CanSino stressed that all vaccines against the new coronavirus are still in development and therefore, there is no certainty about how long their effectiveness lasts.
“We do have the certainty that at some point each and every one will have to be reinforced“He said in a statement.
The company added that it is not yet known how much this reinforcement will be applied, but the date will be informed “as soon as we have the necessary data.”
He also added that people vaccinated with the dose of CanSino, which in the case of Mexico includes all educational personnel, are protected against developing a serious version of the disease, as well as hospitalizations and death.
