What is Nuvaxovid?

What is Nuvaxovid used for?

How Nuvaxovid works

Nuvaxovid is a recombinant vaccine. It contains a modified, harmless version of the "spike protein" found on the COVID-19 virus.

Your immune system recognizes that this spike protein doesn't usually belong in your body. This leads your immune system to make antibodies against the protein. These antibodies tell other immune cells to get rid of the protein from the body.

Afterwards, your immune system remembers what the COVID spike protein looks like. So if you get exposed to COVID, your immune system is ready to fight and protect you from getting very sick.

Pharmacist tips for Nuvaxovid

pharmacist
  • Nuvaxovid is given as an injection into the muscle by a healthcare professional. You can usually get the vaccine at a medical office, health clinic, or pharmacy.
  • Sit down while you're getting Nuvaxovid. This helps prevent you from getting hurt if you faint after getting your vaccine. Depending on how you feel after, the healthcare professional might ask you to stay a little longer to make sure you're okay.
  • Nuvaxovid can cause mild discomfort, pain, or swelling where you got the shot. To help with these side effects, you can hold a cool, wet washcloth over the area where you got vaccinated. Moving your arm around can also help. These side effects should go away in a few days. But call a healthcare professional if they get worse or don't go away.
  • Most other side effects from Nuvaxovid are mild. They can include tiredness, headache, and muscle aches. These usually last couple days. Try to take it easy for the rest of the day. Drink plenty of water and dress in light clothing to avoid overheating if you have a fever. But if you don't feel better in a few days, call a healthcare professional for guidance.
  • Don't take over-the-counter medications before getting Nuvaxovid to try to prevent side effects. This includes ibuprofen (Advil) and acetaminophen (Tylenol). We don't know if taking these medications before getting Nuvaxovid could affect how well the vaccine works.
  • After getting Nuvaxovid, talk to a healthcare professional about which medications are safe to take if you need help managing side effects.
  • Even if you get vaccinated with Nuvaxovid, it's possible you can still get COVID-19. But the vaccine helps lower your risk of getting very sick. To help protect yourself, wash your hands often and avoid touching your eyes, nose, and mouth. Talk with a healthcare professional about other ways to help prevent getting sick.

Risks and warnings for Nuvaxovid

Nuvaxovid can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Allergic reaction

Allergic reactions to Nuvaxovid are possible. This can include anaphylactic reactions and can sometimes be very serious. Signs can include hives; shortness of breath; or swelling of the face, lips, or tongue. Get medical help or call 911 right away if this happens during or after you get vaccinated with Nuvaxovid.

Heart inflammation (swelling)

Although very rare, Nuvaxovid might raise the risk of heart inflammation. This includes myocarditis (swelling of the heart muscle) and pericarditis (swelling of the lining around the heart). These problems were reported in a very small number of people during studies.

Get medical help if you have possible signs of heart inflammation after getting Nuvaxovid. Watch out for chest pain, shortness of breath, or a racing heart.

Possible fainting after vaccination

Some people have fainted soon after getting vaccines given as an injection into the muscle. Tell the healthcare professional if you've ever fainted after getting vaccinated. They can keep a close eye on you for about 15 minutes after you get Nuvaxovid to make sure you're okay. To prevent getting hurt if you faint, it's best to sit down to get your shot and while the care team is watching you.

Lowered response to Nuvaxovid in people with a weakened immune system

  • Risk factors: Medical conditions that weaken the immune system | Taking medications that lower the activity of the immune system

Nuvaxovid might not work as well for people with a weakened immune system. This means they could still get very sick from COVID-19, even after getting the vaccine.

Before getting vaccinated, tell your care team about your health problems and any medications you take. Some conditions, like human immunodeficiency virus (HIV) and cancer, can weaken the immune system. And some medications, like long-term steroid use and transplant medications, can also make your immune system weaker.

If you have a weak immune system, keep taking steps to protect yourself from COVID. Talk to a healthcare professional about more ways to prevent getting sick.
