Gilenya and covid vaccine

Hi Everyone! Just wondering if anyone who is on Gilenya has had their Covid vaccine yet (either Pfizer or AZ) and what sort of side effects they have experienced. My husband is due to take his vaccine on Friday but I am very worried since he has limited mobility anyway and we do not want a permanent worsening of his condition. He is 59 years old and has SPMS with relapses. He has been on Gilenya for many years and it has helped him with this MS progression immensely and so does not want to stop taking this medication. Thanks!
