Arexvy is a vaccine that helps protect adults aged 60 years and olderfrom a virus called the “respiratory syncytial virus” (RSV).

Arexvy also helps protect against RSV in adults aged 50 to 59 years with a higher risk of contracting the disease caused by RSV.

RSV is a respiratory virus that spreads very easily.

• RSV can cause lower respiratory tract disease - infections in the lungs and other parts of the body that help you breathe.

RSV infection typically produces mild symptoms similar to those of a cold in healthy adults. However, it can also:

• produce more severe respiratory diseases and complications, such as pneumonia,in older adultsand in adults with underlying conditions
• exacerbate some diseases, such as respiratory or cardiac diseases

in the long term.

How Arexvy works

Arexvy helps your body's natural defenses generate special antibodies and white blood cells. These protect you against RSV.

Arexvy does not contain the virus. This means it cannot cause an infection.

Do not use Arexvy

• if you are allergic to the active substances or to any of the other components of this vaccine (listed in section 6).

Do not use Arexvy if any of the above applies to you. If you are unsure, consult your doctor or pharmacist.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting Arexvy if:

• you have ever had a severe allergic reaction after an injection of any other vaccine
• you have a severe infection with high temperature (fever). If this happens, the vaccination may be delayed until you feel better. A minor infection, such as a cold, should not be a problem, but consult your doctor first
• you have a bleeding disorder or bruise easily
• you fainted after a previous injection. Fainting can occur before or after any injection with a needle.

If any of the above applies to you, or if you are unsure, consult your doctor or pharmacist before Arexvy is administered to you.

As with all vaccines, Arexvy may not protect all vaccinated individuals completely.

Other medicines/vaccines and Arexvy

Inform your doctor or pharmacist if:

• you are taking, have taken recently, or may need to take any other medicine. This includes medicines obtained without a prescription
• you have received recently any other vaccine.

Arexvy can be administered at the same time as a flu vaccine.

If Arexvy is administered at the same time as another injectable vaccine, a different injection site will be used for each vaccine, i.e., a different arm for each injection.

Some of the effects mentioned in section 4 “Possible side effects” (e.g., feeling tired) may temporarily affect your ability to drive or use machines. Do not drive or use machines if you do not feel well.
