The sponsor HIPRA is looking for volunteers over the age of 18 who have received Pfizer-BioNTech's Comirnaty vaccine against COVID-19 at least 6 months ago to study an investigational new vaccine it is developing against COVID-19.

Volunteers will receive a booster dose of the new investigational vaccine or an already marketed vaccine and will be followed for up to one year for safety and response (immunity).
