Produced by Sinovac company, the CoronaVac contains SARS-CoV-2 antigen (600SU) as the active ingredient, aluminium hydroxide (0,45 mg/ml) as an adjuvant, sodium chloride as an isotonic agent (9mg/ml), disodium hydrogen phosphate (1,16 mg/ml) and monosodium hydrogen phosphate (0,2 mg/ml) as buffering agents, sodium hydroxide as a pH regulator, and water.
The CoronaVac vaccine contains the SARS-CoV-2 antigen; in other words, inactivated COVID-19 viruses, as the active ingredient. These viruses, which have lost their ability to cause disease, do not create an infection risk when given to the body, but help to produce antibodies and gain immunity.
The CoronaVac vaccine contains aluminum hydroxide as an auxiliary substance, and this substance helps to increase the body's response to the weakened viruses contained in the vaccine.
The salt in the vaccine, called sodium chloride, helps to adjust the vaccine density in accordance with the body fluids, while sodium hydroxide provides the necessary acid-base balance for the vaccine content to be stored for a long period of time.
Monosodium and disodium hydrogen sulphate are the substances used to prevent the vaccine from losing its antigenic feature.
Water is used to hold all these ingredients together.
