Can you link to where anybody has redefined vaccine, and also evidence that the vaccinated become more likely to catch it than the unvaccinated? All that sounds like complete baloney.
Here you go - maybe you can reconsider your priors for classifying things as baloney now? Gov and media put a lot of effort into breaking our intuitions about their trustworthiness. Your gut reaction is the one we're trained to have.
CDC changed their definition of vaccine and vaccination:
> 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.”
> Merriam-Webster revised its "vaccine" definition to replace "immunity" with "immune response."
This was done when it became clear that COVID vaccines didn't actually create any kind of immunity and thus weren't technically vaccines. Like always in public health they fixed this problem by manipulating language - now it only has to provoke some sort of response from the body. If that response turns out to be useless or actively harmful, no big deal, it's still a vaccine.
Observe that this change totally alters the meaning of being anti-vaxx. Take a substance that provokes an immune response but it's the wrong sort of response and doesn't work, diverting the immune system into wasting time whilst the virus replicates. It is 100% rational to oppose such a useless product, but by subtly manipulating the definition of vaccine they have now trained people to consider such opposition anti-vaxx and therefore automatically irrational.
Unfortunately this problem is not theoretical, bringing us to negative efficacy. It exists and is visible in many studies, but hidden by governments which use a variety of invalid statistical methodologies to alter the raw data, which is kept secret. Nonetheless, they aren't the only ones that can count cases. It's a big topic but some studies and explanations of what's going on can be found here:
The root biological cause seems to be related to the definitional game playing. The vaccines targeted the 2019 Wuhan spike and the antibodies vaccinated people produce are meant to dock with those specific proteins. But by the time vaccination is rolling out big time we are already at Delta, the virus spike has evolved quite significantly and the antibodies aren't so effective anymore. The body doesn't seem to recognize this quickly enough and spends a lot of time producing the wrong sort of antibodies, thinking it's successfully fighting the invader. Unvaccinated people have immune systems that haven't been trained in any way, so their first real SARS-CoV-2 infection triggers the antibody learning process immediately and they develop immunity to the latest version of the virus quicker.
This problem is called imprinting and is visible in the booster and bivalent trials. They didn't help reduce COVID cases and even made them higher - actually 100% of test subjects got COVID when exposed in the bivalent trials, but the vaccines were approved anyway because under the new definition they only need to provoke an immune response of some kind, not create immunity. Public health responded to failure by conflating the means and the end.
The media never covered any of this and systematically attacked the independent bloggers and researchers who did. Which is why smart people don't trust them.
