This week, clinical trials of the combination of the Sputnik V vaccine and the drug developed by AstraZeneca and the University of Oxford began.
The goal of combining the two vaccines is to see if this increases the immune response and improves protection against SARS-CoV-2, the virus that causes covid-19.
Experts explain that "the immunity created after the first injection of AstraZeneca prevents the second dose from being effective", presenting an overall efficacy of only 55%, unless there is a three-month wait.

"We are ready to develop cooperation with other manufacturers to increase the number of affordable and effective medicines," declared the general director of the Russian fund, Kiril Dmitriev, after considering that "to defeat the coronavirus it is necessary to join forces and use the most advanced solutions ”.
Already in December, British company AstraZeneca announced that it would start recruiting people over 18 years of age to participate in clinical trials that will combine the vaccine it develops together with the University of Oxford with the Russian Sputnik V vaccine, produced by the Gamaleya Institute in Moscow.
"Scientific collaboration with the Gamaleya Research Institute is important to explore the potential of the vaccine combination to unlock synergies in terms of protection and accessibility ... It is important to explore different combinations to help make immunization programs more flexible, allowing to scientists a greater choice when it comes to administering them ", as well as to improve" immunity in the long term, "he said in AstraZeneca in a press release.
Also in early February, the Azerbaijani Ministry of Health granted permission to conduct the world's first study of a combination of coronavirus vaccines, according to the Russian Fund for Direct Investments. This program will last six months, will be developed in different countries and is expected to have 100 volunteers in each stage.
