This is the study below is based the best data set we have. The Israeli data.
a. n
atural immunity was 13 times better than no covid but fully vacinated.
and
naturally immunity was 7 times superior than fully vaccinated for avoiding symptomatic disease.
And when you realize Symptomatics are all the very vast majority of the spreaders... .
Per science and data Cam New is vastly safer than every guy playing who is fully vaxxed but never had covid.
Results SARS-CoV-2-naïve vaccinees had a 13.06-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection with the Delta variant compared to those previously infected, when the first event (infection or vaccination) occurred during January and February of 2021. The increased risk was significant (
P<0.001) for symptomatic disease as well. When allowing the infection to occur at any time before vaccination (from March 2020 to February 2021), evidence of waning natural immunity was demonstrated, though SARS-CoV-2 naïve vaccinees had a 5.96-fold (95% CI, 4.85 to 7.33) increased risk for breakthrough infection and a 7.13-fold (95% CI, 5.51 to 9.21) increased risk for symptomatic disease. SARS-CoV-2-naïve vaccinees were also at a greater risk for COVID-19-related-hospitalizations compared to those that were previously infected.
