Oxford dictionary defines vaccines as “substance[s] used to stimulate immunity to a particular infectious disease or pathogen”. So yes, covid vaccines do that.

  The CDC changed the definition of "vaccine", since, unlike previous vaccines, the COVID-19 vaccine did not produce immunity: Yes, the CDC changed its definition of vaccine to be 'more transparent' https://www.king5.com/article/news/verify/coronavirus-verify/cdc-changed-vaccine-definition-more-transparent/536-03ce7891-2604-4090-b548-b1618d286834 https://www.king5.com/article/news/verify/coronavirus-verify... > [T]he CDC changed its definition of vaccine from "a product that stimulates a person's immune system to produce immunity to a specific disease, protecting the person from that disease" to "a preparation that is used to stimulate the body's immune response against diseases."

    By your standard, if the covid vaccine doesn’t produce immunity then the flu vaccine doesn’t, either.

        No, I’m not. The semantic difference you insist upon is pointless. The mechanism of a flu or covid shot is exactly the same as any other vaccine; the only difference is the degree of efficacy due to human mucosal immunity not having evolved to fully block infection from respiratory viruses. https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1009509 https://journals.plos.org/plospathogens/article?id=10.1371/j...
