"According to preliminary results, which were obtained on the basis of data from more than 5 thousand people, after the second dose, more than 99% of [study participants] developed antibodies," TASS quotes him as saying.

According to Cavalli, the Roman Institute will have to conduct a "qualitative analysis of these antibodies."

He clarified that the study is still ongoing.

He said that Sputnik V vaccinated almost 20 thousand residents of San Marino, which is about 2/3 of the population.

Earlier, the head of the Ministry of Health of San Marino announced the political factors in the situation with the approval of "Sputnik V" in the EU.
