As of September 2018, Dong Junhua, the parent of a child affected by substandard vaccines from Dancheng county in the central province of Henan, is being held under criminal detention on suspicion of "picking quarrels and stirring up trouble". Meanwhile, Shanghai-based vaccine campaigner Tan Hua "disappeared" in Beijing on Sept 3 after going to the capital to campaign for compensation for disability, which she says is linked to a rabies vaccine several years ago. Police also detained campaigner Hu Changjie for nine days under administrative detention for "disrupting public order," while Jiang Peng of Henan's Hebi city was held for six days on the same charge, and Zou Wanli from Guangshan county was held for 10 days' administrative detention, CHRD (Chinese Human Rights Defenders) said. "Protesters against government mishandling of scandals over faulty vaccines faced a swift police response after trying to demonstrate on Tiananmen Square. The protesters were victims of faulty vaccinations, which were believed to have caused permanent health damage, as well as their parents and supporters," CHRD said.
