Influenza Vaccine in Malaysia

Influenza is not “just a bad cold”. It can keep you in bed for a week, and older adults and people with diabetes, heart or lung disease are at real risk of complications such as pneumonia that end in hospital. The influenza vaccine (flu vaccine or flu shot) is the most effective way to protect yourself and the people around you. This guide covers who should get it, when, which vaccines are available in Malaysia, and what side effects to expect.

Is it flu or a cold?

	Influenza	Common cold
How it starts	Suddenly, often within hours	Gradually
Fever	Common, often high (38°C and above)	Uncommon or mild
Body aches and chills	Common and often severe	Mild, if any
Tiredness	Marked, can last for weeks	Mild
Runny or blocked nose, sneezing	Sometimes	Common
Complications	Pneumonia, worsening of asthma, heart disease or diabetes	Rare

Why do you need a flu vaccine every year?

• The virus keeps changing. Every year the World Health Organization reviews which strains are circulating, and manufacturers update the vaccine to match.
• Protection fades. Antibody levels drop over the months after vaccination, so last year’s dose won’t fully protect you this year.
• Malaysia has flu all year. Unlike countries with a winter flu season, influenza circulates year-round in Malaysia, with peaks (often around mid-year and towards the end of the year). Staying up to date matters more than waiting for a particular month.

Malaysia can use either the Northern or Southern Hemisphere formulation, whichever is the most recent. Your clinic will give you the current one.

Who should get the influenza vaccine?

The Ministry of Health recommends the flu vaccine every year for everyone, especially people at high risk:

• adults aged 60 and above
• pregnant women, at any stage of pregnancy. It also protects the baby during the first months of life.
• children from 6 months to 5 years
• people with long-term conditions: diabetes, asthma or COPD, heart disease, kidney or liver disease, obesity, or a weakened immune system
• healthcare workers and carers of older people, babies or people with chronic illnesses
• pilgrims and travellers, especially those going on Umrah or Hajj. For Malaysian Hajj pilgrims in high-risk groups, the flu vaccine is compulsory.

Since February 2025, MOH has offered free flu vaccination at selected government clinics to people aged 60 and above who have at least one listed chronic disease.

Flu vaccines available in Malaysia

The flu vaccines used in Malaysian clinics, such as Vaxigrip and Influvac, are inactivated vaccines given as an injection into the upper arm. Depending on the season’s formulation, they protect against three or four strains of influenza A and B. WHO stopped recommending one of the B strains (B/Yamagata) from 2024, so newer vaccines are moving to three strains.

• Adults and children aged 9 and above: one dose a year.
• Children aged 6 months to 8 years having a flu vaccine for the first time: two doses, at least four weeks apart. After that, one dose a year.

When should you get it?

Any time you’re due, there’s no wrong month in Malaysia. Two things to keep in mind:

• Allow two weeks for protection to build up, so get it at least two weeks before travel, a pilgrimage or a big family gathering.
• If you’re pregnant, you can have it in any trimester. Many doctors suggest getting it as soon as the current vaccine is available.

Side effects and safety

Most people have no side effects, or mild ones that pass within one to two days:

• soreness, redness or swelling in the arm
• a low-grade fever, headache or muscle aches
• feeling tired

A mild fever after the flu vaccine is the immune system responding, not influenza. Rest, drink fluids and take paracetamol if needed. Serious allergic reactions are very rare.

Tell the doctor before vaccination if you:

• had a severe allergic reaction to a flu vaccine before
• have ever had Guillain-Barré syndrome
• are unwell with a fever today. You’ll usually be asked to wait until you recover.

An egg allergy is no longer a reason to skip the vaccine, but mention it. Babies under 6 months can’t be vaccinated. Vaccinating the people around them and the mother during pregnancy protects them instead.

The flu vaccine can be given at the same visit as other vaccines, including the pneumococcal vaccine.

How much does a flu vaccine cost in Malaysia?

Prices vary by brand and clinic. Some employers and insurers cover it, so check your panel or TPA benefits, and ask the clinic for the current price before your visit. If you’re 60 or older with a chronic disease, ask whether you qualify for MOH’s free programme.

Frequently asked questions

How long does the influenza vaccine last?

Protection starts about two weeks after the injection and fades over the following months. Flu viruses also change every year, so a yearly dose is recommended.

Can the flu vaccine give me flu?

No. The flu vaccines used in Malaysia are inactivated and contain no live virus. A sore arm or mild fever for a day or two is your immune system responding, not influenza.

Is it normal to have a fever after the influenza vaccine?

A low-grade fever, headache or aches for one to two days is a common, harmless reaction. Rest, drink fluids and take paracetamol if needed. See a doctor if the fever is high or lasts longer.

Can pregnant women get the flu vaccine?

Yes. The flu vaccine is recommended in any trimester. It protects the mother, who is at higher risk of severe flu, and passes protection to the baby for the first months after birth.

Can I take the influenza vaccine twice a year?

Most people need one dose a year. Children under 9 having their first flu vaccine need two doses four weeks apart. Some high-risk people or frequent travellers may be advised to get the newer formulation about six months later. Ask your doctor.

How much does a flu vaccine cost in Malaysia?

It depends on the brand and the clinic, and some employers and insurers cover it. Ask the clinic for the current price. People aged 60 and above with a chronic disease may qualify for free vaccination at selected government clinics.

Can I get the flu and pneumococcal vaccines together?

Yes. They can be given at the same visit, one in each arm.
