Long information

What is it and how is it used?

Celvapan is a vaccine to prevent influenza (flu) caused by A(H1N1)v 2009 virus

When a person is given the vaccine, the immune system (the body?s natural defense system) will produce its own protection (antibodies) against the disease. None of the ingredients in the vaccine can cause flu.

What do you have to consider before using it?

You should not receive Celvapan

  • if you previously had a sudden life-threatening allergic reaction to any ingredient of Celvapan or to any of the substances that may be present in trace amounts as follows: formaldehyde, benzonase, sucrose. Signs of an allergic reaction may include itchy skin rash, shortness of breath and swelling of the face or tongue.

If you are not sure, talk to your doctor or nurse before having this vaccine.

Take special care with Celvapan

  • if you have had any allergic reaction other than a sudden life-threatening allergic reaction to any ingredient contained in the vaccine, to formaldehyde, benzonase, or to sucrose. (see section 6. Further information).
  • if you have a severe infection with a high temperature (over 38°C). If this applies to you then your vaccination will usually be postponed until you are feeling better. A minor infection such as a cold should not be problem, but your doctor or nurse should advise whether you could still be vaccinated with Celvapan,
  • if you are having a blood test to look for evidence of infection with certain viruses. In the first few weeks after vaccination with Celvapan the results of these tests may not be correct. Tell the doctor requesting these tests that you have recently been given Celvapan,

In any of these cases, TELL YOUR DOCTOR OR NURSE, as vaccination may not be recommended, or may need to be delayed.

Please inform your doctor or nurse if you have a bleeding problem or bruise easily.

Allergic reactions (including anaphylaxis) have been reported following vaccination with Celvapan (see section 4 ?Possible Side Effects?).

Taking other medicines

Please tell your doctor or nurse if you are taking or have recently taken any other medicines, including medicines obtained without a prescription or have recently been given any other vaccine.

There is no information on administration of the vaccine Celvapan with other vaccines. However, if this cannot be avoided, the vaccines should be injected into separate limbs. In such cases, you should be aware that the side effects may be more intense.

Pregnancy and breast-feeding

Tell your doctor if you are pregnant, think you may be pregnant, or plan to become pregnant. You should discuss with your doctor whether you should receive Celvapan.

The vaccine may be used during breast-feeding.

Driving and using machines

Some effects mentioned under section 4. ?Possible side effects? may affect your ability to drive or use machines.


How is it used?

Your doctor or nurse will administer the vaccine in accordance with official recommendation. The vaccine will be injected into a muscle (usually in the upper arm).

Adults and elderly
A dose (0.5 ml) of the vaccine will be given.
A second dose of the vaccine should be given after an interval of at least three weeks.

Children and adolescents aged 6 months to 17 years of age
If it is considered that you or your child needs to be vaccinated, you/he/she may receive one dose of 0.5 ml vaccine and a second dose of 0.5 ml at least three weeks later.

Children aged less than 6 months
Vaccination is not currently recommended in this age group.

When Celvapan is given for the first dose, it is recommended that Celvapan (and not another vaccine against (H1N1)v) be given for the complete vaccination course.

What are possible side effects?

Like all medicines, Celvapan can cause side effects, although not everybody gets them.

Allergic reactions may occur following vaccination, in rare cases leading to shock. Doctors are aware of this possibility and have emergency treatment available for use in such cases.

In the clinical studies with a similar vaccine, most side effects were mild in nature and short term. The side-effects are generally similar to those related to the seasonal flu vaccine. There were fewer side effects after the second vaccination compared with the first. The most frequently occurring side effect was injection site pain, which was usually mild.

The frequency of possible side effects listed below is defined using the following convention: very common (affects more than 1 user in 10)
common (affects 1 to 10 users in 100)
uncommon (affects 1 to 10 users in 1,000)
rare (affects 1 to 10 users in 10,000)
very rare (affects less than 1 user in 10,000)

Side effects observed with Celvapan (H5N1)
The side effects listed below have occurred with Celvapan (H5N1) in clinical studies in adults, including the elderly:

Very common:

  • pain at the injection site, headache, fatigue (feeling tired)


  • runny nose and sore throat,
  • dizziness, vertigo (motion sickness)
  • sweating more than usual,
  • joint or muscle pain,
  • chills, malaise (generally feeling unwell), fever,
  • tissue hardening, redness, swelling or bruising at the injection site
  • nausea, vomiting, diarrhoea, stomach pain


  • numb, tingling or prickly skin,
  • dry throat,
  • swollen glands,
  • insomnia (difficulty sleeping), restlessness,
  • impaired perception of touch, pain, heat and cold, sleepiness,
  • conjunctivitis (an inflammation of the eye),
  • sudden hearing loss,
  • reduced blood pressure,
  • shortness of breath, cough, congestion of the nose,
  • rash, itching,
  • irritation at the injection site


  • ear pain, stiff arm

These side effects usually disappear within 1-2 days without treatment. If they persist, CONSULT YOUR DOCTOR.

  • Clinical Trials with Celvapan (H1N1)v

Safety findings after the first and second dose of vaccine given during an ongoing clinical trial of Celvapan (H1N1)v in adults and elderly (18 years of age and older) suggest a similar safety profile to that reported for influenza vaccines containing a H5N1 strain. Safety results from another ongoing Celvapan (H1N1)v study involving children and adolescents aged 3-17 years were similar to the findings of the adults and elderly trial. However, in the children?s trial injection site pain was reported at a higher rate (very common) than in adults, and both headache and fatigue were reported at a lower rate (common) than in adults. In children aged 3 to 8 years, fever after both the 1 st and 2 nd vaccination was reported commonly, but no fever was reported in children and adolescents aged 9 to 17 years.

During a clinical trial involving children aged 6 to 35 months, the following reactions were very common: sleep disturbance, loss of appetite, crying, irritability and sleepiness.

  • Celvapan (H1N1)v side effects observed during the pandemic flu vaccination program

The side effects listed below have occurred with Celvapan (H1N1)v in adults and children during the pandemic flu vaccination program.
