By Dady Chery, Haiti Chery. A medical trial in Haiti — presumably of the oral cholera vaccine Shanchol — on poor women and children is being presented as a vaccination campaign. To avoid possible abuse it is essential that the Declaration of Helsinki guidelines be followed. The medical trial should be monitored by a panel of impartial observers; potential medical subjects should be advised of their rights, including the fact that they are entitled to informed consent, health monitoring, and participation that is voluntary, without coercion and with the option to withdraw at any time. UPDATES: April 12, Additional information about involvement of Harvard scientists in promoting oral vaccines for Haiti. April 17, Information on Shanta’s manufacture of the pentavalent vaccine Shan5 recommended for recall and destruction by the World Health Organization.
