Childhood immunisation uptake rates, quarter and year ending 31 March 2009.

INTRODUCTION

Children in Scotland are protected through immunisation against many serious infectious diseases. Vaccination programmes aim both to protect the individual and to prevent the spread of these illnesses within the population. As a public health measure, immunisations have been hugely effective in reducing the burden of disease. It is of public health concern when immunisation rates fall, as this increases the possibility of disease transmission, and hence complications arising from outbreaks of infectious diseases.
 
In Scotland the target of the national immunisation programme is for 95% of children to complete courses of the following childhood immunisations by 24 months of age:  diphtheria, tetanus, pertussis (whooping cough), polio, haemophilus influenzae type b (hib) and meningococcal group C (MenC).  An additional national target of 95% uptake of one dose of MMR vaccine by 5 years of age (with a supplementary measure at 24 months) was introduced in 2006 to focus efforts on reducing the number of susceptible children entering primary school.
 
There have been a number of changes to the childhood immunisation programme for children around 0-5 years of age since September 2006:
  • a new Pneumococcal Conjugate Vaccine (PCV) immunisation was introduced
  • a change was made to the schedule given in the first 4 months of life
  • there was the addition of an appointment at around 12 months to deliver the Hib/Men C booster
  • a pneumococcal catch up campaign commenced
  • in September 2007 a Hib vaccination catch up programme was introduced 
  • an initiative to reduce the age at which pre-school immunisation is routinely offered, to around 3.5 years of age.
The consequences of these changes are that each child needs more appointments, and this may lead to some older children receiving their immunisations slightly later than scheduled due to prioritisation of younger children for primary immunisation appointments.  This may have reduced the reported uptake rates for some vaccines by 5 years of age during the first half of 2008 though rates are now around previous levels.  Uptake rates by 6 years of age have remained high throughout.
 
Childhood immunisation uptake rates for Scotland are monitored and published quarterly.  This release includes data to 31 March 2009.

KEY POINTS

  • In Scotland as a whole, quarterly uptake rates by 24 months of age for primary courses of diphtheria, tetanus, pertussis, polio, Hib, MenC and PCV remain high and stable at around 96% to 98%.
  • Quarterly uptake of one dose of MMR by 24 months increased slightly to 92.9%.  Quarterly uptake by 5 years of age remains at 95.6% and exceeds the 95% target.
  • Quarterly uptake of the Hib/MenC booster vaccination by 24 months rose to 93.7% this quarter (92.0% in previous quarter).  Quarterly uptake of the PCV booster by 24 months rose to 93.8% (in the previous quarter uptake was 93.3%).  These vaccines were introduced to the childhood immunisation schedule in September 2006 along with the other substantial changes to the programme mentioned above.

INTERPRETATION

In Scotland uptake rates for the childhood booster vaccines (diphtheria, tetanus, pertussis and polio, and the second dose of MMR (MMR2)), have historically been reported by 6 years of age.  In line with figures for the rest of the UK, from quarter ending December 2006, uptake rates for these vaccines are now reported by 5 years of age.  For trend purposes, reporting by 6 years of age will also continue to be presented.
 
NHS Orkney have identified data recording issues which may be affecting their reported uptake rates.  These issues are currently being reviewed by NHS Orkney.

DETAILED FINDINGS

For the quarter ending 31 March 2009, at Scotland level:
 
Uptake rates by 12 months of age
  • Uptake rates by 12 months of age for primary courses of diphtheria, tetanus, pertussis, polio, Hib, MenC and PCV remain above 95%. 
Uptake rates by 24 months of age
  • Uptake rates by 24 months of age for primary courses of diphtheria, tetanus, pertussis, polio, Hib, MenC and PCV remain high and stable at around 96% to 98%.
  • The combined Hib/MenC booster (normally given at around 12 months of age) was introduced in September 2006.  This required the inclusion of an additional immunisation appointment in the childhood schedule.  Uptake of this vaccine by 24 months of age has risen each quarter to reach 93.7% for the latest quarter (the previous quarterly figure was 92.0%). 
  • A booster dose of PCV was also introduced in September 2006 (normally given at the same appointment as the first dose of MMR at around 13 months of age).  Uptake for this vaccine by 24 months of age is 93.8%.  This is an increase of 0.5 percentage points on the previous quarter when the rate was 93.3%.
  • Uptake of one dose of MMR (MMR1) by 24 months is 92.9% (the previous quarterly figure was 92.6%).  MMR1 uptake rates by 24 months have continued to be above 90% since autumn 2005.
  • Uptake rates by 5 years of age
  • Uptake of one dose of MMR (MMR1) by 5 years of age is 95.6% (the same as the previous quarterly figure).  This once again exceeds the 95% target.  By 24 months the reported uptake for this cohort of children was 90.9% showing that a significant number of children are immunised beyond the standard age.
  • Uptake of the second dose of MMR (MMR2) by 5 years old is 87.2%.  This is a decrease of 1.4 percentage points from the previous quarter when the rate was 88.6%.  Other pre-school booster vaccines experienced a similar fall (from 91.5% to 89.6%).
This release also provides an update to annual immunisation uptake rates to show data for the year ending 31 March 2009.
