Vaccination with JYNNEOS is expected to decrease the likelihood of infection, as well as the severity of infection should you become infected. It does not give complete immunity, nor will it prevent you from spreading the virus to others.

While a single dose of the vaccine is believed to give moderate protection after 2 weeks, it is very important to complete both doses in order to get the highest level of protection. Your second dose should be given 28 days after your first dose. However, a dose may be administered up to 4 days before the minimum interval of 28 days if necessary, as per CDC guidelines.

People who had a severe allergic reaction to a previous dose of the JYNNEOS vaccine or an ingredient in the vaccine (such as gentamicin, ciprofloxacin, or egg protein) should not receive the JYNNEOS vaccine.

Yes, you can receive the JYNNEOS monkeypox vaccine at the same time as the flu vaccine.

Yes, you can receive the JYNNEOS monkeypox vaccine and the COVID-19 vaccine during the same doctor's visit, as long as the COVID-19 vaccine is administered first.

As per CDC guidelines, COVID-19 vaccines may be delayed by 4 weeks if the JYNNEOS vaccine is given first. If you have any questions about the timing of your vaccinations, please contact your primary care physician. 

There will be no charge for the doses of the vaccine, but depending on insurance coverage, an administrative fee may be billed to your insurance.

Monkeypox is a rare but sometimes serious illness caused by a virus. It belongs to the same family as the smallpox virus. This illness is uncommon in the United States, but global travel has increased the risk of bringing diseases from other countries.

• Fever, headache, muscle aches, and feeling exhausted
• Swollen lymph nodes
• Skin sores that may look like pimples or blisters. They may be limited to one area or widespread. The sores can appear:
  • On your face or inside your mouth
  • On your shoulders, chest, belly, genital, or buttock area
  • On your hands and palms, or feet and soles

• Touching an infected person’s body or skin sores
• Touching an infected person’s clothes, bedsheets, or towels
• Touching an infected animal

For most people, monkeypox goes away on its own without treatment. Symptoms often last from two to four weeks. There is no treatment approved specifically for monkeypox. Some medicines used for smallpox may help prevent or treat monkeypox. Some people with severe symptoms may benefit from treatment. If you have symptoms of monkeypox, talk to your health care team, such as your primary care doctor. Getting medical help early is important for people with weakened immune systems.

You can take steps to protect yourself from this illness. Here’s how:

• Avoid close skin-to-skin contact with people who have a rash that looks like monkeypox.
• Do not kiss, hug, cuddle, or have sex with someone with this illness.
• Do not share plates, silverware, or cups with a person with this illness.
• Do not handle the bedding, towels, or clothing of a person with monkeypox.
• Wash your hands often with soap and water or use a hand sanitizer.

If you have a high risk for infection, you may be eligible for a monkeypox vaccine. Check with your health care team or clinic.

You may have a high risk if you:

• Have contact with someone who had a rash or sore that looks like monkeypox
• Have contact with someone diagnosed with monkeypox
• Have skin contact with friends who have had monkeypox
• Travel outside the United States to an area where monkeypox is more common
• Have contact with an animal that lived where monkeypox has been more common

• Stay home.
• Stay in a separate room or area from other family members and pets.

• You have symptoms that may be monkeypox.
• You might have had close contact with someone who has known or suspected monkeypox.
