Creo que es clarísimo. De todas maneras averigua con la embajada de Malta en España y nos cuentas que tal te va.....

The only instance in which a request for consideration for exemption from quarantine on medical grounds is where the first dose of vaccine caused immediate severe anaphylaxis requiring medical treatment. In all other medical conditions and situations, at least one of the authorised vaccines may be administered safely.

In the above exceptional circumstance only, on presentation of a valid, verifiable medical certificate which includes clear contact details of one’s medical specialist consultant, an exemption from quarantine on arrival from a red country/zone, may be requested by sending an email with all relevant documentation to covid19.health@gov.mt. Subject title of email should read as follows “EXEMPTION REQUEST: Name of person for whom the application is being requested.” If exemption is granted they must be in possession of a negative result for a nasopharyngeal Reverse Transcription Polymerase Chain Reaction (RT-PCR) COVID-19 test, performed no longer that 72 hours before arrival into Malta. Rapid Tests (Antigen Tests) are not accepted. A copy of the exemption letter from the Superintendent of Public Health must also be presented on arrival.

Vamos que has tenido que tener una reacción dd anafilaxia grave para que no te pusieran la 2 dosis y te tiene que hacer un informe detallado el médico, y eso enviarlo a ese mail y que te confirmen por escrito la excepción

Te diría que te fueses a un centro de vacunación masiva, pero justo hoy los han cerrado(porque se que estaban poniendo 2 dosis). O ir al centro de salud(esto lo veo más difícil)
Si no es así, te van a obligar a la cuarentena
