1. What Spikevax XBB.1.5 is and what it is used for

Spikevax XBB.1.5 is a vaccine used to prevent COVID-19, a disease caused by the coronavirus SARS-CoV-2. It is administered to adults and children aged 6 months and older. The active substance of Spikevax XBB.1.5 is mRNA encoding the spike protein of SARS-CoV-2. The mRNA is encapsulated in lipid nanoparticles SM-102.
Since Spikevax XBB.1.5 does not contain the virus, it cannot cause COVID-19.
How the vaccine works
Spikevax XBB.1.5 stimulates the body's natural defenses (the immune system). The vaccine prompts the body to produce protection (antibodies) against the virus that causes COVID-19. Spikevax XBB.1.5 uses a substance called messenger ribonucleic acid (mRNA) to deliver instructions that the body's cells can use to produce the spike protein found on the virus. The cells then produce antibodies against the spike protein, helping to fight the virus. This helps protect against COVID-19.

2. What you need to know before receiving Spikevax XBB.1.5

The vaccine must not be administered if you are allergic to the active substance or to any of the
other components of this vaccine (listed in section 6).
Warnings and precautions
Talk to your doctor, pharmacist, or nurse before receiving Spikevax XBB.1.5 if:

  • you have previously had a severe, potentially life-threatening allergic reaction after any other vaccine injection or after administration of Spikevax (original)
  • you have a very weak or compromised immune system
  • you have previously fainted after an injection with a needle
  • you have a blood clotting disorder
  • you have a high fever or a serious infection; however, you may receive vaccination if you have a mild fever or a mild respiratory infection such as a cold
  • you have a serious illness
  • you suffer from anxiety related to injections

After vaccination with Spikevax, there is an increased risk of myocarditis (inflammation of the
heart) and pericarditis (inflammation of the outer lining of the heart) (see section 4).
These conditions may develop a few days after vaccination and have mainly occurred within 14 days.
They have been observed more frequently in young males and more often after the second dose than
after the first dose.
Most cases of myocarditis and pericarditis resolve. Some cases have required intensive therapy and fatal cases have been reported.
After vaccination, pay particular attention to signs of myocarditis and pericarditis, such as shortness
of breath, palpitations, and chest pain, and seek immediate medical advice if any of these symptoms
occur.
If you fall into any of the above categories (or if you have any doubts), talk to your doctor,
pharmacist, or nurse before receiving Spikevax XBB.1.5.
Recurrence of capillary leak syndrome (CLS)
There have been reports of recurrence of capillary leak syndrome following vaccination with Spikevax (original). This condition causes leakage of fluid from small blood vessels (capillaries), resulting in rapid swelling of the arms and legs, sudden weight gain, feeling faint, and low blood pressure. If you have previously experienced episodes of CLS, consult your doctor before administration of Spikevax XBB.1.5.
Duration of protection
As with any vaccine, an additional dose of Spikevax XBB.1.5 may not fully protect all individuals who receive it, and the duration of protection is not known.
Children
Spikevax XBB.1.5 is not recommended for children under 6 months of age.
Other medicines and Spikevax XBB.1.5
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other
medicines. Spikevax XBB.1.5 may affect how other medicines work, and other medicines may affect how Spikevax XBB.1.5 works.
Immunocompromised individuals
The effectiveness of Spikevax XBB.1.5 may be reduced in immunocompromised individuals. In
such cases, you should continue to take physical precautions to help prevent COVID-19.
If appropriate, your close contacts should also be vaccinated. Talk to your doctor about the recommendations most suitable for you.
Pregnancy and breastfeeding
If you are pregnant or suspect you may be pregnant, inform your doctor, nurse, or
pharmacist before receiving this vaccine. Data on the use of
Spikevax XBB.1.5 during pregnancy are not yet available. However, a large amount of data from women who received Spikevax (original) during the second and third trimesters of pregnancy have not shown any negative effects on pregnancy or the newborn. Although data on effects during pregnancy or on the newborn after vaccination in the first trimester are limited, no increased risk of spontaneous abortion has been observed. Since the differences between the two products involve only the spike protein in the vaccine and there are no clinically relevant differences, Spikevax XBB.1.5 may be used during pregnancy.
Data on the use of Spikevax XBB.1.5 during breastfeeding are not yet available.
However, effects on breastfed infants are not expected. Data from women who breastfed after vaccination with Spikevax (original) have not shown a risk of adverse events in breastfed infants. Spikevax XBB.1.5
may be administered during breastfeeding.
Driving and use of machines
Avoid driving or operating machinery if you do not feel well after vaccination. Wait until any side effects of the vaccine have subsided before driving or using machinery.
Spikevax XBB.1.5 contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per dose, i.e. essentially “sodium-free”.
