Claudio said there is no vaccine for HIV infection yet (and people still survive).

“Not very soon. RNA viruses change very quickly and this makes it difficult to create a good vaccine,” he said.

Elaborating on the Italian experience of Covid-19, — a possibility the population has developed herd immunity after experiencing the viral infection attack for close to 6 months — Claudio said, “No. Today the rate of immunization is in the order, depending on the areas, of 2-15 per cent. Very far from herd immunity.”
