This medicine is subject to additional monitoring, which will expedite 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 prospect thoroughly before your child receives this vaccine, because it contains important information for your child.

• Keep this prospect, as you may need to read it again.
• If you have any doubts, 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 adverse effects that do not appear in this prospect. See section 4.

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

Comirnaty KP.2 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.

Since Comirnaty KP.2 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 KP.2 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 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 lining 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 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 KP.2 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 KP.2 may be lower in immunocompromised individuals. If your child is immunocompromised, they may receive additional doses of Comirnaty KP.2. In these cases, your child should continue to take 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.

Children

Comirnaty KP.2 3 micrograms/dose concentrate for injection is not recommended for use in children under 5 to 11 years of age.

Pediatric formulations are available for children aged 5 to 11 years. For more information, see the prospectus for other formulations.

It is not recommended to use the vaccine in infants under 6 months of age.

Other medications and Comirnaty KP.2

Inform your child's doctor or pharmacist if your child is using, has used recently, or may need to use any other medication or has received any other vaccine recently.

Pregnancy and breastfeeding

Comirnaty KP.2 3 micrograms/dose concentrate for injection is not indicated for individuals over 5 years of age.

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 engage in 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 KP.2 with a yellow stopper after dilution in the form of an injection of 0.3 ml in a thigh muscle. If your child is an infant or a child 1 year of age or older, they will receive Comirnaty KP.2 with a yellow stopper after dilution in the form of an injection of 0.3 ml in 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 required 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 KP.2 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 KP.2.

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 required as a primary schedule. Your child should only receive the primary schedule once.

If you have any other questions about the use of Comirnaty KP.2, ask your child's doctor, pharmacist, or nurse.
