Getting the flu vaccine

The flu vaccine is a safe and effective vaccine. It helps to protect you from flu.

The best time to get the flu vaccine is before the flu season starts. It's available from October to April each year.

Where to get the flu vaccine

You can get a flu vaccine from your GP surgery or pharmacy.

You can get the flu vaccine where you live if you:

  • live in a nursing home
  • are housebound

How it's given

For adults, the flu vaccine is given as an injection into your arm.

Children get the flu vaccine as a spray into their nose (nasal spray).

Who can get a free flu vaccine

You can get a free flu vaccine if you are:

  • age 60 and older
  • age 2 to 17
  • a healthcare worker
  • pregnant
  • living in a nursing home or other long-term care facility
  • in regular contact with pigs, poultry or waterfowl
  • someone with a health condition that puts you at higher risk of flu (age 6 months and older)
  • living with someone who has a health condition that puts them at higher risk of flu
  • a carer for someone who has a health condition that puts them at higher risk of flu
Health conditions that put you at higher risk of flu

People with these conditions can get a free flu vaccine:

  • chronic heart disease, including acute coronary syndrome
  • chronic liver disease
  • chronic kidney failure
  • chronic respiratory disease, including chronic obstructive pulmonary disease (COPD), cystic fibrosis, moderate or severe asthma, or bronchopulmonary dysplasia

  • children on long-term aspirin therapy
  • serious mental health conditions
  • any condition that can compromise respiratory function, such as spinal cord injury, seizure disorder or other neuromuscular disorder, especially people also attending special schools or day centres

There may be people with other health conditions that are recommended a flu vaccine. You can talk to your GP (doctor) or pharmacist about this.

Who is a carer?

A carer is someone who provides an ongoing, significant level of care to someone who needs care in the home due to illness, disability or frailty.

If you cannot get a free flu vaccine

If you cannot get a free flu vaccine, you can still get one at a pharmacy or GP. But you will need to pay for it.

When it starts to work

It takes 2 weeks for the vaccine to work. It should protect you for the whole flu season.

Side effects

After the vaccine, you may have some mild side effects.

These may include:

If you have any of these side effects, rest and take paracetamol.

Serious side effects

Serious side effects such as a severe allergic reaction are rare.

In very rare cases Guillain-Barré syndrome (GBS) has been reported.

GBS is a condition that affects the nerves in the body and causes nerve inflammation. It can can cause pain, numbness, muscle weakness and difficulty walking.

You are far more likely to get Guillain-Barré syndrome from having the flu than from the flu vaccine.

Reporting side effects

If you or your child get side effects from a vaccine, you can report it to the Health Products Regulatory Authority (HPRA). Your doctor, nurse, pharmacist or a family member can also report the side effect to the HPRA.

Report any harmful effects to the Health Products Regulatory Authority - hpra.ie

Flu vaccine and COVID-19 vaccine

The flu vaccine and the COVID-19 vaccine are 2 separate vaccines.

You can get can both at the same time if you are recommended a COVID-19 vaccine.
