[Market vaccinations in Rotterdam].

The COVID-19 vaccination rate is not evenly distributed across the Netherlands. In some neighborhoods, the vaccination rate is relatively low, causing individual health risks and a burden to the health care system. An explanation is the use of a national, general information campaign, while using a similar approach (equality approach) does not always lead to similar results. Therefore, we advocate the use of an equity approach instead, as defined by the WHO, which aims at achieving equal results by taking the specific needs of certain vulnerable groups into account. As an example, we describe an intervention that took place in Rotterdam, in which medical doctors, among which GPs, took the initiative to offer information about vaccinations and vaccination on the popular weekly markets of Rotterdam. Using interviews with medical volunteers who contributed to these market vaccinations, we outline the preconditions for successfully implementing such an outreach-based approach, and we make a number of practical recommendations.
