1. What is Comirnaty and what is it used for

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

Comirnaty 30 micrograms/dose dispersion for injection is administered to adults and adolescents from 12 years of age.

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

Because Comirnaty does not contain the virus to produce immunity, it cannot give you COVID-19.

2. What you need to know before you receive Comirnaty

Comirnaty must not be administered

  • if you are allergic to the active substance or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to 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 receiving Comirnaty in the past;
  • you are nervous about the vaccination process or have fainted after an injection with a needle;
  • you have a severe illness or infection with high fever. However, you can 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 are taking a medicine to prevent blood clots;
  • you have a weakened immune system due to a disease such as HIV or due to a medicine, 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 disorders can occur within a few days of vaccination and have mainly occurred 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 between 5 and 11 years of age than in those between 12 and 17 years of age. After vaccination, you should be alert to the signs of myocarditis and pericarditis, such as difficulty breathing, palpitations, and chest pain, and should seek immediate medical attention if they occur.

As with any vaccine, Comirnaty may not fully protect all people who receive it, and it is not known how long you will be protected.

You may receive a booster dose of Comirnaty. The effectiveness of Comirnaty, even after a booster dose, may be lower in immunocompromised individuals. In these cases, you should continue to maintain physical precautions to help prevent COVID-19. Additionally, your close contacts should be vaccinated as appropriate. Discuss individual recommendations with your doctor.

Children

Comirnaty 30 micrograms/dose dispersion for injection is not recommended for use in children under 12 years of age.

A pediatric presentation is available for infants and children from 6 months to 4 years of age. For more information, see the package leaflet for Comirnaty 3 micrograms/dose concentrate for dispersion for injection.

A pediatric presentation is available for children from 5 to 11 years of age (i.e., from 5 to less than 12 years of age). For more information, see the package leaflet for Comirnaty 10 micrograms/dose concentrate for dispersion for injection.

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

Other medicines and Comirnaty

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicine or have recently received any other vaccine.

Pregnancy and breastfeeding

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

Comirnaty can be used during pregnancy. A large amount of information on pregnant women vaccinated with Comirnaty during the second and third trimesters has not shown negative effects on pregnancy or on the newborn. Although information on the effects on pregnancy or the newborn after vaccination during the first trimester is limited, no change in the risk of spontaneous abortion has been observed.

Comirnaty can be used during breastfeeding.

Driving and using machines

Some of the effects of vaccination mentioned in section 4 (Possible side effects) may temporarily affect your ability to drive or use machines. Wait until these effects have disappeared before driving or using machines.

3. How Comirnaty is administered

Comirnaty is administered as an injection of 0.3 ml into a muscle of the arm. You will receive two injections.

A second dose of the same vaccine is recommended 3 weeks after the first dose to complete the vaccination schedule.

If you are immunocompromised, you may receive a third dose of Comirnaty at least 28 days after the second dose.

A booster dose of Comirnaty can be administered at least 3 months after the most recent dose of a COVID-19 vaccine in individuals 12 years of age and older.

Consult your healthcare professional about eligibility for the booster dose and the timing of administration.

If you have any further questions on the use of Comirnaty, ask your doctor, pharmacist, or nurse.
