A senior doctor in regional South Australia has becomes the first Australian to receive the AstraZeneca COVID-19 vaccine.

Caroline Phegan, a GP consultant and head of the Riverland Mallee Coorong Local Health Network, received the jab at Murray Bridge Hospital this morning.

Dr Phegan said she was immunocompromised, and would therefore be especially vulnerable to the coronavirus.

She said she was excited to receive the inoculation and honoured to be the first in the country.

Dozens of fellow medical staff will receive the jab this week.

More to come.
