Burioni: “From polio to hepatitis B, many vaccines require three doses”

“Do you know that the vaccines against polio, tetanus, hepatitis B, haemophilus, pertussis, diphtheria (here I stop but I could continue) all have three doses? Strangely, no one finds anything to object”. This was underlined on Twitter by the virologist of the Vita-Salute San Raffaele University of Milan, Roberto Burioni.
