Sputnik Light is an effective universal booster for AstraZeneca, Sinopharm, Moderna and Cansino vaccines, ”reads a press release from RDIF.

Each combination of Sputnik Light with other drugs in a study in Argentina "stimulated higher titers of antibodies on the 14th day after the second injection" compared to a homogeneous vaccination schedule with individual drugs, the Foundation noted.

In addition, according to the interim findings of the study, a high safety profile of Sputnik Light was demonstrated in combination with all other vaccines with “no serious side effects after vaccination in any combination”.

As RDIF said earlier, a study in Argentina showed that a booster shot of the Sputnik Light vaccine produces a strong immune response.
