We administer the quadrivalent influenza vaccine, which protects against four strains of the virus in line with current WHO recommendations. This guide covers everything expats and Bangkok residents need to know — which vaccine we use, who should get it, what to expect at your appointment, and how our pricing compares to hospitals and other clinics across the city.
Influenza in Bangkok: Why Vaccination Matters for Expats
Influenza is a contagious respiratory virus that infects the nose, throat, and lungs. Unlike a common cold, the flu can cause severe illness, hospitalisation, and — in high-risk individuals — death. Thailand experiences year-round influenza activity, with peaks typically between June and August and again between December and February. Unlike temperate climates where flu season follows a predictable winter pattern, Bangkok’s tropical environment means the virus circulates throughout the year.
For expats in Bangkok, the annual flu shot is one of the most straightforward and cost-effective ways to protect your health. A single dose reduces the risk of contracting influenza by approximately 40 to 60% when the vaccine strains are well-matched to the circulating virus, according to the US Centers for Disease Control and Prevention (CDC, 2023). Beyond protecting yourself, vaccination reduces the chance of passing the disease on to more vulnerable people around you — older adults, young children, and those with underlying health conditions who face greater risk of serious complications.
Which Influenza Vaccine Is Available at HealthDeliver Bangkok?
HealthDeliver administers the quadrivalent (4-strain) influenza vaccine — the current standard of care recommended by the World Health Organization (WHO) and the Thai Ministry of Public Health. The quadrivalent formulation protects against four influenza virus strains simultaneously: two influenza A strains and two influenza B strains. This offers broader protection than older trivalent (3-strain) vaccines, which are now largely phased out in favour of the 4-strain formulation.
Vaccine strains are selected and updated annually by WHO’s Global Influenza Surveillance and Response System (GISRS) — a network of over 150 national influenza centres in more than 120 countries — to ensure maximum protection against the strains most likely to circulate in the coming season. This is why an annual flu shot is recommended rather than a one-time vaccination.
For patients with a known egg allergy: most influenza vaccines are produced using egg-based manufacturing processes and contain trace egg proteins. If you have a documented egg allergy, please inform our doctor before vaccination. Egg-free quadrivalent influenza vaccines are available and can be sourced on request — your doctor will advise on the most appropriate option for your situation.
Who Should Get a Flu Vaccine? Conditions and Risk Groups
Annual influenza vaccination is recommended for all adults in Thailand, regardless of underlying health status. Certain groups face a higher risk of serious illness and are particularly strongly advised to get vaccinated:
- Adults aged 65 and above — older age significantly increases the risk of severe influenza complications
- Pregnant women — influenza during pregnancy carries increased risk of hospitalisation and preterm birth
- Children aged 6 months to 18 years — particularly those under 5 who face elevated risk of serious disease
- Adults with chronic medical conditions including asthma, diabetes, heart disease, kidney disease, and immunocompromising conditions
- Healthcare workers and those in high-contact roles
- Frequent travellers — particularly those moving between countries or regions with different circulating strains
For expats in Bangkok, annual vaccination is advisable regardless of health status. Living in a tropical environment with year-round flu activity, combined with frequent international travel, creates sustained exposure risk. Getting vaccinated each year — ideally before the June-August peak season, or as soon as you remember if you have missed the window — is a sensible, low-effort way to protect yourself and avoid a preventable illness disrupting your work or travel.
Flu Vaccine Appointment at HealthDeliver: What to Expect
Getting your influenza vaccination at HealthDeliver is straightforward. Walk-in appointments are welcome at all three Bangkok clinics — no advance booking is required, though contacting us via LINE or WhatsApp ahead of your visit ensures you are seen promptly.
When you arrive, a brief medical consultation is conducted before vaccination. Your doctor will ask about any allergies — particularly to eggs — and any previous reactions to flu vaccines. This screening ensures the vaccine is clinically appropriate for you. The injection itself takes seconds. A short observation period of approximately 15 minutes is recommended following vaccination to monitor for any immediate reactions, which are rare.
You will receive a vaccination record documenting the vaccine brand, batch number, and date — useful for workplace, school, or travel documentation requirements. If you need a formal vaccination certificate, inform our team at the time of booking and we will ensure it is prepared.
Flu Shot Cost in Bangkok: Clinic vs Hospital Pricing
At HealthDeliver, a quadrivalent influenza vaccination costs ฿450 per dose — inclusive of the medical consultation. Here is how that compares across different types of providers in Bangkok:
- HealthDeliver Medical Clinic: ฿450 per dose, inclusive of consultation. Walk-in available, three central Bangkok locations.
- Other private clinics (PSK Clinic, MedConsult, WellMed): Typically ฿650 to ฿790 per dose depending on the clinic and vaccine brand used.
- Major international hospitals (Bangkok Hospital, Bumrungrad): Typically ฿990 to ฿1,050 per dose, reflecting the higher overhead of a large hospital setting. The vaccine itself is clinically equivalent.
- Public hospitals and community health centres: Subsidised flu vaccines are available for eligible Thai nationals through the government programme, primarily for high-risk groups including the elderly and pregnant women. Generally not accessible to expats without a Thai government health card.
The vaccine at a private clinic and at a major hospital is clinically the same — the difference is cost and convenience. For most expats seeking a straightforward annual flu shot, a private clinic like HealthDeliver offers the best combination of accessibility, English-language care, and value.
Where to Get a Flu Shot in Bangkok — Opening Hours and Booking
HealthDeliver’s three Bangkok clinics are all open daily and easily accessible by BTS Skytrain and MRT. Walk-ins are welcome at all locations, and same-day appointments are available.
- HealthDeliver Asok: Prasanmit Plaza, Sukhumvit Soi 23 — a short walk from BTS Asok and MRT Sukhumvit.
- HealthDeliver Sathorn: Central Sathorn district, accessible from BTS Chong Nonsi. Serving Sathorn, Silom, and Bang Rak.
- HealthDeliver Phrom Phong: Near BTS Phrom Phong. Serving Phrom Phong, Thonglor, and Ekkamai.
The 3/2/1 Rule for Vaccines: Timing Your Flu Shot Around Travel
If you are planning travel and wondering when to get your flu shot — here is the simple guideline most travel doctors use. The 3/2/1 rule refers to vaccines that should ideally be given 3 months, 2 months, or 1 month before departure to allow sufficient time for immunity to develop before exposure.
For the influenza vaccine specifically, immunity typically develops within two weeks of vaccination. So if you are travelling during or heading into flu season, aim to get vaccinated at least two weeks before your departure date. There is no waiting period required between the flu vaccine and most other common travel vaccines — it can be given alongside Hepatitis A, Hepatitis B, typhoid, and others on the same visit where clinically appropriate.
Your HealthDeliver doctor will advise on the optimal timing and combination if you are planning travel vaccinations alongside your annual flu shot.

Is it worth getting vaccinated against influenza in Thailand?
Yes. Thailand experiences year-round influenza activity with two seasonal peaks, and the annual flu shot is recommended for all adults. For expats, frequent travel between countries, exposure to diverse virus strains, and the disruption a flu illness causes to work and daily life make annual vaccination a sensible and cost-effective precaution. At ฿450 per dose at HealthDeliver, it is one of the lowest-cost health protections available.
What vaccines are recommended for Thailand?
Standard vaccinations recommended for Thailand include Hepatitis A, Hepatitis B, typhoid, influenza, and rabies for those with significant outdoor or animal exposure. Routine vaccinations including measles-mumps-rubella (MMR) and tetanus should also be up to date. Yellow fever vaccination is required if arriving from a yellow fever-endemic country. A travel health consultation at HealthDeliver provides a personalised recommendation based on your health history and travel plans.
Do I need an appointment to get a flu shot at HealthDeliver?
No. Walk-in flu vaccinations are available at all three HealthDeliver Bangkok clinics — Asok, Sathorn, and Phrom Phong. Booking ahead via LINE, WhatsApp, or the website is recommended during busy periods but not required. Most walk-in patients are seen within minutes of arrival.
What are common side effects of the influenza vaccine?
Common side effects are mild and short-lived — soreness, redness, or mild swelling at the injection site, low-grade fever, and fatigue for 24 to 48 hours. These are a normal immune response and not a sign that the vaccine has caused illness. Serious allergic reactions are rare. A 15-minute observation period following vaccination is standard. Contact our clinic if you experience any concerning symptoms after your jab.
Can I get a flu vaccine if I have an egg allergy?
Possibly — but tell your doctor before vaccination. Most standard influenza vaccines contain trace egg proteins. For patients with a documented egg allergy, egg-free quadrivalent options are available and can be sourced on request. Your HealthDeliver doctor will assess your allergy history and advise on the safest approach before proceeding.
