Longer Wait for Sinovac Booster Improves Protection, Study Finds

A longer gap between second and third doses of China’s Sinovac Covid-19 vaccine provides more protection against the virus than a shorter wait, according to a study published in medical journal the Lancet.

Antibody levels in people who received a third dose eight months after their second dose rose more than twice as much as people who got a booster shot within two months of their second dose, according to researchers from Sinovac Biotech Ltd., Fudan University and several regional Centers for Disease Control and Prevention.
