We are holding an in-person conference here in Barcelona in April 2022.
Regarding COVID-19 restrictions, participants will not be required to present a vaccination certificate at the conference site, but wearing a face mask indoors is currently still required in Spain.
This requirement may be partially lifted around the time the conference will take place, but note that face masks will still be obligatory in some contexts (e.g., public transport).
We are waiting to hear about the university’s latest regulations.
