A study by the ministry of health of Argentina’s Buenos Aires province to monitor the safety of the Sputnik V vaccine claimed that the Russian vaccine against coronavirus, Sputnik V, has demonstrated the best safety profile among all vaccines used in the province.
According to the data collected between December 29, 2020, and June 3, 2021, with 2.8 million doses administered, Sputnik V recorded the lowest ratio of serious adverse events.
The official handle of Sputnik V tweeted, “#SputnikV shows the safest profile among #COVID vaccines used in the Buenos Aires province in Argentina, no deaths related to vaccination recorded — the province Health Ministry.”
According to the data of the Argentina Health Ministry, the Events Supposedly Attributable to Vaccination or Immunization (ESAVI) were mostly mild. Among the most frequent are fever (47%), headaches (45%), myalgias and arthralgias (39.5%) and pain (46.5%) and swelling (7.4%) in the area where the vaccine was injected.
The efficacy of Sputnik V is estimated to be 97.6% based on the analysis of data on the coronavirus infection rate among those in Russia vaccinated with both components of Sputnik V from December 5, 2020, to March 31, 2021.
Additionally, researchers have noted that Sputnik V uses two different vectors for the two shots in a course of vaccination, providing immunity with a longer duration than vaccines using the same delivery mechanism for both shots. Kirill Dmitriev, CEO of the Russian Direct Investment Fund (RDIF), said: “From the global experience we see that Sputnik V has the best safety profile compared to other vaccines. This is confirmed by international data coming from both national and regional ministries of health in several countries in various regions of the world, where Sputnik V is successfully used to protect the population.”
