| Taking a longer pause between the two required shots of Russia's Sputnik V vaccine against Covid-19 to speed up the global immunization campaign is viable, and may even build up a stronger immune response, its developer has said. | Taking a longer pause between the two required shots of Russia's Sputnik V vaccine against Covid-19 to speed up the global immunization campaign is viable, and may even build up a stronger immune response, its developer has said. |
| Like most other jabs designed to fight the coronavirus, Sputnik V is delivered in two injections administered weeks apart, with a booster shot ramping up the defense provided by the initial dose. Some countries such as Britain successfully experimented with an alternative immunization regimen, prioritizing giving as many people as possible the first jab and postponing the second one beyond what is recommended by producers. | Like most other jabs designed to fight the coronavirus, Sputnik V is delivered in two injections administered weeks apart, with a booster shot ramping up the defense provided by the initial dose.

| Officially called “Gam-COVID-Vac”, the vaccine developed by the Gamaleya lab was the first to be registered in Russia. It is being offered domestically and to the global market under the brand name Sputnik V. Some 60 nations have approved its emergency use. | Officially called “Gam-COVID-Vac”, the vaccine developed by the Gamaleya lab was the first to be registered in Russia.

| Unlike other vaccines, Sputnik V’s two shots are slightly different, using two strains of human adenovirus as the delivery mechanism. The same platform has been extensively tested in vaccines against other diseases, which helped the lab to develop the new medicine at short notice. Russia itself does not plan to use the altered injection regimen, Gintsburg noted. | Unlike other vaccines, Sputnik V’s two shots are slightly different, using two strains of human adenovirus as the delivery mechanism.

| Single-shot vaccination with Sputnik V was previously suggested by the vaccine's global promoter, the Russian Direct Investment Fund, which dubbed this regimen ‘Sputnik Light’. | Single-shot vaccination with Sputnik V was previously suggested by the vaccine's global promoter, the Russian Direct Investment Fund, which dubbed this regimen ‘Sputnik Light’. |
