How long will it take to vaccinate the whole planet? More than 50 countries have requested Russian vaccine Sputnik-V for more than 1.2 billion people, adding up to 2.4 billion doses, bearing in mind that it takes two doses a person. Worldwide distribution will be carried out by international partners of the Russian Direct Investment Fund (RDIF) in India, Brazil, China, South Korea and other countries.

Sputnik-V has been certified in 17 countries, in its clinical test after the certification, more than 31 thousand volunteers took part in Russia and the clinical testing Phase III have taken place in the United Arab Emirates, India, Venezuela and Bielorussia.

The dose of the Russian vaccine will cost about 10 dollars (it takes two doses). The lyophilized (dried) form of the vaccine can be stored between +2 and +8 degrees Celsius (between 35 and 46 degrees Fahrenheit) so it´s easy to distribute, including regions that are very hard to reach.

Sputnik-V is one of the world’s three vaccines that has been proven to be more than 90% efficient, it´s been determined to be 91.6% efficient based on 19 thousand 866 volunteers who were administered the first and second injections or a placebo, there were 78 confirmed COVID19 cases in the final stage of the final control.


The so-called “vectors” are used to introduce genetic material inside another virus in a cell, it´s the adenovirus gen causing the infection, it´s subtracted and inserted in a gen containing the code of another virus protein. The inserted element is safe for the organism and helps the immunological system to react and produce antibodies, which protect us from infection.vaccine

The technological platform of adenoviral vectors generates new vaccines in a fast and efficient fashion, modifying the original transmission vector with genetic material of new viruses, which allows medical scientific researchers to obtain vaccines in short periods. Those vaccines provoke a strong reaction in the human body, aiming to create immunity.

Human adenovirus are considered to be among the easiest ones to modify with that goal in mind. That is why they have come to be very popular vectors.

Los adenovirus humanos están considerados entre los más sencillos de modificar con estos fines. Por eso se han convertido en vectores muy populares.
