In this screen you can select the vector used in the activity. If the vector has a pathogenicity class defined, it is automatically adopted. When the vector is empty or 0, you can still change this pathogenity class. Furthermore, you can indicate whether the vector is on the list A2 of appendix 2. If this is not the facade, you must also add a so-called vector chart containing all functional components to the application. For vectors that do not meet the criteria in article 5.2 ofappendix 5 the deviating parts should be included in the remarks field. If the vector chart is present, tick the 'Vector chart present' field.
