Don't most other vaccines prevent the virus from actually entering your body?

No vaccine can prevent any virus from entering your body. If it's in your body, you are infected. What a vaccine can do is stimulate your body to respond to the virus when it sees it.
Ideally, antigen presenting cells(APCs) like Macrophages that are floating around in your blood will detect the presence of the virus and activate Tcells. Macrophages themselves will do the blob routine, surround something and eat it. They present signals that will stimulate Tcells and ultimately bcell antibodies to go on the hunt so to speak. How robust this process is will affect how many of your cells will get the virus injected into them. Ideally that number is zero, but even in the most robust immune response some cells will get the virus in them. Soon enough killer T-cells will come along and those hijacked cells will die.
This MRNA vaccine is only different in the mechanism by which is stimulates the immune system to respond. The actual immune response is the same. Your immune system sees an invader and attacks it. The MRNA vaccine hijacks your own cells, like a virus does except the vaccine does not make your cells create more of the vaccine. If it did, the result of a self replicating vaccine would surely be fatal.
