For an applicant who got both an MD (with a doctoral equivalence) and a PhD, the eligibility will be based on the earliest degree that makes the applicable eligible (either PhD or doctoral equivalence award).
As an example, if the doctoral equivalence took place :
1) after the PhD award, the PhD date will be then taken into consideration for eligibility (ie. 2-7 years past PhD award date for starters and 7-12 past PhD award date for consolidators).
2) before the PhD award, the calculation for eligibility will be based on the MD award date (ie. 4-9 years past MD award date for starters and 9-14 past MD award date for consolidators)
For a researcher (with PhD equivalence) applying on the basis of his/her MD degree, please note that for clinical specialty training, only the time spent after the PhD award (ie MD +2 years) will be considered for the extension of the eligibility window (the maximum duration granted for eligible career breaks cannot surpass 4 years and 6 months).
As indicated I the ERC Work Programme 2014, an MD is not an eligible degree in itself. A doctoral equivalence is required on top of it. Therefore, in the case described below and in the absence of doctoral degree equivalence before the PhD award, the calculation for eligibility will be based on the PhD award date.
