This is a multicentre Phase II trial evaluating different booster strategies in individuals already vaccinated against SARS-CoV-2. This trial allows testing of different booster strategies for comparative assessment of their immune responses and safety against SARS-CoV-2 and its variants. This study tests whether a 4th vaccination dose is needed and determines the optimal booster vaccination schedule for further evaluation in a phase III trial. : An International Multicentre, Phase 2, Randomised, Adaptive Protocol to determine the need for, optimal timing of and immunogenicity of administering a 4th homologous mRNA vaccination dose against SARS-CoV-2 in the general population (18+ years) already vaccinated against SARS-CoV-2 (EU-COVAT-2 BOOSTAVAC) - EU-COVAT-2 BOOSTAVAC
