Article Synopsis
- A study by the Dutch municipal health service Utrecht examined the effects of mass testing (MT) for COVID-19 in the town of Bunschoten over six weeks in early 2021.
- The results showed that MT significantly increased both the number of tests conducted and detected infections, particularly among older residents, while the rest of the province saw stable numbers.
- While MT identified more asymptomatic and pre-symptomatic cases and reduced the time between symptom onset and testing, questions remain about its overall effectiveness and proportionality for broader community health strategies.
Vaccine hesitancy (VH) is considered a top-10 global health threat. The concept of VH has been described and applied inconsistently. This systematic review aims to clarify VH by analysing how it is operationalized.

This study aims to identify social-psychological factors associated with MPV acceptance among Dutch women to add to the current understanding of vaccine hesitancy worldwide, and to inform the development of communication and information campaigns about MPV.
Methods: We conducted a cross-sectional study using an online survey among 611 women (174 pregnant women, 205 women who had given birth in the past two years and 232 women of 20-35 years old).
Objective: To assess the intention to accept a pertussis cocooning vaccination and to examine the determinants that influence this intention among healthcare workers (HCWs) in maternity and paediatric care.
Design: Cross-sectional survey.
Setting: Maternity assistants, midwives, and paediatric nurses in the Netherlands.
Introduction: Pertussis cocooning is one of the strategies aiming to prevent the potential harm of pertussis in infants by vaccinating (among others) their parents. Several countries adopted this strategy, but uptake is a problem. Determinants of parental uptake are important in the design of an effective vaccination programme.

This puts infants (especially <6 months) at risk of severe complications, because they are too young to be fully protected by vaccination. The global pertussis initiative has proposed pertussis vaccination of young infants' close contacts, in order to reduce pertussis transmission and the burden of the disease on infants.
