The figures echoed similar findings from unpublished data on 3.8 million Russians, according to which Sputnik V demonstrated an efficacy of 97.7%. [207] A study published by the Journal of Medical Internet Research analyzed the dataset consisted of 11,515 self-reported Sputnik V vaccine adverse events posted on Telegram.
[2] The plasmid is produced using E. coli cells. [2] The vaccine is given as an intradermal injection using a spring-powered jet injector. [2] [3] This is because successful transfection of DNA vaccines requires traveling across both the cell plasma membrane and the nuclear membrane, [4] and using a conventional needle gives poor results and ...
A vaccine is generally considered effective if the estimate is ≥50% with a >30% lower limit of the 95% confidence interval. [6] As of September 2021, no study on Sputnik Light reported confidence intervals, so it is not possible to know the accuracy of the estimates. Effectiveness is generally expected to slowly decrease over time. [7]
In the UK, 15,121 health care workers from 104 hospitals who had tested negative for antibodies prior to the study, were followed by RT-PCR tests twice a week from 7 December 2020 to 5 February 2021, a study compared the positive results for the 90.7% vaccinated share of their cohort with the 9.3% unvaccinated share, and found that the Pfizer ...

[2] [3] The lack of protective effectiveness of EpiVacCorona, which is still in use in Russia, has been reported in scientific literature [4] and in the media. [ 5 ] [ 6 ] The vaccine consists of three chemically synthesized peptides (short fragments of a viral spike protein ) that are conjugated to a large carrier protein .
