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 receiving this vaccine, as it contains important information for you.

• 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 30 microgramos/dose injectable dispersion is administered to adults and adolescents aged 12 years and older.

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 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.

Do not administer Comirnaty JN.1

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

Warnings and precautions

Consult your doctor, pharmacist, or nurse before receiving the vaccine if:

• you have ever had a severe allergic reaction or breathing problems after receiving any other vaccine or after this vaccine was administered in the past;
• you are anxious about the vaccination process or have fainted at any time after an injection with a needle;
• you have a serious illness or a high fever infection. However, you may be vaccinated if you have a mild fever or an upper respiratory tract infection such as a cold;
• you have a bleeding disorder, bruise easily, or use a medication to prevent blood clotting;
• you have 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 occur.

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

The efficacy of Comirnaty JN.1 may be lower in immunocompromised individuals. If you are immunocompromised, you may receive additional doses of Comirnaty JN.1. In these cases, you should continue to follow physical precautions to help prevent COVID-19.

Additionally, your close contacts should be vaccinated as appropriate. Discuss individual recommendations with your doctor.

Children

Comirnaty JN.1 30 microgram/dose injectable dispersion is not recommended for use in children under 12 years of age.

Pediatric formulations are available for infants 6 months of age and older and children under 12 years of age. For more information, see the prospectus for other formulations.

Comirnaty JN.1 is not recommended for use in infants under 6 months of age.

Other medications and Comirnaty JN.1

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication or have received any other vaccine recently.

Comirnaty JN.1 can be administered at the same time as a flu vaccine.

Pregnancy and breastfeeding

If you are pregnant or think you may be pregnant, inform your doctor, nurse, or pharmacist before receiving this vaccine.

No data are available on the use of Comirnaty JN.1 during pregnancy. However, a large amount of information on pregnant women vaccinated with the initially approved Comirnaty vaccine during the second and third trimesters has not shown negative effects on pregnancy or the newborn. Although information on effects after vaccination during the first trimester is limited, no change in the risk of spontaneous abortion has been observed. Comirnaty JN.1 can be used during pregnancy.

No data are available on the use of Comirnaty JN.1 during breastfeeding. However, no effects are anticipated in the newborn/baby. Data on women who were breastfeeding after vaccination with the initially approved Comirnaty vaccine have not shown a risk of adverse effects in newborn/baby. Comirnaty JN.1 can be used during breastfeeding.

Driving and operating machinery

Some of the effects of vaccination mentioned in section 4 (Possible adverse effects) may temporarily affect the ability to drive or operate machinery. Wait for these effects to disappear before driving or operating machinery.

Comirnaty JN.1 is administered as a 0.3 ml injection into a muscle of the arm.

You will receive 1 injection, regardless of whether you have previously received a COVID-19 vaccine.

If you have previously received a COVID-19 vaccine, you should not receive a dose of Comirnaty JN.1 until at least 3 months after the most recent dose.

If you are immunocompromised, you may receive additional doses of Comirnaty JN.1.

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

-------------------------------------------------------------------------------------------------------------------------

This information is intended for healthcare professionals only:

Administer Comirnaty JN.1 by intramuscular injection as a single dose of 0.3 ml regardless of the previous COVID-19 vaccination status.

For individuals who have previously received a COVID-19 vaccine, Comirnaty JN.1 should be administered at least 3 months after the most recent dose of a COVID-19 vaccine.

Additional doses may be administered in individuals who are severely immunocompromised.

Traceability

In order to improve the traceability of biological medicinal products, the name and batch number of the medicinal product administered must be clearly recorded.

Instructions for handling before use

Comirnaty JN.1 must be prepared by a healthcare professional using aseptic technique to ensure the sterility of the prepared dispersion.

• Check that the vial has a gray plastic closure cap and that the product name is Comirnaty JN.1 30 micrograms/dose dispersion for injection (for individuals aged 12 years and older).

• If the vial has a different product name on the label, consult the product's technical file or summary of product characteristics for that formulation.

• If the vial is stored frozen, it must be thawed before use. Frozen vials must be transferred to a refrigerated area between 2 °C and 8 °C to thaw. Ensure that the vials are completely thawed before use.

• Single-dose vials: a pack of 10 single-dose vials may take 2 hours to thaw.
• Multi-dose vials: a pack of 10 multi-dose vials may take 6 hours to thaw.

• When transferring vials to storage at 2 °C to 8 °C, update the expiration date on the box.

• Unopened vials may be stored for a maximum of 10 weeks at 2 °C to 8 °C ; do not exceed the printed expiration date (EXP).
• Alternatively, individual frozen vials may be thawed in 30 minutes at temperatures up to 30 °C.
• Before use, unopened vials may be stored for a maximum of 12 hours at temperatures up to 30 °C. Thawed vials may be handled in ambient light.

Preparation of 0.3 ml doses

• Mix the vials gently by inverting them 10 times before use. Do not shake.

• Before mixing, the thawed dispersion may contain amorphous particles of color between white and off-white.

• After mixing, the vaccine must have the appearance of a transparent to slightly opalescent dispersion without visible particles. Do not use the vaccine if it presents visible particles or a color change.

• Check if the vial is a single-dose vial or a multi-dose vial and follow the applicable handling instructions below:

• Single-dose vials

• Extract a single dose of 0.3 ml of vaccine.
• Discard the vial and any remaining volume.

• Multi-dose vials

• Multi-dose vials contain 6 doses of 0.3 ml each.
• Using aseptic technique, clean the stopper of the vial with a single-use antisepsis swab.
• Extract 0.3 ml of Comirnaty JN.1 for children aged 5 to 11 years.

To extract 6 doses from the same vial, use syringes and/or needles with low dead volume. The combination of syringe and needle with low dead volume must have a dead volume of 35 microliters or less. If conventional syringes and needles are used, there may not be enough volume to extract a sixth dose from the same vial.

• Each dose must contain 0.3 ml of vaccine.
• If the remaining volume in the vial is insufficient to provide a complete dose of 0.3 ml, discard the vial and any remaining volume.
• Record the appropriate time and date on the vial. Discard the unused vaccine 12 hours after the first puncture.

Disposal

The disposal of unused medicinal product and all materials that have been in contact with it will be carried out in accordance with local regulations.
