COVID-19 booster shots 'not optional' for people with breast cancer

People with breast cancer are being urged to get a COVID-19 booster shot as soon as possible, with those undergoing breast cancer treatment eligible for the dose much earlier than others.

The Breast Cancer Network Australia (BCNA) and the Australian government are advising a booster shot is essential for people with breast cancer.

Breast Cancer Network CEO Kirsten Pilatti said cancer treatment compromised the immune system, making the person more vulnerable to suffering severe complications if they got COVID-19.

"If you have breast cancer a third vaccine is not an optional extra, it is as important as the first and second doses," she said.

"We know that those who are immunocompromised may not respond as well to the vaccines resulting in a weaker defence against COVID -19."

Federal Health and Aged Care Minister Greg Hunt agreed "the medical experts recommend that people who are severely immunocompromised should receive a third dose".

"I encourage all those who are eligible to speak to their medical professional, especially if your health or the health of a loved one is compromised," he said.

Anyone on active treatment with chemotherapy, hormone therapy or radiotherapy is eligible to receive a third COVID-19 vaccine two months after their second vaccination.

The general Australian population must wait six months between a second and third dose of a COVID-19 vaccination.

It is recommended that the third vaccine be an mRNA vaccine (Pfizer or Moderna), regardless of what brand a person had for their first two doses.

Individuals should contact their health professional with any concerns or call BCNA's Helpline on 1800 500 258.
