(CNN Spanish) -

The process to apply the covid-19 vaccine will be the priority issue in the world in the coming years as countries try to fight the coronavirus pandemic.

What is the best or most effective covid-19 vaccine?


The Sputnik V vaccine is 91.6% effective in preventing symptomatic covid-19 and 100% effective in preventing severe coronavirus disease, according to an interim analysis of data from the phase 3 trial, published in the medical journal The Lancet.

Several countries in Latin America will receive the Russian vaccine.

The high effectiveness of the Sputnik V vaccine, which received criticism in 2020 because it was approved and rapidly deployed, is close to the most successful ones such as that of Pfizer / BioNTech - which is already applied in Europe and the United States - which reports an effectiveness of 95% to prevent symptomatic infections, and Moderna's vaccine, which is 94% effective in preventing symptomatic infections.

On the other end of the spectrum is the Sinovac vaccine, which is just 49.62% effective on average, and the Johnson & Johnson vaccine, which is 66% effective.
