Another interesting field, which is my own, is cofactors, not only to the disease but also to transmission. I am still puzzled by the fact that you get more sexual transmission in some ethnic populations. One way to answer this is to look for genetic factors.

The idea of the live-virus vaccine is to produce in a continuous way some viral antigens.

It's clear that prevention will never be sufficient. That's why we need a vaccine that will be safe.

That is why it is so important not only to have excellent treatment but also to try to get back the immune defense, because there you have a natural defense that takes place everywhere.

It's easier to learn things for life by the age of 12 and not the age of 18. This is just my guess.

Since most of the transmission is sexual transmission, you have a regional or local response to the virus.
