Covid, “third dose of vaccine: what risks those who don’t do it”

Covid, after the third dose “protection for at least 1 or 2 years, maybe even longer”

What happens to those who don’t get the third dose of Covid vaccine? Affaritaliani.it he asked Fabrizio Pregliasco, member of the Cts of Lombardy and medical director of the hospital Galeazzi from Milan. “After six months from the second dose, there is a reduction in protection of up to 50% to avoid becoming infected with Covid, but the possibility of avoiding severe forms of the disease, up to death, remains high enough. It starts from an average protection of 95% at the end of the second dose of vaccine and then drop to 85% after six months. This applies to both men and women and more or less for all age groups, except for a few situations slightly worst for the elderly“.

As for the different vaccines, explains the virologist, “Johnson & Johnson has a protection, having had only one dose, a little weaker. Modern is perhaps a tad bit better than Pfizer, but it changes very little. “And Astrazeneca?” The ideal is the third dose of Pfizer after two of Astrazeneca, in this way the so-called heterologous vaccination, highly protective. ”And finally the question that everyone asks, how long will the protection of the third dose of coronavirus vaccine? “From the studies that have been done, it seems that protection from Covid is more prolonged over time, at least a year or two. Maybe even over 24 months“, concludes Pregliasco.
