1. What is Spikevax bivalent Original/Omicron BA.4-5 and what is it used for

Spikevax XBB.1.5 is a vaccine used to prevent COVID-19 caused by the SARS-CoV-2 virus. It is administered to adults and children from 6 years of age and older. The active substance of Spikevax XBB.1.5 is mRNA that encodes the spike protein of the SARS-CoV-2 virus. The mRNA is encapsulated in lipid nanoparticles SM-102.

Because Spikevax XBB.1.5 does not contain the virus, it cannot give you COVID-19.

How the vaccine works

Spikevax XBB.1.5 stimulates the body's natural defenses (immune system). The vaccine works by making the body produce protection (antibodies) against the virus that causes COVID-19. Spikevax XBB.1.5 uses a substance called messenger ribonucleic acid (mRNA) to carry instructions that the body's cells can use to produce the spike protein that is also found in the virus. Then, the cells make antibodies against the spike protein to help fight the virus. This will help protect you against COVID-19.

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

The vaccine must not be administered ifyou 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 you are given Spikevax XBB.1.5 if:

  • you have previously had a severe, life-threatening allergic reactionafter any other vaccine or after receiving Spikevax (original) in the past.
  • you have a very weak or damaged immune system.
  • you have ever fainted after any injection with a needle.
  • you have a bleeding disorder.
  • you have a high fever or a severe infection; however, you can be vaccinated if you have a mild fever or an upper respiratory tract infection such as a cold.
  • you have any serious illness.
  • you have injection-related anxiety.

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 Spikevax (see section 4).

These disorders can occur a few days after vaccination and have mainly occurred within 14 days. They have been observed more frequently in young males and, more frequently, after the second dose of vaccination than after the first.

Most cases of myocarditis and pericarditis recover. Some of the cases required intensive care and fatal cases have been observed.

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.

If you are in any of the above situations (or are unsure), talk to your doctor, pharmacist or nurse before you are given Spikevax XBB.1.5.

Exacerbations of capillary leak syndrome

Some cases of exacerbation of capillary leak syndrome (which causes fluid to leak out of small blood vessels or capillaries, resulting in rapid swelling of the arms and legs, sudden weight gain and feeling of fainting and low blood pressure) have been reported after vaccination with Spikevax (original). If you have had previous episodes of capillary leak syndrome, talk to your doctor before you receive Spikevax XBB.1.5.

Duration of protection

As with any vaccine, the third dose of Spikevax XBB.1.5 may not fully protect all people who receive it and it is not known how long you will be protected.

Children

Spikevax XBB.1.5 is not recommended for use in children under 6 months.

Other medicines and Spikevax XBB.1.5

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Spikevax XBB.1.5 may affect the way other medicines work, and other medicines may affect the way Spikevax XBB.1.5 works.

People with weakened immune systems

The efficacy of Spikevax XBB.1.5 may be lower in people with weakened immune systems. In these cases, you should continue to maintain physical precautions to avoid COVID-19. Moreover, people close to you should be vaccinated as appropriate. Consult your doctor for individual recommendations.

Pregnancy and breastfeeding

If you are pregnant or think you may be pregnant, tell your doctor, nurse or pharmacist before you receive this vaccine. There is no data yet on the use of Spikevax XBB.1.5 during pregnancy. However, a large amount of observational data on pregnant women vaccinated with Spikevax (original) during the second and third trimester has not shown adverse effects on pregnancy or the newborn. Although data on pregnancy outcomes after vaccination during the first trimester are limited, no increased risk of spontaneous abortion has been observed. Since the differences between the two products are limited to the sequence of the spike protein in the vaccine and there are no clinically relevant differences, Spikevax XBB.1.5 can be used during pregnancy.

There is no data yet on the use of Spikevax XBB.1.5 during breastfeeding.

However, no effects on breastfed infants/children are expected. Data from women during breastfeeding after vaccination with Spikevax (original) have not shown a risk of adverse effects in breastfed infants/children. Spikevax XBB.1.5 can be administered during breastfeeding.

Driving and using machines

Do not drive or use machines if you feel unwell after vaccination. Wait until these effects have passed before driving or using machines.

Spikevax XBB.1.5 contains sodium

This medicinal product contains less than 1 mmol of sodium (23 mg) per dose; this is essentially “sodium-free”.
