No!   Of all the elementary particles that we know of, neutrinos are the least harmful of them all. Millions of neutrinos coming from nuclear reactions in the Sun pass through our body every day without ill effects. The reason is that their interaction with human tissue is next to zero.  All charged particles, like electrons, protons, etc do interact and in sufficient quantities can be harmful.  Even some neutral particles like gamma rays or neutrons can be harmful since they have stronger interaction rates.
