RESUMO
Tuberculosis (TB) still occurs frequently in the Netherlands among immigrants from countries where the disease is highly endemic, despite the mandatory TB screening upon settling in the Netherlands. The TB-ENDPoint study shows that immigrants from populations at risk for TB are prepared to be screened for latent TB infection (LTBI) and to complete preventative treatment. Cost-effectiveness analysis will have to determine whether and in which target groups screening can replace the present X-ray screening for TB. A targeted approach, in which LTBI screening is combined with screening for other infectious diseases such as hepatitis B and C and HIV, could favourably influence cost-effectiveness. Further research into implementation, involving all stakeholders, would be useful to optimize combined screening.

The immunity to vaccine-preventable diseases included in the Dutch immunisation programme in the general population and among orthodox reformed individuals who refuse vaccination was assessed. The programme induces good protection. However, a large proportion of adults lacks diphtheria and tetanus immunity. Measles, mumps and rubella seroprevalence was somewhat lower among vaccinated compared to unvaccinated cohorts. The prevalence of HibPS antibodies declined during 2.5 years after the fourth vaccination. However, protection occurs also by memory immunity. Herd immunity is sufficient among the general population, but not among orthodox reformed individuals. Immunosurveillance is an efficient way to evaluate the effects of immunisation programmes and identify risk groups for infection.
