Shingles Vaccine in Singapore
Shingles, also known as herpes zoster, can cause severe pain and complications that may affect quality of life, particularly in older adults. In Singapore, approximately one in three people may develop shingles in their lifetime. This patient guide explains shingles vaccination in Singapore, including who it may be suitable for, dosing, possible side effects, cost considerations, how it works, and what to expect during the vaccination process, with reference to information from MOH, HSA and HealthHub where relevant.

What is the Shingles Vaccine?
The shingles vaccine is a preventive immunisation designed to protect against herpes zoster, commonly known as shingles. This vaccine works by boosting your immune system’s ability to keep the varicella-zoster virus (VZV) – the same virus that causes chickenpox – dormant in your body. After recovering from chickenpox, the virus remains inactive in nerve tissues. Years or decades later, it can reactivate as shingles, causing a painful rash and potential complications.
In Singapore, the recombinant zoster vaccine (Shingrix) is the primary vaccine available for shingles prevention. This vaccine contains a non-live component of the virus combined with an adjuvant system that enhances immune response. Clinical studies show the vaccine provides strong protection against shingles and significantly reduces the risk of postherpetic neuralgia, a chronic pain condition that can persist after the shingles rash heals. The vaccine is administered as a two-dose series and has demonstrated effectiveness rates exceeding 90% in preventing shingles across various age groups.
Who Should Get the Shingles Vaccine
Ideal Candidates
Contraindications
- Current moderate to severe illness with fever
- Known severe allergic reaction to vaccine components
- Individuals with immune system concerns should consult a doctor to confirm whether the shingles vaccine is suitable
- Pregnant women (vaccination should be delayed)
- Current shingles outbreak (wait until fully recovered)
- Recent blood transfusion or immunoglobulin therapy (may need to delay)
The decision to receive the shingles vaccine should be made in consultation with a healthcare provider who can assess your individual health status and risk factors. Certain medical conditions may require special consideration or timing adjustments for vaccination.
Vaccine Types & Administration
-
Recombinant Zoster Vaccine (Shingrix)
The recombinant zoster vaccine is currently the preferred shingles vaccine in Singapore. This non-live vaccine contains glycoprotein E, a protein found on the varicella-zoster virus, combined with an adjuvant system (AS01B) that enhances the body’s immune response. The vaccine requires two doses administered 2 to 6 months apart for optimal protection.
-
Live Attenuated Vaccine (Zostavax)
While less commonly used now, the live attenuated vaccine was the first shingles vaccine available. It contains a weakened form of the varicella-zoster virus and requires only a single dose. Its effectiveness is lower than the recombinant vaccine, particularly in older adults.
-
Vaccine Storage & Handling
The shingles vaccine requires proper storage in refrigerated conditions between 2°C to 8°C. Healthcare facilities maintain strict cold chain protocols to ensure vaccine potency. The vaccine is prepared and administered by trained healthcare professionals following established safety protocols.

The Vaccination Process
Pre-Vaccination Assessment
Before receiving the shingles vaccine, you’ll undergo a brief health screening. The healthcare provider will review your medical history, current medications, and any allergies. They’ll also confirm you’re not currently ill with fever or acute infection. No special preparation such as fasting is required. Wear clothing that allows easy access to your upper arm where the injection will be administered.
During the Vaccination
The vaccination process is straightforward and typically takes less than 15 minutes. After cleaning the injection site with an antiseptic, the healthcare provider administers the vaccine into the deltoid muscle of your upper arm using a small needle. Most people experience only mild discomfort similar to other routine vaccinations. The vaccine is given as a 0.5ml injection, and you’ll receive documentation of your vaccination for your health records.
Immediate Post-Vaccination
After receiving the vaccine, you’ll be observed for 15-20 minutes to ensure no immediate adverse reactions occur. The healthcare provider will schedule your second dose appointment if receiving the two-dose series. You’ll receive information about potential side effects and when to seek medical attention. Most people can resume normal activities immediately after vaccination, though some prefer to rest if they experience mild side effects.
Shingles Vaccine Side Effects
- First 24-48 hours: Common shingles vaccine side effects may include pain, redness, or swelling at the injection site. Some people may also experience fatigue, headache, muscle aches, chills, or a low-grade fever.These reactions are usually part of the body’s immune response to the vaccine and often improve within a few days.
- How to Manage Side Effects: You may apply a cool compress to the injection site if there is soreness or swelling. Rest, drink enough fluids, and consider paracetamol for discomfort if it is suitable for you.
- When to Seek Medical Advice: Contact a healthcare provider if side effects persist beyond a week, become worse, or feel unusual. Seek urgent medical attention if you experience symptoms of a serious allergic reaction, such as breathing difficulty, facial swelling, or widespread rash.
- After Your Shingles Vaccine: If you are receiving a two-dose shingles vaccine, staying up to date with the second dose is important. Keep your vaccination records and inform healthcare providers about your shingles vaccination status during future medical consultations.

Benefits of Shingles Vaccination
The shingles vaccine offers substantial protection against a condition that affects approximately 1 in 3 people during their lifetime. Primary benefits include a significant reduction in shingles risk – studies show over 90% effectiveness in preventing shingles in adults aged 50 and older. Even if breakthrough shingles occurs in vaccinated individuals, the severity and duration are typically much reduced.
Beyond preventing the acute phase of shingles, vaccination dramatically reduces the risk of postherpetic neuralgia (PHN), a debilitating complication involving chronic nerve pain that can last months or years after the rash heals. The vaccine also helps prevent other shingles complications such as vision problems when the virus affects the eye, hearing issues, and rare but serious neurological complications. For many adults, the peace of mind knowing they’re protected against this painful condition represents a significant quality of life benefit.
Risks & Potential Complications
-
Common Side Effects
Most people experience only mild side effects from the shingles vaccine. These include injection site reactions such as pain (affecting up to 80% of recipients), redness, and swelling. Systemic side effects like fatigue, muscle pain, headache, shivering, fever, and gastrointestinal symptoms occur in about 40-60% of people. These effects typically last 1-3 days and can be managed with rest and over-the-counter pain relievers.
-
Rare Complications
Serious adverse events are extremely rare. Severe allergic reactions (anaphylaxis) occur in approximately 1 in 1 million doses. Other rare side effects may include gout flares in people with a history of gout. The recombinant vaccine cannot cause shingles itself as it doesn’t contain live virus.
Healthcare providers are trained to recognise and manage any adverse reactions. The vaccination setting is equipped with necessary medications and equipment to handle emergencies. The benefits of vaccination far outweigh the risks for eligible individuals, but discussing any concerns with your healthcare provider ensures informed decision-making.
Shingles Vaccine Cost in Singapore
The cost of the shingles vaccine in Singapore may vary depending on the clinic, vaccine availability, consultation fees, administration fees, and whether you are eligible for subsidies.
The shingles vaccine is usually given as a two-dose course. MOH states that eligible Singaporeans can expect to pay around $75 to $300 per course of Shingrix, while eligible Permanent Residents can expect to pay around $450 per course, depending on subsidy eligibility and care setting.
Patients are encouraged to contact the clinic directly to confirm current vaccine availability, estimated fees, and whether any subsidy or payment support may apply.
-
What Affects the Cost?
The final cost may depend on:
- The shingles vaccine used
- The number of doses required
- Doctor consultation fees
- Vaccine administration fees
- Subsidy eligibility
- Whether the patient is a Singapore Citizen, Permanent Resident, or foreigner
-
How Many Doses Are Needed?
The shingles vaccine is given as a two-dose course. HealthHub states that adults aged 60 and above should receive two doses, usually 2 to 6 months apart. For immunocompromised adults aged 18 to 59, the interval may be shortened to 1 to 2 months if earlier protection is required.
Completing both doses helps ensure the vaccination course is properly completed.
Walk-In vs Appointment
Walk-in availability may depend on clinic schedule and vaccine stock. It is recommended to call ahead before visiting to confirm shingles vaccine availability, expected cost, and the timing of the second dose.

Frequently Asked Questions (FAQ)
Who should get the shingles vaccine?
The shingles vaccine may be suitable for adults who have a higher risk of shingles or shingles-related complications. In Singapore, shingles vaccination is included under the National Adult Immunisation Schedule for adults aged 60 and above, and immunocompromised adults aged 18 to 59. Adults aged 50 and above may also speak with a doctor to check whether the shingles vaccine is suitable based on their health profile.
What are the side effects of the shingles vaccine?
Common side effects of the shingles vaccine may include pain, redness, or swelling at the injection site. Some people may also experience headache, muscle aches, fatigue, fever, or feel faint after vaccination. These side effects are usually short-term, but patients should seek medical advice if symptoms worsen or do not improve.
How much is the shingles vaccine in Singapore?
The cost of the shingles vaccine in Singapore may vary depending on the clinic, consultation fees, administration fees, vaccine availability, and subsidy eligibility. MOH states that eligible Singaporeans can expect to pay around $76 to $300 for a complete two-dose course of Shingrix after subsidies, while eligible Permanent Residents can expect to pay around $450. Patients should contact the clinic directly to confirm current fees and availability.
How many doses of the shingles vaccine do I need?
The shingles vaccine is given as a two-dose course. For adults aged 60 and above, the two doses are usually given 2 to 6 months apart. For immunocompromised adults aged 18 to 59, the interval may be shortened to 1 to 2 months if earlier protection is needed, based on medical advice.
If I’ve already had shingles, should I still get vaccinated?
Yes, vaccination is still recommended even if you’ve had shingles previously. While having shingles provides some natural immunity, it’s temporary and incomplete. Studies show that shingles can recur, with about 5-6% of people experiencing a second episode. The vaccine provides stronger and longer-lasting protection than natural infection. Wait until the shingles rash has completely healed before getting vaccinated.
How long does protection from the shingles vaccine last?
Current research shows the recombinant shingles vaccine maintains high effectiveness for at least 7 years after vaccination, with protection levels remaining above 85%.
Long-term studies are ongoing, but initial data suggests protection may last much longer. Unlike some vaccines that require annual boosters, the shingles vaccine provides durable immunity after completing the recommended series. Your doctor will advise if any additional doses are recommended in the future based on emerging evidence.
Can I receive the shingles vaccine with other vaccines?
Yes, the recombinant shingles vaccine can be administered at the same visit as other vaccines, including the influenza vaccine and pneumococcal vaccine. However, they should be given at different injection sites. Timing considerations may apply for certain vaccines. Live vaccines should be given either on the same day or separated by at least 4 weeks. Your healthcare provider will review your vaccination history and recommend appropriate scheduling.
What’s the difference between the chickenpox vaccine and shingles vaccine?
While both vaccines protect against diseases caused by the varicella-zoster virus, they serve different purposes. The chickenpox vaccine prevents the initial infection in children and adults who’ve never had chickenpox. The shingles vaccine boosts immunity in people who’ve already had chickenpox to prevent virus reactivation as shingles. The vaccines have different formulations and strengths designed for their specific preventive roles.
Are there any medications I should avoid before getting vaccinated?
Most medications don’t interfere with the shingles vaccine. Inform your healthcare provider about all medications you’re taking, particularly immunosuppressive drugs, chemotherapy, or high-dose steroids. These may affect vaccine timing or effectiveness. Antiviral medications like acyclovir should be stopped 24 hours before vaccination and avoided for 14 days after. Your doctor will provide specific guidance based on your medication regimen.
What should I do if I miss my second dose appointment?
If you miss your scheduled second dose, contact your healthcare provider to reschedule as soon as possible. The second dose can be given anytime between 2 to 6 months after the first dose. If more than 6 months have passed, you should still complete the series – there’s no need to restart. You’re not fully protected until you’ve received both doses, so completing the series promptly is important for optimal protection against shingles.
Conclusion
The shingles vaccine represents an important preventive health measure for adults in Singapore, offering robust protection against a potentially debilitating condition. With effectiveness rates exceeding 90% and a strong safety profile, vaccination provides peace of mind and helps maintain quality of life as we age. Whether you’re approaching 50 or already in your senior years, discussing shingles vaccination with a healthcare provider can help you make an informed decision about protecting your health.
