The newspaper recalls that it was a mixture of two different vaccines that affected millions of doses, but the pharmaceutical company assured that the batches supplied to Mexico were verified under the required standards.

The AstraZeneca vaccines that Mexico received were manufactured under contract in a plant of the Emergent BioSolutions company in Baltimore, Maryland, which is now under investigation by the Food and Drug Administration (FDA), the federal agency in charge of regulating the sector.

AstraZeneca confirmed that those batches used in Mexico and Canada were manufactured at that plant.

In a press release, a spokesperson informed that in March the US government ordered it to export again those batches to both countries.

We can confirm that those batches manufactured at Emergent’s plant met the rigorous requirements they were compelled to follow. Safety tests and required quality control measures were carried out at every step of the production process, he assured.

He explained that all checks were performed before releasing the packages and quality information from the plants involved were properly submitted to the regulatory agencies in each country.
