An elderly woman with pre-existing medical conditions has died hours after receiving her COVID-19 vaccine in a Queensland aged care home.

It is understood the 82-year-old received a dose of the Pfizer vaccine at the Springwood Yurana Aged Care Facility on Wednesday, before she died in the afternoon.

Chief Medical Officer Paul Kelly said "at this stage there are no signs of any causal link".

"Any event that happens following vaccination is fully investigated," Professor Kelly said.

"Sadly more than 1000 people pass in aged care every week. It is inevitable, as the head of the TGA has noted, that this will include people who have been recently vaccinated.

"It can be expected that older and more frail people in an aged care setting may pass away due to progression of underlying disease or natural causes, this does not mean the vaccine has contributed to this."

The woman had a lung condition, according to the Courier Mail.

It comes as authorities investigate whether a Victorian man's rare blood clotting disorder was caused by his AstraZeneca jab.

The man received the vaccine on March 22.

A small number of people in Europe and the United Kingdom have presented with the blood clotting disorder but a causal link with the AstraZeneca vaccine is yet to be established.
