The Chinese vaccine CanSino has been approved by the Secretariat of Health in Mexico for emergency use, however, its efficacy of up to 5% minimum is quite questionable, when other vaccines have an effectiveness of 75%, providing greater assurance to people that they are getting an antidote that will protect them against COVID-19.
Last February 10, the Undersecretary of Health, Hugo López-Gatell published in his social networks a slide showing the list of vaccines, their origin and the percentage of general effectiveness, showing that CanSino has from 5% effectiveness up to 74%.
In the process, several irregularities during the clinical trials have been denounced by patients, such as the fact that the authorities had not analyzed all the data from 15 thousand volunteers from different states of Mexico and that instead tests from people in Pakistan were used.
The CanSino vaccine does not have available data related to cases of severe disease, nor does it disclose how it performs against the various Brazilian, British and South African vaccines, when other vaccines approved in Mexico do have these statistics.
It is worth mentioning that there has been much secrecy from Mexican government entities regarding the evaluation process of the vaccine, despite the fact that there was an agreement to inform patients about the progress.
In May 2021 alone, more than 50 thousand people were vaccinated in Queretaro with the CanSino antidote, which, let's remember, has a confidence limit of less than 5%, well below the World Health Organization's (WHO) requirement of 30%.
