> completely new type of vaccine

Then is it a vaccine at all? Vaccines were traditionally live, dead, or attenuated virus/bacteria injections, some with adjutants, to stimulate an immune response.

Technologically speaking, it's bicycle vs airplane. Similar underlying purpose, entirely different implementation.

Both a bicycle and an airplane are transportation vehicles. Likewise, anything that illicits imunity is a vaccine, regardless of how novel the approach is.
