Covid vaccine, Capua: “We have to use third dose”

“We have to use the third dose, of course.” Professor Ilaria Capua, director of the UF One Health Center at the University of Florida, thus answers the questions of In Onda, on La7. “The fourth wave of covids today is taking place in those areas of Europe where the vaccination coverage rate is very low: Romania, Bulgaria, Russia have very low numbers. We cannot compare” the situation in Italy to that of countries “that do not they applied a vaccination strategy as essential. ” “I would look at the glass half full: Italy, Portugal and Spain have the highest vaccination coverage rates. We have the third dose and we have to use it because immunity drops. Immunity remains the same for very few infections, for the vast majority there is. it is a decrease in antibodies. The wall against the infection is at the beginning one and a half meters high, when it decreases and goes down to 50 centimeters it is necessary to intervene. We have to use the third dose, of course, “he adds. Merck and Pfizer have produced pills anti covid which appear to have very high efficacy. “The vaccine prevents. The anti-covid pill intervenes later, when the virus has already begun to replicate. Antiviral drugs are effective in 50-60% of cases: not all of them come out and the organism suffers. The virus, however, causes a problem. damage and that is why we must invest above all in prevention. Of course, the pill is another resource “, says Capua. “Vaccinating younger children interrupts the chain of contagion and avoids secondary bacterial infections, which should be treated with antibiotics.”
