https://www.hopkinsmedicine.org/health/conditions-and-diseases/coronavirus/covid-natural-immunity-what-you-need-to-know
A later technical paper (from June, 2022 in the New England Journal of Medicine) on a study of natural and vaccine immunity:  https://www.nejm.org/doi/full/10.1056/NEJMoa2118946
A summary from Cornell of that paper stated: 
"A key finding was that a history of vaccination with the standard two doses of either the Pfizer or Moderna mRNA vaccine, but no history of prior infection, brought no significant protection against symptomatic omicron infection. Having a booster dose appeared to be about 60 percent protective, though most boosters were received just weeks before the omicron wave. Overall, the analysis suggested—consistently with prior studies—that mRNA vaccines and boosters work fairly well in protecting against symptomatic omicron infection, though their protective effect wanes rapidly and disappears within six months or so."

So point me where in your quote is mentioned efficiency of natural immunity or efficiency of vaccination after prior infection?

From the NEJM article, readily available on line, in the abstract: 
"The number of cases of SARS-CoV-2 infection per 100,000 person-days at risk (adjusted rate) increased with the time that had elapsed since vaccination with BNT162b2 or since previous infection. Among unvaccinated persons who had recovered from infection, this rate increased from 10.5 among those who had been infected 4 to less than 6 months previously to 30.2 among those who had been infected 1 year or more previously. Among persons who had received a single dose of vaccine after previous infection, the adjusted rate was low (3.7) among those who had been vaccinated less than 2 months previously but increased to 11.6 among those who had been vaccinated at least 6 months previously. Among previously uninfected persons who had received two doses of vaccine, the adjusted rate increased from 21.1 among those who had been vaccinated less than 2 months previously to 88.9 among those who had been vaccinated at least 6 months previously.""
You can read the entire article at your convenience.  You asked, "If government does not want scepticism [sic] on COVID vaccines, why they efing don't do [sic] proper studies with natural immunity taken into account?"

The problem is that some people who had the virus also died from it.

Countries that did not have good mRNA vaccines and did not have strict lockdown, such as Russia, had huge excess death rate during the pandemic. In Russia alone the official excess mortality figures were  over 800,000 or about 1% of adult population.

UK Vaccinations: 50m
UK cases: 20m

I'd say that's more likely due to vaccinations working rather than infections.

Except when it works for you?

--- Quote from: coppice on November 29, 2022, 10:13:28 pm ---Why did you assess the risks as small? mRNA therapies have a problematic history, and had never previously been deployed at scale. They have such a problematic history that the well funded Moderna was on the point of bankruptcy, because nothing was working out for them. I didn't take the mRNA vaccine, because I'm an engineer. I've seen far too many serious teething troubles with new technologies. A very conventional vaccine I would have taken without much thought. I eventually took the Moderna vaccine when other personal medical issues tilted the balance in favour of me taking it.

Because tens of millions of people had received it by the time I was eligible and now hundreds of millions have and we have enough data to say beyond any reasonable doubt that the vaccine is much safer than the Covid virus. Also I decided what the hell, I'll try it and see what happens. For some strange reason I have seen people who are extremely concerned about possible side effects of the Covid vaccine, yet they seem to have no such concerns about drinking excessive amounts of alcohol, smoking tobacco or using other drugs. Life is filled with calculated risks, I have seen no reason to believe that the Covid vaccines are not safe. At this point I've had four of them with no ill effects, aside from some fatigue for a few hours a day or so after receiving them. I've received vaccinations for variosu things throughout my life and evidence suggests to me that they are safe and effective.

From a recent data analysis: "COVID-19 is on track to be the third leading cause of death in the United States for the third year in a row. The virus claimed more than 340,000 lives in 2020, 475,000 lives in 2021, and so far, has taken 230,000 lives in 2022 through September."
