Alexander Gintsburg, head of the Gamaleya Center, in a radio interview with Sputnik News Kazakhstan: No severe side effects have been recorded during the mass Sputnik V vaccination campaign.
Alexander Gintsburg: All batches of Sputnik V are undergoing strict quality control at the Gamaleya Center. The high quality of the vaccine is guaranteed.
Alexander Gintsburg: Sputnik V vaccine fully protects from the UK variant of COVID-19, studies on other variants are ongoing, results will be available in about one to several weeks.
Alexander Gintsburg: People with high antibody level after vaccination cannot transmit the virus. After the level falls, a vaccinated person may transmit the virus without showing any symptoms so protective measures should remain in place during the vaccination campaign.
Alexander Gintsburg: If a vaccinated person is completely isolated the antibody level will inevitably fall in 4-5 months. It does not mean this person will lose protection since the cells will produce antibodies in sufficient quantities after a new contact with the virus.
Alexander Gintsburg: Time gap between 1st and 2nd Sputnik V shots could be increased to 60 days from 21 days without lowering the vaccine’s efficacy. Children will receive a lower dose depending on age and weight.

1. Immunity created by the first AZ shot prevents the second shot from being effective (overall efficacy of only 55%) unless there is a wait of 3 months
2. Sputnik V solves this elegantly through heterogeneous boosting (using a different second shot)
3. Using Sputnik V shot as a second shot for AZ vaccine will eliminate the need to wait for 3 months. Clinical trials of this approach have already started.
In response to EU leadership question on why #SputnikV vaccine is offered to EU while vaccination in Russia is not yet complete:
1. Mass doses of Sputnik V for Europeans have been offered after EMA approval and after mass vaccination in Russia is complete in June, 2021. This timeline can be accelerated by engaging EU production facilities that are waiting for EMA approval.
2. In the meantime, Russia will supply doses to Hungary and some other EU nations that decided to order Sputnik V directly
7 facts about the mass scale #SputnikV vaccination in light of publication of many misinformed articles that have been appearing in the media since the start of mass scale vaccination in Russia.
[1/7] Currently, there are only 4 vaccines in the world that published phase 3 results in this order: Pfizer, Sputnik V, Moderna, AstraZeneca. #SputnikV has significant advantages in Safety, Efficacy, Price and Logistics.
[2/7] As of now, Russia, China and UAE are the only three countries in the world that vaccinate people outside of clinical trials.
