NeisVac-C is a vaccine to prevent invasive meningococcal disease caused byNeisseria meningitidisgroup C. This is a type of bacteria that can cause severe infections, which sometimes produce potentially fatal symptoms/reactions such as meningitis and septicemia (blood infection).

NeisVac-C is administered to children from 2months of age, adolescents, and adults. The vaccine works by stimulating your body to produce its own protection (antibodies) against group C bacteria.

This vaccine will only protect you against the disease caused by the bacteriaNeisseria meningitidisgroup C. It will not protect you against other groups ofNeisseria meningitidisor other organisms that cause meningitis and blood infection.As with other vaccines, NeisVac-C may not completely prevent meningococcal infections of group C in all vaccinated individuals.

No useNeisVac-C

• If you have ever had an allergic reaction to any previous dose of this vaccine or to any of its components, including tetanus toxoid (listed in section 6). The symptoms of an allergic reaction include skin rash, facial and throat inflammation, difficulty breathing, blue discoloration of the tongue or lips, decreased blood pressure, and collapse

• If you have ever had an allergic reaction to any other vaccine indicated for preventing meningococcal infections of group C.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before receiving the NeisVac-C vaccine if the person receiving the vaccine (for example, you or your child):

• has hemophilia, is taking an anticoagulant, or has any other condition that prevents proper blood clotting;
• has an acute illness with fever. In this case, your doctor or nurse may advise delaying vaccination until you are feeling better.
• has an autoimmune disease or a weakened immune system for any reason. The vaccine can still be administered, but it may provide a lower level of protection against Neisseria meningitidis group C.For example:
• • if you do not produce antibodies very efficiently;
  • if you are taking medications that reduce your immunity to infections (such as anticancer medications or high doses of corticosteroids);
  • if you do not have a spleen or have been told that your spleen does not function correctly;
• was born very prematurely (at 28 weeks of gestation or earlier). There may be longer than usual intervals between breaths for 2-3 days after vaccination and this may require follow-up;
• is over 65 years old.

This vaccine cannot cause meningococcal disease of group C. If you or your child experience any of the following symptoms of a meningococcal infection, for example:

• neck pain
• stiff neck
• intolerance to light (photophobia)
• drowsiness
• confusion
• spots similar to red or purple rash that do not disappear when pressed

you must contact your doctor, nurse, or go to the Emergency Service immediately.

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

Other medicines and NeisVac-C

Inform your doctor, pharmacist, or nurse if you or your child isusing orhas recentlyusedany other medicine, including those obtained without a prescription or if you have recently received another vaccine.

Your doctor or nurse will inform you if it is necessary to administer NeisVac-C at the same time as other injectable vaccines.

NeisVac-C can be administered at the same time, but as separate injections in different injection sites, as the vaccines for:

• polio
• measles, mumps, and rubella (MMR)
• diphtheria, tetanus, and pertussis (whooping cough)
• Haemophilus influenzaetype b (Hib)
• Streptococcus pneumoniae(pneumococcus)

NeisVac-C can be administered to children at the same time as certain types of vaccines that protect against hepatitis B. Your doctor, pharmacist, or nurse will inform you if this is necessary and the most suitable vaccine.

NeisVac-C can be administered at the same time as oral vaccines that protect against infections caused by rotavirus.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or intend to become pregnant, consult your doctor, pharmacist, or nurse before using this vaccine.

However, NeisVac-C can be administered by your doctor, pharmacist, or nurse if the risk of infection is high.

Driving and operating machinery

No studies have been conducted on the effects of NeisVac-C on the ability to drive and operate machinery.

However, some of the effects listed in section4 “Possible adverse effects” may temporarily affect you. If this occurs, wait until the effects have disappeared before driving or operating machinery.

A dose of NeisVac-C contains 0.5 ml (a very small amount of liquid).

NeisVac-C is injected into the muscle. It is normally injected in the thigh in children under one year and in the arm in children over one year, adolescents, and adults.

Children between 2 and 4 months of age

Your child will be given two doses of NeisVac-C, at least two months apart.

Children from 4 months of age onwards, adolescents, and adults

They will be given one dose.

Children between 2 and 12 months

A booster dose should be administered approximately at 12 – 13 months of age, at least six months after the last vaccination with NeisVac-C in the primary vaccination schedule.

If you (or your child) have been given more NeisVac-C than recommended

There is no experience with overdoses of NeisVac-C.However, an overdose is highly unlikely given that it is administered via a single-dose syringe by a doctor or nurse.

If you forgot a dose of NeisVac-C or interrupted the vaccination schedule

Your doctor or nurse will inform you of the vaccination schedule to follow. If you or your child forgets one of the recommended doses or interrupts the recommended vaccination schedule, incomplete protection may be achieved.

If you have any other questions about the use of this vaccine, ask your doctor, pharmacist, or nurse.

Like all vaccines, NeisVac-C can cause side effects, although not everyone will experience them.

As with all injectable vaccines, allergic reactions may occur. Although they are very rare, they can be severe. For this reason, it is always necessary to monitor and have appropriate medical treatment available for a certain period of time after vaccination.

The signs and symptoms of severe allergic reactions include:

• Swelling of the lips, mouth, and throat that can cause difficulty swallowing or breathing
• Skin rash and swelling of the hands, feet, and ankles
• Loss of consciousness due to a drop in blood pressure.

These signs or symptoms usually occur immediately after injection, when the person is still in the clinic or doctor's office. Consult your doctor or nurse immediately if any of these symptoms occur once you have left the consultation or clinic.

Composition of NeisVac-C

The active principle in a dose of the vaccine (0.5 milliliters) is 10 micrograms of de-O-acetylated polysaccharide (from Neisseria meningitidisgroup C (strain 11)). This is combined with 10 to 20 micrograms of a protein called tetanus toxoid, adsorbed on hydrated aluminum hydroxide (0.5 milligrams of Al3+).

The other components are sodium chloride (cooking salt), water for injection preparations, and hydrated aluminum hydroxide. Hydrated aluminum hydroxide is included in this vaccine as an adsorbent to improve and/or prolong the protective effect of the vaccine.

NeisVac-C is a white or off-white semi-opaque injectable suspension that is supplied in a pre-filled syringe.
