The lock-down imposed in many countries to fight the ongoing COVID-19 pandemics is impacting the development of research projects worldwide. Many MSCA fellows have been impacted and some have been voicing that the flexibility measures put in place to alleviate negative impacts are not sufficient in all cases. The present survey launched by the MCAA aims at collecting information on how the situation is impacting current MSCA fellows (all actions) and on where the available solutions to ease the impact on their projects is insufficient. This survey is for information purpose only. There is no guarantee that particular cases will be solved. By filling out the survey, you are authorizing to treat your data for internal purposes in aggregate form.
