It was simply to encourage the inoculation of children by, not only making it a social event -- I think good use of behavioral economics in that, if you turn up with several other mothers to have your child inoculated, your sense of confidence is much greater than if you turn up alone.
Det handlede om at opfordre til vaccination af børn ikke bare ved at gøre det til et socialt arrangement - jeg synes det er fornuftig brug af adfærdsøkonomi, at hvis man møder frem med flere andre mødre for at få sit barn vaccineret, så er ens selvtillid meget større,  end hvis man møder frem alene.
