There probably needs to be some thought about how immunization will affect evolution of the virus and how to get best long term outcomes which may be a significantly different strategy than fighting short term outcomes.
However many people have turned one approach into a morality issue and so any deviation from this (or opposition to this) will be difficult.
Natural non-sterilizing immunization will also cause evolutionary pressure. Not quite as focused on one protein plan (some immune systems might have won their first encounter using a different part as target), but still pressure. Long term the virus will be with us and factor into our life expectancy wether we like it or not (nobody will really care as long as the transition is soft) and wether immune systems are kept trained by infections alone or by infections and the occasional vac shot. I certainly prefer the latter.
