Mexico Grants Emergency Approval to AstraZeneca-Oxford Coronavirus Vaccine VOA News Mexico has become the latest nation to approve the COVID-19 vaccine jointly developed by British-Swedish pharmaceutical giant AstraZeneca and Oxford University. Foreign minister Marcelo Ebrard announced the "very good news" that the government had granted emergency approval for the vaccine Monday on Twitter, adding that "production will start very soon in Mexico." The AstraZeneca vaccine joins the Pfizer-BioNTech vaccine as the only ones so far approved by Mexico City. Late-stage clinical trials of the AstraZeneca-Oxford vaccine revealed it to be 70% effective against COVID-19. The vaccine had a 62% efficacy rate for participants given a full two doses, but separate tests revealed it to be 90% effective when given a half-dose followed by a full dose weeks later. Unlike the Pfizer-BioNTech vaccine, which needs to be stored in super-cold refrigerators at temperatures below 70 degrees Celsius, the newly approved vaccine can be stored at normal temperatures of 2 to 8 degrees Celsius, making it easier to transport and administer to people in poorer and remote nations. .
