As I understand it, they reduce the chance of you being ill, and mean your body is better prepared to fight it off quicker, so there may be a shorter period in which you can pass it on, but I dont think they reduce you risk of passing it on while actually infected ? |
Here is some stuff on that:

Dr Peter English, a retired consultant in communicable disease control and former editor of Vaccines in Practice, told Full Fact via the Science Media Centre: “We know that two doses of Covid-19 vaccines reduce your chances of being infected and passing the disease on to others to about 20%.
“Some would say in response to that "so it doesn't prevent onward transmission" and they'd be right that it doesn't completely prevent this; but it does reduce the chances by about 80%. So others would say "it does prevent onward transmission [by about 80%]".
However, more recent data suggests that vaccination may not hugely reduce the risk of transmitting the Delta variant within households. A study published in The Lancet Infectious Diseases in October, which measured the likelihood of catching the Delta variant from someone else in your household, found a fully vaccinated individual has a 25% chance of catching the virus from an infected household member, while an unvaccinated person has a 38% chance.

So yes although less so if you're in the same household (which i guess means prolonged exposure to the virus).

And obviously if you have a reduced chance of getting it then you can't spread it at all.
