More than 80% of Americans 16 and older have some level of immunity against the coronavirus, mostly through vaccination, a survey of blood donations indicates...
They worked with 17 blood collection organizations working in all 50 states plus Washington, DC, and Puerto Rico to test blood covering 74% of the population. In the end, they tested about 1.4 million samples.
In July 2020, before any vaccine was available, 3.5% of samples carried antibodies to SARS-CoV-2, the virus that causes COVID-19. That rose to 11.5% by December, they reported in the medical journal JAMA. By May, 83.3% of samples had antibodies to the virus, most of them from vaccination.

Actually, it's considerably less than 10% immunity. People who are immune to the original strain are not immune to newer strains such as Delta.
in my opinion if you get the vax your playing Russian roulette with your life
The fatality rate per 100,000 people ranged from 3.3 in the District of Columbia to 25.4 in Wyoming.
Really? Chances are 1 out of 6 that you will die if you get vaccinated?
Of course, it seems happen with COVID infections as well.
rare event after other vaccinations as well
This study from the COVID-19 Infection Survey is the largest to evaluate, and directly compare, the real-world effectiveness of the Pfizer-BioNTech and Oxford-AstraZeneca vaccines against all infections, including those without symptoms, after the Delta variant has dominated. It is the first to show how protection against COVID-19 infections changes over time following second vaccinations in a large group of adults from the general population.
