With more than 2,400 people currently in hospital, the Australian Technical Advisory Group on Immunisation (ATAGI) recommends Australians aged 16 years and older have a COVID-19 booster vaccine to ensure high levels of protection against severe disease and hospitalisation. A booster dose of the COVID vaccine, three months following the completion of the primary course can provide a similar level of protection against Omicron as two primary doses against Delta. 

Additionally, data shows that the booster dose renders milder side effects compared to the first 2 doses with less than 1% of people reporting the need for a medical consultation. 

This article explores the benefits of a booster vaccine compared to the primary 2 doses, the time frame recommendation for receiving a booster following COVID infection, and whether additional vaccine doses will be required in the future.
