Covid vaccine

Hello All, I am new to this forum and would like to ask a question. Me and my husband are US citizens, are residents in Seville  and insured through Sanitas. I would like to find out what are our chances to get a vaccine and when. I asked Sanitas and they replied that "the vaccinations are not available through Sanitas, if they become available in our hospitals privately we will advise". Does anyone know if we need to do anything to be enrolled for the vaccination? Or just wait see what happens? Thanks.

Thanks!
