Q

What are Risks factors for Severe COVID 19?

A

Unvaccinated people are at higher risk of severe illness compared with vaccinated people

Most (75%) vaccinated people with severe COVID-19 illness have multiple risk factors:
– Older age (most ≥65 years, but with risk increasing with age)
– Underlying medical conditions (with risk increasing with the number of underlying conditions)

Antiviral drugs can help reduce the risk of severe illness in people at higher risk, regardless of vaccination status
