According to this, most vaccines are as you describe:
"There are two main types of immunity you can achieve with vaccines. One is so-called 'effective' immunity, which can prevent a pathogen from causing serious disease, but can't stop it from entering the body or making more copies of itself. The other is 'sterilising immunity', which can thwart infections entirely, and even prevent asymptomatic cases. The latter is the aspiration of all vaccine research, but *surprisingly rarely achieved*." https://www.bbc.com/future/article/20210203-why-vaccinated-people-may-still-be-able-to-spread-covid-19
Side note—I wonder if these scientists were inspired by Spider-Man (1962):
"Nearly 40 years ago it was observed that sterilizing immunity against [Malaria] could be achieved by exposing human volunteers to the bites of irradiated mosquitoes carrying sporozoites in their salivary glands." https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/sterilizing-immunity
