The activities described in this lot should be performed in collaboration with the national competent  public authority of the concerned EU Member States; the ECDC will facilitate these interactions if  needed. All tasks are expected to be performed at the contractor’s premises and on the study sites. It is estimated that  only two meetings (see table with deliverables) could be held either at ECDC or in a location in EU/EEA.  See the Table Lot 2 / Technical annex B summarising the type of tasks and the related deliverables  envisaged under the lot during the duration of the framework contract including estimated timelines and  quality requirements. 2.3.2 Place of performance and number of meetings of LOT 2  2.3.3 Summary table of tasks, deliverables, quality requirements and timelines in LOT 2  2.4 Description of the services LOT 3: COVID-19 vaccine-related studies in  long-term care facilities 2.4.1 Scope of the services in LOT 3  2.4.2 Place of performance and number of meetings of LOT 3  2.4.3 Summary table of tasks, deliverables, quality requirements and timelines in LOT 3  The aim of this lot is to conduct COVID-19 vaccine effectiveness studies in long-term care facilities in  EU/EEA countries. The vaccine effectiveness studies will build on previous initiatives and protocols of ECDC  and can be developed from prospective and retrospective data collection, as agreed with ECDC and as  relevant in connection with the study objectives. Sources of data external to those retained at the long- term care facility-level could be used if needed to assess primary or secondary outcomes, as agreed with  ECDC. Additional studies to assess the effect of vaccination in these settings (e.g. vaccination impact  studies, outbreak studies, transmission studies) may be requested. The contractor is expected to perform the activities in close collaboration with ECDC and taking into  account the work performed by ECDC projects related to long-term care facilities (LTCF) such as the  Healthcare-associated infections and antimicrobial use in long-term care facilities project 4, as well work  performed by other international stakeholders, such as the EMA and the European Commission.  The activities described in this lot should be performed in collaboration with the national competent  public authority of the concerned EU Member States; the ECDC will facilitate these interactions if  needed. All tasks are expected to be performed at the contractor’s premises and on the long term care facility/country  level. It is estimated that only two meetings (see table with deliverables) could be held either at ECDC or in a  location in EU/EEA  See the Table Lot 3 / Technical annex C summarising the type of tasks and the related deliverables  envisaged under the lot during the duration of the framework contract including estimated timelines and  quality requirements. 19
