    Pár szakértői vélemény a Sputnikról, miután megjelent a Lancet cikk. Függetlenül, hogy jó lett a vakcina, sokan kiemelték az etikai kérdéseket.

    expert reaction to study looking at preliminary efficacy and safety results from interim analysis of Russian COVID-19 phase 3 vaccine (Sputnik) trial | Science Media Centre

    “The Russian government rolled out this vaccine before clinical efficacy was proven, although good immune responses had been shown in phase 2. Whether this was the right decision or not has now been overtaken by these results, although such a rollout would not have been considered ethical in the more heavily regulated, western nations.

    “This phase III trial does not tell us if this vaccine reduces transmission.
    “Implementing a vaccine in a large population before seeing your phase III results is hugely risky, and is definitely not to be recommended. The ethics of giving a product that has the potential to make you ill (or iller) is hugely different when you’re giving a vaccine to a large number of healthy patients, than when you are giving a medicine to a seriously ill patient, who might be prepared to take a risk. Apart from not knowing about efficacy or likelihood of harm, there is the potential to severely damage confidence in all other vaccines. However, knowing what we know now, it will have been a good decision. It is possible that the Russian regulators knew more than was in the public domain at the time, which might justify it.”

    “In this context, I look forward to seeing similar data/reports on the Chinese Sinovac/Sinopharm vaccines – as well as hearing how the Oxford-AZ and Russian Sputnik V teams might be collaborating to enhance and maintain the performance of their Ad-vectored COVID-19 vaccines – especially when both vaccines (and the recent Johnson & Johnson Ad26 vectored COVID-19 vaccine) are at risk of host-immune mediated neutralisation of their Ad vectors in the future – if repeated seasonal COVID-19 vaccine boosters are needed.”
