How the Sinovac vaccine works

The Sinovac vaccine contains an inactivated form of coronavirus that cannot cause the disease. It also has a substance that helps strengthen the immune response to the vaccine.

When given the shot, the immune system identifies the inactivated virus as foreign and makes antibodies against it, which will then recognise the active virus and defend the body against it.

Few people aged over 60 took part in the clinical trial of Sinovac’s jab. However, the World Health Organization said there should be no upper age limit on the vaccine as there is “no reason to believe it has a different safety profile” in older generations.

The Sinovac jab is already in use in 22 territories around the world, according to the AFP.

Apart from China, the countries using Sinovac include Chile, Brazil, Indonesia, Mexico, Thailand and Turkey.

China’s ambassador in Geneva, said Sinovac’s Emergency Use Listing status expanded the number of global tools to fight the pandemic.
