Shouldn't be a problem. One thing though, I would wait for at least two weeks, sometimes three, after the second vaccination dose to roll. This is because MDMA has been proven to have a profound dampening effect on the immune system and rolling while the vaccine-induced antibodies are still building up might hamper the development of said antibodies
In case of the Pfizer vaccine I would wait for two weeks after the second dose at least (maximum immunity takes about a week to build up, after the second dose), for three weeks in case of Moderna (maximum immunity takes about two weeks to build up after the second dose) and for three weeks after the single Johnson dose (maximum immunity takes about two weeks to build up after the single dose). This is with a generous safety margin of one additional week so you could roll one week earlier and that shouldn't be a problem either
