4in1 and MMR

If 1000 people get diphtheria

• 50 will die

The bacteria release a toxin (poison) which can lead to paralysis and heart failure.

If 1000 people get vaccinated

• 100 will have discomfort, redness and swelling where the injection was given or have a fever.

If 1000 people get polio:

• up to 10 will become paralysed

Of these 10 people with paralysis:

• 5 will be permanently paralysed; and
• 1 may die.

If 1000 people are immunised:

• 100 will have discomfort redness and swelling where the injection was given or will have a fever

If 1000 people get tetanus:

• 100 will die

The risk is greatest for the very young or old.

If 1000 people are immunised:

• 100 will have discomfort, redness and swelling where the injection was given or will have a fever.

If 1,000 people get whooping cough:

• 2 will die from pneumonia or brain damage (almost all deaths are in children under the age of 6 months)
• 10 will have fits (15 if under 6 months old)
• 1 will get encephalitis (2 if under 6 months old);
• 50 will get pneumonia (100 if under 6 months old)
• 200 will need to go into hospital

If 1000 people are immunised:

• 100 will have discomfort, redness and swelling where the injection was given or will have a fever

4 in 10,000 will cry for more than three hours after immunisation; and

1 in 10,000 will have a convulsion (fit).

If 1000 people get measles

• 1 or 2 will die
• 50 will get an ear infection
• 40 will get pneumonia or bronchitis
• 5 will have convulsions (fits)
• 160 will get diarrhoea
• 1 will develop encephalitis (swelling of the brain) For every 10 children who develop encephalitis - 1 will die and - up to 4 will have brain damage.

1 in 8000 children under two years of age get SSPE (brain degeneration), which may be many years after measles and is always fatal.

1 in 6000 will get a blood clotting problem.

If 1000 people are immunised:

• 100 will have discomfort, redness and swelling where the injection was given or will have a fever.
• 50 will get a rash six to ten days later (this is not contagious)
• 1 will have a febrile convulsion (fit)

1 in 10 million may develop encephalitis (inflammation of the brain)

1 in 22,000 will get a temporary blood clotting problem.

Reactions are much less common after the second MMR vaccine.

If 1000 people get mumps:

• 50 will get viral meningitis
• 1 will get encephalitis (brain inflammation)
• 400 men who have mumps will get swollen testicles
• 300 will get fever, a headache, and swollen salivary glands under the jaw, and

1 in 20000 may become deaf.

Mumps can also rarely cause infertility in men.

If 1000 people are immunised:

• 100 will have discomfort, redness and swelling where the injection was given or will have a fever
• 10 may develop swelling of the salivary glands under the jaw (this is not contagious)
• 1 in 10 million may develop encephalitis (inflammation of the brain).
• Reactions are much less common after the second MMR vaccine.

If 1000 mothers develop rubella in early pregnancy:

• 900 babies will have a major birth defect (such as deafness, blindness, brain damage or heart defects) if the mother got rubella in early pregnancy.

If people get rubella:

1 in 3000 get thrombocytopenia (bruising or bleeding of the skin)

1 in 6000 get encephalitis (inflammation of the brain)

1 in 2 will get a rash and painful swollen glands; and

More than half of women with rubella get painful joints.

If 1000 people are immunised:

• 100 will have discomfort, redness and swelling where the injection was given or will have a fever
• 50 get swollen glands, a stiff neck, or joint pains
• 50 get a rash (which is not contagious)
• 1 in 25,000 get bruising or bleeding; and
• 1 in 10 million may develop encephalitis (inflammation of the brain).
• Reactions are much less common after the second MMR vaccine.
