To get the yellow fever vaccine in the United States, you need to visit a certified yellow fever vaccination center. Unlike routine shots you can get at any pharmacy, this vaccine is only available at clinics specifically authorized by state health departments and registered with the CDC. The process is straightforward once you know where to look, but you’ll want to plan ahead since the vaccine isn’t valid for border entry until 10 days after you receive it.
Finding an Authorized Vaccination Center
The CDC maintains a public, web-based directory called the U.S. Yellow Fever Vaccination Center Registry. You can search it by location to find a certified clinic near you. These centers include travel medicine clinics, some local health departments, and certain hospital-affiliated practices. Not every doctor’s office or pharmacy carries the vaccine, so checking the registry first saves you time.
When you call to book, ask about appointment availability and whether you need a travel consultation beforehand. Many travel clinics bundle the vaccination with a broader pre-trip health review, which can be helpful if you’re heading to a region where other vaccines or malaria prevention are also recommended.
When You Need It
There are two separate reasons you might need this vaccine, and they don’t always overlap. The first is personal protection: the CDC recommends vaccination for anyone nine months or older traveling to parts of Africa and South America where yellow fever virus actively circulates. These are classified as “endemic” or “transitional” risk areas. For regions with only low potential for exposure, vaccination is generally not recommended unless you’ll be there for an extended stay or expect heavy mosquito exposure.
The second reason is legal entry. Many countries require proof of yellow fever vaccination as a condition of crossing their border. Some require it from all arriving travelers. Others only require it if you’re coming from, or even transiting through, a country where yellow fever is present. These entry requirements exist independently of whether the destination itself has yellow fever risk. A country in Asia with no yellow fever at all may still demand your proof of vaccination if your flight connected through a country in Africa’s yellow fever belt.
You’ll need to check both the CDC’s health recommendations and your destination country’s entry requirements before your trip, since they can differ.
The Yellow Card: Your Proof of Vaccination
When you get vaccinated at a certified center, you’ll receive an International Certificate of Vaccination or Prophylaxis, commonly called the “yellow card.” This is a small, folded paper document that serves as your official proof at international borders. Keep it with your passport.
The certificate becomes valid 10 days after vaccination. If you show up at a border crossing nine days after your shot, you can technically be turned away. Plan accordingly. Once those 10 days pass, your certificate is valid for life. The World Health Organization amended its rules to recognize lifetime protection from a single dose, so even if your yellow card has an expiration date printed on it, it remains legally accepted indefinitely.
Cost and Insurance
Yellow fever vaccination typically costs between $250 and $300, including any associated clinic or consultation fees. As a travel vaccine, it is generally not covered by standard health insurance plans or Medicare. Most clinics require payment at the time of service.
You can use a Health Savings Account (HSA) to pay, and some insurance providers will accept reimbursement claims after the fact, though there’s no guarantee. It’s worth checking with your insurer, but don’t count on coverage. Note that this cost is separate from any other travel vaccines you might need for the same trip.
How Far in Advance to Get Vaccinated
At minimum, you need the vaccine at least 10 days before arriving at any border that requires proof. In practice, aim for two to four weeks before departure. This gives the 10-day validity window comfortable clearance and accounts for the possibility that your nearest clinic might not have immediate appointments. During periods of vaccine supply constraints, availability can be limited, so booking early is especially important.
Who Should Not Get the Vaccine
Yellow fever vaccine is a live vaccine, which means it contains a weakened form of the virus. That makes it off-limits for certain groups. You cannot receive it if you:
- Are under 6 months old. The risk of a serious brain-related reaction in young infants is high, estimated at 50 to 400 cases per 100,000 infants vaccinated.
- Have a weakened immune system. This includes people with symptomatic HIV (or HIV with very low immune cell counts), organ transplant recipients, those on immunosuppressive medications, or anyone with certain thymus disorders.
- Have a severe egg allergy. The vaccine is produced using eggs and contains chicken proteins and gelatin. A history of serious allergic reaction to eggs, egg products, gelatin, or a prior dose of the vaccine is a firm contraindication.
Several other groups fall into a “proceed with caution” category rather than an outright ban. Adults over 60 face a higher rate of serious side effects: roughly 7.7 per 100,000 doses compared to 3.8 per 100,000 overall. Infants between 6 and 8 months, pregnant individuals, and those who are breastfeeding are also in this precaution zone. For these groups, the decision comes down to weighing the actual risk of yellow fever at the destination against the vaccine’s risks.
If You Can’t Be Vaccinated
If a medical condition prevents you from getting the shot, a physician at a certified yellow fever vaccination center can issue a medical waiver. This waiver is documented on your yellow card in lieu of a vaccination record. You’ll carry it the same way you’d carry proof of vaccination.
Here’s the important caveat: a medical waiver satisfies U.S. requirements, but the destination country has the final say. Border officials in some countries accept medical waivers without issue. Others may not, and they retain the right to quarantine, monitor, or deny entry to unvaccinated travelers regardless of the reason. If you’re traveling with a waiver, research how your specific destination handles exemptions before you go.
Vaccine Supply in the U.S.
The only yellow fever vaccine licensed for use in the United States is YF-VAX, manufactured by Sanofi Pasteur. Supply has been inconsistent in recent years, with production disruptions leading to periods of limited availability. During shortages, the FDA has allowed clinics to use Stamaril, a yellow fever vaccine manufactured in France and used in over 70 countries but not formally licensed in the U.S. Stamaril is distributed through an Expanded Access Program, and only participating clinical sites can administer it.
If your nearest clinic is out of stock, check other authorized centers in your region or contact your state health department for guidance. Supply constraints are another reason to schedule your vaccination well before your departure date rather than leaving it to the last week.
