Adults aged 18–64 years without a medical risk condition can consider COVID-19 vaccine every year

Adults aged 18–64 years who do not have medical conditions that increase their risk of severe disease can consider an annual dose of COVID-19 vaccine based on individual preference and a risk-benefit assessment. The risk of severe disease from COVID-19 is low in previously vaccinated healthy adults^4,5 and by now, most adults living in Australia have acquired immunity through multiple vaccination or infection events.

Risk-benefit considerations for vaccination may include:

• Age-related risk of COVID-19 and its complications: COVID-19 can occur at any age, but the risk of severe disease in adults increases with age.
• Potential risks associated with COVID-19 vaccination: Most adverse events following COVID-19 vaccination are mild to moderate and self-limited. Very rare but serious adverse events such as myocarditis and pericarditis have been reported with the highest incidence amongst adolescent and young adult males after a second mRNA vaccine dose.^6-8  
• Individual’s personal preferences: Personal attitudes towards preventing severe COVID-19 and related complications may influence decisions about vaccination.
