A new study estimates vaccines prevented between 4000 and 12,000 deaths during the Omicron phase of the Covid-19 pandemic.

The paper, published in the medical journal Vaccine, models scenarios with different levels of vaccine coverage in the 18 months from January 2022.

The authors say the elimination strategy meant most people were able to be vaccinated before being exposed to the virus.

The researchers say it meant there were between 34,000 and 56,000 fewer hospitalisations over the period.
