The goal of this open-label clinical trial is to evaluate the safety and immunogenicity of INAVAC (Vaksin Merah Putih - UNAIR SARS-CoV-2 (Vero Cell Inactivated)) Vaccine as Homologue Booster in Adult Subjects in Indonesia. The main question it aims to answer is: "To evaluate the humoral immunogenicity profile at 28 days following vaccination with INAVAC vaccine as homolog booster administered intramuscularly in healthy adults age 18 years and above". Participants will be administered one dose of vaccination for the third dose (booster vaccination) intramuscularly.

This is an observer blind randomized controlled trial study to evaluate the humoral immunogenicity profile - neutralizing antibody - after 28 days following vaccination with Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) vaccine as heterologue booster compared with CoronaVac administered intramuscularly in healthy adults age 18 year and above.
Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) vaccine is an inactivated vaccine made of SARS-CoV-2 virus isolated from a patient in Surabaya, composed with aluminium hydroxy gel, tween 80, and L-histidine, and this will be the first booster study in human.

This study is a multicenter, randomized, double blind, controlled, phase III clinical trial (Immunobridging Study) to evaluate the immunogenicity and safety of Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) in healthy populations aged 18 years and above. Vaksin Merah Putih - UA SARS-CoV-2 (Vero Cell Inactivated) is an inactivated vaccine made of SARS-CoV-2 virus isolated from a patient in Surabaya, composed with aluminium hydroxy gel, tween 80, and L-histidine, and this study will be the first phase III in human.
