What to do to prepare for COVID-19

Make sure you're up to date with your COVID-19 vaccinations

Vaccination is the best way to protect yourself against COVID-19. Make sure you’re up-to-date with your vaccinations and have received all recommended doses (external link).

COVID-19 vaccines are safe and effective (external link).

Most people should receive 2 doses of COVID-19 vaccine for their primary course but if you are severely immunocompromised and aged 5 years and older, you should receive 3 doses for your primary course (external link).

Doses and booster vaccinations

People aged 5 years and older who are severely immunocompromised should receive 3 doses for their primary course (external link) of a COVID-19 vaccine, with the 3rd dose to be given 2 months after the 2nd dose.

People aged 16 years and older who are severely immunocompromised are also recommended to receive 2 additional booster doses.

The timing of booster vaccination doses for severely immunocompromised people is:

If you’re unsure how many doses you should have or need advice about the timing of vaccines around treatments, speak to your GP or healthcare professional.

If you have had COVID-19, wait 3 months after you recover before you receive your next dose.

Additional measures you can take

People with a weakened immune system may consider taking additional measures, including using high quality masks, working from home where possible (external link) and making alternate arrangements for work and school where necessary.

You can ask friends or family members to take a rapid antigen test (RAT) before catching up or visiting, continue to keep up good hygiene habits like washing hands and using hand sanitiser, and hold gatherings outside where possible.

Speak to your GP if you are concerned about COVID-19, particularly if you have a medical condition that puts you in a higher risk category. You can work with them to complete a COVID-19 care plan (external link) and ensure you have a COVID-19 kit.

You may be eligible for COVID-19 treatment with an antiviral medication (external link), depending on your age, existing medical conditions, when you were diagnosed with COVID-19 and the severity of your symptoms. Your GP can prescribe antiviral medication treatments.


With COVID-19 in the community, it is understandable if you are hesitant about masks not being required in some settings, especially if you have an underlying medical condition, or if there are people at risk of serious illness living in your household or family. You are strongly encouraged to wear a mask if you feel more comfortable doing so.

Wearing a well-fitting mask is a simple and effective precaution you can take to stay safe and minimise the spread of COVID-19.

It is a good idea to carry a mask when you leave home and wear one if you can't physically distance from others.
