What is Nuvaxovid?

Nuvaxovid is a vaccine used to protect against COVID-19. Nuvaxovid is for people who are:

  • 65 years of age and older, or
  • 12 years through 64 years of age, at high risk for severe COVID-19.

Vaccination with Nuvaxovid may not protect all people who receive the vaccine. Nuvaxovid cannot give you or your child COVID-19.

Nuvaxovid does not contain SARS-CoV-2, the virus that causes COVID-19. Unlike mRNA vaccines, Nuvaxovid contains a recombinant spike protein combined with Matrix-M adjuvant to enhance the immune response.

Who should not get Nuvaxovid?

You or your child should not get Nuvaxovid if you or your child had:

  • a severe allergic reaction after a previous dose of Nuvaxovid or Novavax COVID-19 Vaccine, Adjuvanted
  • a severe allergic reaction to any ingredient of this vaccine (see What are the ingredients in Nuvaxovid?)

Tell your vaccination provider about all of your or your child's medical conditions, including if you or your child:

  • has any allergies
  • had a severe allergic reaction after receiving a previous dose of any COVID-19 vaccine
  • have had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart)
  • have a fever
  • have a bleeding disorder or are on a blood thinner
  • are immunocompromised or are on a medicine that affects your immune system
  • are pregnant or plan to become pregnant
  • are breastfeeding
  • have received any other COVID-19 vaccine
  • have ever fainted in association with an injection.

How is Nuvaxovid given?

Nuvaxovid is given as an injection into the muscle.

Tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take.

There is a remote chance that Nuvaxovid could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose. For this reason, your vaccination provider may ask you or your child to stay at the place where you or your child received the vaccine for monitoring after vaccination. Signs of a severe allergic reaction can include:

  • Difficulty breathing
  • Swelling of your face and throat
  • A fast heartbeat
  • A bad rash all over your body
  • Dizziness and weakness.

Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received Nuvaxovid or Novavax COVID-19 Vaccine, Adjuvanted. The chance of having this occur is very low. You should seek medical attention right away if you or your child has any of the following symptoms after receiving the vaccine:

  • Chest pain
  • Shortness of breath
  • Feelings of having a fast-beating, fluttering, or pounding heart.

Side effects that have been reported in clinical trials with Nuvaxovid include:

  • Myocarditis (inflammation of the heart muscle)
  • Pericarditis (inflammation of the lining outside the heart)
  • Injection site reactions: pain/tenderness, swelling, redness, and itching
  • General side effects: fatigue or generally feeling unwell, muscle pain, headache, joint pain, nausea, vomiting, fever, chills
  • Allergic reactions such as hives and swelling of the face
  • Swollen lymph nodes

Side effects that have been reported in post-authorization use with Nuvaxovid include:

  • Severe allergic reactions
  • Myocarditis (inflammation of the heart muscle)
  • Pericarditis (inflammation of the lining outside the heart)
  • Paresthesia (unusual feeling in the skin, such as tingling or a crawling feeling), hypoesthesia (decreased feeling or sensitivity, especially in the skin)

These may not be all the possible side effects of Nuvaxovid. Ask your healthcare provider about any side effects that concern you.

Report vaccine side effects to the FDA and the Centers for Disease Control and Prevention (CDC) Vaccine Adverse Event Reporting System (VAERS) at 1-800-822-7967 or https://vaers.hhs.gov/reportevent.html.

Frequently asked questions

How does Nuvaxovid differ from mRNA vaccines?
Nuvaxovid contains purified spike protein with an adjuvant, while mRNA vaccines instruct cells to make the protein.
Can I get Nuvaxovid if I'm not high-risk?
Nuvaxovid is only approved for people 65+ or those 12-64 with high-risk conditions.
Can you become immune to COVID-19?
Immunity after COVID-19 varies from person to person and decreases over time. You can get COVID-19 more than once, especially as new variants emerge. Protection from a past infection or vaccination can still lower your risk of severe illness. Updated COVID-19 vaccines can help boost your immune protection. Continue reading
