Building immunity via vaccines rather than naturally deprives the living virus a potential host to evolve in. It also means you don't have to contract the virus in order to build immunity, meaning the first time you get the virus, a vaccinated person's body would be more prepared, which means more people could more contract the disease at once, without collapsing the health system - allowing it to be safer at the community level to free up movement. I just think you misunderstood the reasoning, you weren't being "lied to".
