The developer HIPRA is looking for volunteers to participate in a 4th dose study of the COVID-19 vaccine it is developing. Adults who have received 3 doses of Comirnaty (Pfizer) against COVID-19 (the last dose administered between the last 6 and 12 months), who have not passed COVID-19 and who are not pregnant are eligible to participate.

You have time to participate until 5th October at 24h.

Volunteers will receive a booster dose of the new vaccine under investigation and will be followed up to know the safety and response (immunity) of a 4th dose of HIPRA.
