Now there are also the first positive indications that the risk of transmission of the virus appears to be reduced in vaccinated “underlines Andrea Ammon, director of the ECDC, the European Center for Disease Control.” Although the effect of the variants must be carefully monitored – he adds -, we expect that the total number of infections will decrease significantly as vaccination coverage increases“.

Some key points emerge from the ECDC report. “Evidence of the impact of vaccination on transmission risk is available from only one study, which suggests that vaccinating one family member reduces the risk of infection in the others by at least 30%.” But it has been “proven that.” vaccination significantly reduces symptomatic or asymptomatic infection in vaccinated individuals, although efficacy varies by vaccine product and target group “. There are also”some evidence of a lower viral load and a shorter duration of diffusion in vaccinated individuals, which could result in reduced transmission “of Covid-19. Many of the studies on the effectiveness of the vaccine, however, notes the ECDC,” were conducted before the emergence of the variants of Sars-Cov-2 that are of concern and there is some evidence that vaccine efficacy may be reduced for some of the variants“.
