The 6 vaccines against COVID-19 that are very advanced according to the WHO


These are the 6 vaccines against COVID-19 that the WHO is targeting to curb the pandemic and are currently being tested in thousands of people.

The race to find the first safe and effective vaccine against COVID-19 is about to enter its peak.

Of the more than 165 candidates around the world registered by the WHO, 26 have started clinical trials and according to the agency, 6 are in a “very advanced and hopeful” phase to stop the pandemic that in seven months accumulates 17 million positive cases and 716 thousand fatalities:

The 6 vaccines against COVID-19 that Tedros Adhanom referred to are:

ChAdOx1 nCoV-19, the vaccine developed by Oxford University and AstraZeneca, which has shown the ability to offer double protection and is already being tested on tens of thousands of people around the world.

mRNA-1273, the vaccine of Moderna, Inc. and the United States National Institute of Allergy and Infectious Diseases (NIAID), which passed phase 2 last month and will begin testing more than 30,000 people in the US.

BNT162b2, immunization developed by the American pharmaceutical Pfizer and the German biotech company BioNTech, which is currently being tested in 120 locations around the world, such as Argentina, Brazil and Germany.

-The vaccine from the Chinese biotechnology company Sinovac Biotech, which begins phase 3 of human clinical trials in Indonesia and Bangladesh.

-The development of Wuhan and Sinopharm Biological Products Institute, a vaccine that has already been tested in its employees and is currently going through phase 3, with a study of 15 thousand participants in the United Arab Emirates.

Despite optimism due to the intense scientific work that is currently being carried out, the approval of a vaccine will be only the first step in a long way to achieve its mass production and subsequently, its worldwide distribution.

Against this background, the Director-General of WHO spoke out against the vaccine nationalism, an expression he used to call for both a multilateral cooperation that allows us to know useful scientific findings to find the cure for the coronavirus, as well as a political commitment that allows to ensure that once it is ready, immunization can reach the whole world.

The Global Alliance for Vaccines and Immunization (GAVI) is an association that tries to mediate between the WHO, the governments of different countries and pharmaceutical companies to reach agreements on the purchase, sale and fair distribution of vaccines around the globe.

In the case of the long-awaited vaccine against COVID-19, the agency has required both pharmaceutical companies and the countries that collaborate in its production, to offer the vaccine at cost, that is, without receive profit therefore, a proposal previously prepared by the WHO.
