First....
Makary is a surgeon, not an epidemiologist or immunologist.
In his profile, he lists no such expertise.
Martin Adel Makary, M.D., M.P.H., Professor of Surgery | Johns Hopkins Medicine
Johns Hopkins has one of the best public health grad
schools in the country, so it does have epidemiologists,
& they operate JHU's Covid 19 resource website.
I've not seen Makary present supporting research confirmed
by peers in appropriate fields.
Second....
The Johns Hopkins website doesn't support the views
attributed to Makary. (Was he accurately represented?
The sources claiming this look non-mainstream.)
COVID Natural Immunity: What You Need to Know
Excerpted....
If I have natural immunity do I still need a COVID vaccine?
Yes, the COVID-19 vaccines are recommended, even if you had COVID-19. At present, evidence from Johns Hopkins Medicine and the U.S. Centers for Disease Control and Prevention (CDC) supports getting a COVID-19 vaccine as the best protection against getting COVID-19, whether you have already had the virus or not.
:
Johns Hopkins has conducted a
large study on natural immunity that shows antibody levels against COVID-19 coronavirus stay higher for a longer time in people who were infected by the virus and then were fully vaccinated with mRNA COVID-19 vaccines compared with those who only got immunized. (The results of the study were published in a
letter to the Journal of the American Medical Association on Nov. 1, 2021.)

Vaccine immunity differs from natural immunity
The former can enhance the latter.
How Immunity Generated from COVID-19 Vaccines Differs from an Infection
Excerpted....
These findings suggest that natural immunity and vaccine-generated immunity to SARS-CoV-2 will differ in how they recognize new viral variants. What’s more, antibodies acquired with the help of a vaccine may be more likely to target new SARS-CoV-2 variants potently, even when the variants carry new mutations in the RBD.
Finally, regarding conflicting info....
With SARS Cov-2 being a novel virus, expert understanding
of Covid 19 is evolving. You needn't presume that differences
of opinion are due to "lying". In such an informationally dynamic
situation, I approach info with caution....take the safest course.
For example, vaccinations are low risk with great potential
benefit. So even if an unvaccinated person had Covid 19, it
makes sense to get vaccinated because it would be likely to
provide optimum immunity.
