This medicine is subject to additional monitoring, which will facilitate the detection of new information about its safety. You can contribute by reporting any adverse effects your child may experience. The final part of section 4 includes information on how to report these adverse effects.

Read this product information carefully before your child receives this vaccine, as it contains important information for your child.

• Keep this product information, as you may need to refer to it again.
• If you have any questions, consult your child's doctor, pharmacist, or nurse.
• If your child experiences adverse effects, consult your child's doctor, pharmacist, or nurse, even if they are not listed in this product information. See section 4.

Comirnaty JN.1 is a vaccine used to prevent COVID-19 caused by SARS-CoV-2.

Comirnaty JN.1 3 microgram/dose concentrated for injection is administered to infants and children between 6 months and 4 years of age.

The vaccine causes the immune system (the body's natural defenses) to produce antibodies and blood cells that fight the virus, thereby providing protection against COVID-19.

Because Comirnaty JN.1 does not contain the virus to produce immunity, it cannot cause COVID-19 in your child.

This vaccine must be used in accordance with official recommendations.

Comirnaty JN.1 should not be administered

• if your child is allergic to the active ingredient or to any of the other components of this medication (listed in section 6).

Warnings and precautions

Consult with your child's doctor, pharmacist, or nurse before your child receives the vaccine if your child:

• has ever had a severe allergic reaction or breathing problems after receiving any other vaccine or after receiving this vaccine in the past;
• is anxious about the vaccination process or has fainted at any time after receiving an injection with a needle;
• has a serious illness or a high fever infection. However, your child may be vaccinated if they have a mild fever or an upper respiratory tract infection such as a cold;
• has a bleeding disorder, easily forms bruises, or uses a medication to prevent blood clotting;
• has a weakened immune system due to a disease such as HIV infection or a medication, such as corticosteroids, that affects the immune system.

There is a higher risk of myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the outer layer of the heart) after vaccination with Comirnaty (see section 4). These conditions may appear a few days after vaccination and have occurred mainly within 14 days. They have been observed more frequently after the second dose of vaccination, and more frequently in young males. The risk of myocarditis and pericarditis appears to be lower in children aged 5 to 11 years than in those aged 12 to 17 years. Most cases of myocarditis and pericarditis recover. Some cases required intensive care support and fatal cases have been observed. After vaccination, be alert to signs of myocarditis and pericarditis, such as difficulty breathing, palpitations, and chest pain, and seek immediate medical attention if they appear.

Like any vaccine, Comirnaty JN.1 may not protect all people who receive it completely, and it is not known how long your child will be protected.

The efficacy of Comirnaty may be lower in immunocompromised individuals. If your child is immunocompromised, they may receive additional doses of Comirnaty. In these cases, your child should continue to follow physical precautions to help prevent COVID-19. Additionally, your child's close contacts should be vaccinated as appropriate. Discuss individual recommendations with your child's doctor.

Driving and operating machinery

Some of the vaccine effects mentioned in section 4 (Possible adverse effects) may temporarily affect your child's ability to operate machinery or perform activities such as riding a bicycle. Wait for these effects to disappear before resuming activities that require your child's full attention.

If your child is an infant between 6 months and less than 12 months of age, they will receive Comirnaty JN.1 with ayellow stopperafter dilution in the form of an injection of0.3 mlin a thigh muscle. If your child is an infant or a child 1 year of age or older, they will receive Comirnaty JN.1 with ayellow stopperafter dilution in the form of an injection of0.3 mlin a thigh muscle or in an arm muscle.

If your child has not completed a primary vaccination schedule for COVID-19 or has not had COVID-19 previously, they will receive a maximum of three injections (the total number of doses needed as a primary schedule). It is recommended to receive the second dose 3 weeks after the first dose, followed by a third dose at least 8 weeks after the second dose, to complete the primary schedule.

If your child has previously completed a primary vaccination schedule for COVID-19 or has had COVID-19, they will receive 1 injection. If your child has previously received a COVID-19 vaccine, they should not receive a dose of Comirnaty JN.1 until at least 3 months after the most recent dose.

If your child turns 5 years of age between doses of the primary schedule, they must complete the primary schedule with the same dose level of 3 micrograms.

If your child is immunocompromised, they may receive additional doses of Comirnaty JN.1.

Interchangeability

Your child may receive any previous or current Comirnaty vaccine for the primary schedule. Your child should not receive more than the total number of doses needed as a primary schedule. Your child should only receive the primary schedule once.

If you have any other questions about the use of Comirnaty JN.1, ask your child's doctor, pharmacist, or nurse.
