Immunisation: MMR (18 months)

Indicator

IND215: The percentage of babies who reached 8 months old in the preceding 12 months, who have received at least 3 doses of a diphtheria, tetanus and pertussis containing vaccine before the age of 8 months.

IND216: The percentage of children who reached 18 months old in the preceding 12 months, who have received at least 1 dose of MMR between the ages of 12 and 18 months.

IND217: The percentage of children who reached 5 years old in the preceding 12 months, who have received a reinforcing dose of DTaP/IPV and at least 2 doses of MMR between the ages of 1 and 5 years.

IND218: The percentage of children who reached 5 years old in the preceding 12 months, who have received 1 dose of MMR between the ages of 1 and 5 years.

Resource impact

It is estimated that 269 million appointments in general practice were attended in England between 01 January 2019 and 31 December 2019 (see NHS Digital Appointments in General Practice), equivalent to around 920 per week for a GP practice assuming a list size of 10,000 people. There are around 56.0 million people in England (Office for National Statistics, 2018).

The latest data available (see Office for National Statistics 2019 dataset) indicate that there were around 611,000 live births in England in 2019. On average, around 90.6% (see NHS Digital 2018/19 Childhood Vaccination Coverage Statistics) are vaccinated for the range of vaccinations in the proposed indicators. 

Three theoretical increases in vaccination rate are modelled, 1%, 2% and 3%. It is estimated that none of these increases would lead to a significant increase in activity.  

It is estimated that there may be around an extra 4, 8 or 12 children requiring vaccination per GP practice per year. In a Sustainability Transformation Partnership (STP) area this is around an extra 200, 395 or 595 children requiring vaccination per year. 

Table 1 Estimated annual resource impact of more vaccinations for a theoretical 1%, 2% and 3% increase in the eligible population

-	Current activity	1% increase	2% increase	3% increase
Per GP practice (10,000 people)	395	4	8	12
Per STP (500,000 people0	19,770	200	395	595

This assumes a GP practice is 10,000 people and an STP is 500,000 people. The resource impact will be reduced where more than one vaccination is administered at the same time.
