Almost 32% of the population of the Netherlands belonged to the NPG target group in 2009. Before the target group was widened to include healthy persons of 60 to 64 years of age in 2008, it was about a quarter of the country's population.

Immunization coverage

Immunization coverage has risen from 42% in 1995 to 70-75% in recent years. This means that about 22% of the total population has been vaccinated every year since 2008. Before that year and the expansion of the target group, this figure had been about 18%. In 2009 immunization cover was 70.4% (71.5% in 2008) for all risks groups combined and 76% for those aged 60 and over. For those aged 60 and over with medical grounds, immunization cover was 83% in 2009; for those without medical grounds this was 64%. In the new target group (those aged 60-64 years with no medical grounds), immunization cover was almost 55% in 2009 (52% in 2008).

In 2009 3.7 million vaccinations were administered, mostly by general practitioners. The Netherlands has over 8400 GPs in about 5000 practices. Up to 2007, a 'standard practice' of 2350 patients had an average of about 600 indicated clients, of whom on average 425 were vaccinated. From 2008 onwards, on average 28 healthy clients aged 60 or over have been added to these figures.

The NPG programme has been shown to be cost-effective (defined as ‘costing less than €20,000 per saved life year’), including after its target group was widened to include healthy people aged 60 to 64.
