Weird. I like my doctors to be 100 % right

Your doctor is partially right.
The first thing is that studies have shown that the natural antibodies 'wear' off in effectiveness in a few months, so, there's that.
Also, the natural antibodies may be more specific in the strains of Coronavirus they work against and may not help that much as strains mutate over time.
The COVID-19 vaccines all produce antibodies to particular parts of the viral coat which are unlikely to change as much (without invalidating the virus). That was part of the design because they wanted vaccines that didn't become useless against the virus in a month or so, so they had to look for targets that had some genomic stability.

Did you tell her that getting the vaccine within 90 days of having had Covid is harmful?
So say other doctors.

Your research indicates that the current vaccines also work against the known variants? If so, that's a good thing.
The FDA told the vaccine manufacturers last week that they are free to adjust the formulas without testing them, in order to combat the Covid19 variants that appear.

I didn't know that until seeing your post tonight.
So the efficacy of the flu shot isn’t between 10-30 percent every one of those years?

Have you ever noticed that there is a new Fluvax every year?
Do you imagine that there is a full process initiated to recertify and retest for perhaps 18 months t two years before releasing the latest Fluvax?
There is precedent on vaccines where the changes are small and incremental, and to keep track with mutations of a pathogen.
You’re right probably. I won’t believe anything ever again if it’s sold by “medical authority”

Good luck with that.

All I heard was “yes, but the Covid vaccines weren’t even researched nearly as much nor for as long as the flu shot”

Yes, but in the case of the Fluvax, it doesn't have the specificity of an mRNA vaccine, but is usually a 'killed' mutated virus taken from a cultured colony of what is assumed to be the latest strain.
So the Fluvax tracks the current strains, but often the specifics of the changes are fairly broad and are unknown until a genomic assay can tell us what the differences are. The thing is, the Fluvax has been approved in principle and reduced testing is allowed because the disease it immunizes for keeps changing.
These changes, combined with the usual lead time of 28 days before a vaccine really begins to elicit a strong antibody response, mean that if you hang around waiting for minor changes to be approved, you could end up with a near useless vaccine that only works for older strains.
So, the approval process for a modified existing vaccine is shorter, and we do have good safety of these new vaccines because we can see how they have performed historically, and which assures us that the 'threat' of new mods to the vaccine confers very little risk in practice.
