almost no ordinary itinerary but is the reason the advice exists. The food guide covers what to eat rather than what to avoid, which is the more useful half.

What Care Is Actually Like

Uneven, and better than most travellers expect where it is good. Global Affairs Canada puts it accurately: good health care is limited in availability and quality varies greatly across the country. Tehran, Isfahan, Shiraz and Mashhad have private hospitals with foreign-trained specialists and equipment that would not look out of place in southern Europe; provincial towns are a different proposition and rural areas more so again.

Two things about paying. More than seventy per cent of healthcare costs in Iran are met directly by patients rather than by insurance, so the cash-at-the-counter model you will encounter is the normal domestic one rather than something applied to foreigners. And because sanctions make it difficult for a Western insurer to transfer funds to an Iranian hospital, you pay in cash and claim afterwards — which our insurance guide sets out in full, including why your cash reserve is the real cover below the evacuation threshold.

Plan the route with the medical map in mind if you have a condition that could need attention. The classic corridor keeps you within about an hour of a major hospital throughout; the Lut, the Khuzestan plain and the mountain routes do not.

What We Would Actually Do

See a travel clinic six to eight weeks out. Hepatitis A and a tetanus check are the whole conversation for most people, and both are quick.

Build the medical kit first, not last. In 2026 it is the single most consequential thing in the suitcase, and the packing list has the contents.

Carry a one-page medical summary with your conditions, allergies, generic drug names and doses, and an emergency contact — in English, on paper, in your bag rather than only in your phone.

Choose the month with health in mind, because the two biggest risks on this page are seasonal. The month-by-month guide is the place to start.

And read the insurance page before you book, not after. When your government advises against all travel, the ordinary policy that would have paid for a medical evacuation does not.
