In an interview with The Sunday Times, Executive Director of AstraZeneca Pascal Sorio said the developers of the AZD1222 vaccine have discovered a 'success formula' that will have a positive impact on the effectiveness of the vaccine.

“We believe we have discovered a success formula and the way to achieve high indicators of effectiveness after two injections,” Sorio said, yet failed to provide details.

In November, the specialists tested AstraZeneca’s vaccine with two options for injection, and in both cases, the results varied. They assessed the average effectiveness of the vaccine to be 70%.

As of today, there are already a few vaccines against the coronavirus. Russia has registered two local vaccines (Sputnik V and EpiVakCorona). Vaccination with Sputnik V was launched in Moscow on December 5. The US and the UK have started vaccinating the population with the vaccine developed by Pfizer/BioNTech. In addition, the vaccine developed by well-known businessman Noubar Afeyan’s Moderna company has also been permitted.
