Vaccine hesitancy has become an increasing problem in Europe, which is directly reflected in the number of infectious disease cases. For example, more than 41 000 measles cases have been counted in the first half of 2018, which is far more than the total number of cases in any year of this decade [1]. A recent study shows that vaccine safety and effectiveness is perceived differently in European countries, and that these perceptions influence vaccine uptake [2].

But what does the term vaccine hesitancy mean and how is this behaviour distributed in society?

Vaccine hesitancy, as defined by the WHO SAGE Working Group, is a behavioural phenomenon, which “refers to delay in acceptance or refusal of vaccination despite availability of vaccination services” [3]. The term is used to illuminate the complexities present in the vaccine decision-making process, with hesitancy being context dependent and varying across time and place. Convenience, confidence and complacency are main influencing factors on vaccine hesitancy [3].

For one group, this decision-making process seems to be a particular burden – pregnant women.

Concerns that influence vaccine uptake during pregnancy may differ from those that affect routine vaccination. During pregnancy, women might be more cautions and feel responsible for the life of the foetus [4]. Studies show, that pregnant women tend to highly overestimate the teratogenic risk of medication [5]. They therefore have high information needs [6] and it is important for health care professionals to be aware of this.

In addition to the increased risk perception, various social norms exist during the time of pregnancy in different cultures which influence the decision-making of pregnant women [4]. Many women, who are in favour of routine vaccination, show concerns about immunisation during pregnancy.

Vaccinations during pregnancy, for example with the influenza or pertussis vaccine, are proven to be safe and effective. They can prevent serious complications for mother and child. For health care professionals it is therefore important to be aware of the concerns of pregnant women and provide the information they are seeking for. A vaccine-hesitant mother is not an anti-vaccer per se, but a woman in a difficult situation where she makes decisions for two and feels social pressure. This shows how complex the discussion around the anti-vaccer movement actually is. People who refuse or delay vaccines are part of a heterogenous group and there is no one-fits-all solution.

Only respectful communication strategies and evidence-based information can help us to overcome these problems and increase the numbers of vaccination. All health care professionals play a role in this and should take them seriously.
