We have added the 'procedure' of MMR vaccination to the Conditions section of Keep Me Informed. This includes links to the NHS and Merck Manual resources on the subject.

The incidence of measles throughout the world is increasing to epidemic levels.

A significant factor in eliminating this worrying trend is to ensure that information is not just created, but disseminated to those who are concerned about vaccination.

The effect of disinformation needs to be countered, but it is clear that factual evidence of the safety of vaccinations is being overwhelmed by those who use cynical emotional tactics to trick people into disbelieving the medical realities.

Keep Me Informed will explore the many ways in which we can promote scientific evidence.

Vaccines work by making us produce antibodies to fight disease without actually infecting us with the disease.

If the vaccinated person then comes into contact with the disease itself, their immune system will recognise it and immediately produce the antibodies they need to fight it.

Newborn babies are already protected against several diseases, such as measles, mumps and rubella, because antibodies have passed to them from their mothers via the placenta.

This is called passive immunity. Passive immunity usually only lasts for a few weeks or months. In the case of measles, mumps and rubella, it may last up to 1 year, which is why the MMR jab is given to children just after their first birthday.

How a vaccination programme works
When a vaccination programme is introduced, everyone in the population of a certain age or risk group is offered a specific vaccine to try to reduce the number of cases of the disease.

Vaccination programmes aim to protect people for life. They often concentrate on young children, as they're particularly vulnerable to many potentially dangerous infections.

Some vaccination programmes are targeted at older people, as with the shingles vaccine, or certain risk groups, as with the hepatitis B vaccine.

When a vaccination programme against a disease begins, the number of people catching the disease goes down. As the threat decreases, it's important to keep vaccinating, otherwise the disease can start to spread again.

If enough people in a community are vaccinated, it's harder for a disease to pass between people who have not been vaccinated. This is called herd immunity.

Herd immunity is particularly important for protecting people who can't get vaccinated because they're too ill or because they're having treatment that damages their immune system.

Public Health England (PHE) records the vaccinations that adults and children receive. PHE also records the number of cases of each disease each year.

This way, PHE can work out the impact that each vaccination has on a particular disease. This data helps the Joint Committee on Vaccination and Immunisation (JCVI) consider whether the routine vaccination programme needs to be changed.
