The definition of vaccine has not been changed. There is a formal definition which has been pretty consistent since the discovery that inoculating people with cowpox could boost the immune response against smallpox (cow <-> vaca -> vaccine)
It's worth noting that the flu vaccine does not stop all variants of influenza either. The notion that a vaccine will magically stop any and all variants of a virus is naive.
Also, since you did no homework, here's the definition of vaccine:

The CDC did change their definition of 'vaccine' and 'vaccination'.
​
"Social media is calling bluff on the Centers for Disease Control and Prevention for modifying its definition of the words “vaccine” and “vaccination” on its website. Before the change, the definition for “vaccination” read, “the act of introducing a vaccine into the body to produce immunity to a specific disease.” Now, the word “immunity” has been switched to “protection.” The term “vaccine” also got a makeover. The CDC’s definition changed from “a product that stimulates a person’s immune system to produce immunity to a specific disease” to the current “a preparation that is used to stimulate the body’s immune response against diseases.”

This is interesting information.
I did a little deeper digging to see what I could find about vaccines and breakthrough infections. It turns out there are a number of diseases which have breakthrough infections including, but not limited to, COVID-19, influenza, mumps, and chickenpox.
Most recently, a smallpox vaccine has been used to stimulate the immune system to fight monkeypox, which has seen breakthroughs in France.
I wonder whether COVID-19 was the genesis of the change, or simply the final straw.
