Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity
- hammock 5y agoThis large study shows through science and data that the vaccinated, as opposed to the naturally immune, are 13x more likely to catch Delta 6x more likely to catch COVID generally 7x more likely to be symptomatic More likely to be hospitalized for COVID From the study: >SARS-CoV-2-naïve vaccines had a 13-fold (95% CI, 8.08 to 21.11) increased risk for breakthrough infection with the Delta variant compared to those previously infected.... The increased risk was significant (P<0.001) for symptomatic disease as well. >SARS-CoV-2 naïve vaccinees had a 6-fold increased risk for breakthrough infection and a 7-fold increased risk for symptomatic disease [compared to previously infected.] They were also at a greater risk for COVID-19-related-hospitalizations compared to those that were previously infected. >This study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity.
- drewg123 5y agoDoes this imply that a vaccine based on a weakened live virus would be better than the mRNA vaccines? Or is the level of immunity somehow dependent on having a full blown infection? As somebody who has been mRNA vaccinated recently, should I seek out a break through infection by the Delta variant now, while my immune response is at its peak? Would that convey longer lasting immunity?
