COVID-19 vaccination: this is how the world calendar advances | Digital Trends Spanish
The race to develop the vaccine for COVID-19 is already bearing its first fruits. With 2020 marked by pandemic and lockdowns, and with multiple antidotes in development, 2021 promises to be a more auspicious year.
Four are the antidotes that have shown the most promising results, with efficacy exceeding what is required by agencies such as the US Food and Drug Administration (FDA) to authorize vaccines.
According to the laboratories themselves, this is the effectiveness of the vaccines against COVID-19, according to the final results of their phase 3 studies:
With these data, the laboratories have already started applications for authorizations to regulatory bodies and thus start the vaccination process. Next, we detail in which stage the main territories are.
The United States began the vaccination process on December 14, 2020, after the antidote developed by Pfizer and BioNTech received authorization for emergency use for those over 16 years of age.
Meanwhile, on December 21, 2020, the process began with the Moderna vaccine for those over 16 years of age.
For now, these are the approved vaccines:
- Pfizer-BioNTech: emergency vaccination from December 14.
- Modern: emergency vaccination from December 21.
The European Medicines Agency (EMA) approved the Pfizer and BioNTech vaccine on December 21, 2020, a week earlier than originally projected. In this way, vaccination could begin before the end of 2020.
The block has signed contracts with six laboratories to buy 2 billion doses. The suppliers will be the French Sanofi, the British GSK and AstraZeneca, the American Pfizer and Moderna, and the German CureVac.
These are the deadlines handled by the European Union:
- Pfizer / BioNTech: emergency vaccination approved on December 21.
- Modern: emergency vaccination approved on January 6, 2021.
In parallel, the United Kingdom approved the use of the Pfizer and BioNTech vaccine on December 2, and began to apply it from December 8 in the most vulnerable population.
The local regulatory body also gave the green light to the AstraZenca / Oxford University (December 30, 2020) and Moderna (January 8, 2021) vaccines.
In Russia, the government began emergency vaccination of risk groups from December 5, 2020 with its antidote Sputnik V, although it has not yet been officially approved by regulatory authorities.
In Latin America, the initiation of vaccination will depend on the agreements they have reached with providers and the authorization process of internal regulatory bodies.
Either way, these are the deadlines that some of the region’s governments have announced:
- Argentina: At the end of December 2020, emergency vaccination with the Russian-derived antidote Suptnik V.
- Brazil: the Brazilian government has not started mass vaccination against COVID-19. However, the state of Sao Paulo has an agreement with the Chinese-origin antidote Sinovac, while the national authorities agreed to import the AstraZeneca / Oxford vaccine.
- Colombia: Authorities have confirmed that vaccination will begin in February 2021, when the first doses of the Pfizer / BioNTech vaccine arrive.
- Chile: approved the Pfizer / BioNTech vaccine and also hopes to do so with the AstraZeneca / Oxford vaccine. The vaccination process began in late 2020.
- Mexico: approved vaccines from Pfizer / BioNTech and AstraZeneca / Oxford. Also, consider buying the Russian Sputnik vaccine. Vaccination began in December 2020.
- Peru: the Peruvian government announced agreements with AstraZeneca / Oxford and China’s Sinopharm. The start of vaccination will be in January 2021, although the greatest effort will be in the following months.
- Uruguay: Authorities have said vaccination will begin in the first half of 2021.
