Hi everyone. We are due to go to Spain in July. My son has only had 1 vaccine and was due to have his next one this weekend, but has just tested positive for Covid! This means that he wont be able to get his 2nd vaccine before we fly. I know that we can get a "recovery certificate" for him which enables him to fly if he has recovered from covid, but I have no idea what tests he needs to have or how I get the certificate. Any advice would be appreciated. Thanks
