Dosage to help prevent COVID-19

If your doctor prescribes Novavax to help prevent COVID-19, you’ll receive one or two injections, depending on your current vaccination status. Each injection contains 0.5 mL of Novavax and is considered one dose.
If you’ve already been vaccinated against COVID-19, your doctor will give you one Novavax dose at least 2 months after the date of your last COVID-19 vaccine. This is considered a “booster” dose. A booster is a shot that helps increase the effectiveness of a vaccine you’ve already received.
If you’ve never received a COVID-19 vaccine before, your doctor will give you two 0.5 mL Novavax doses. You’ll receive the second dose 3 weeks after the first.
If you have a weakened immune system, your doctor may decide to give you an additional 0.5 mL dose of Novavax at least 2 months after your last COVID-19 vaccine.
