The agency of ADE in Covid9 infection seems circumstantially correlated by so many Covid19 vaccinated persons getting a Covid19 infection far sooner than any study indicated their vaccination derived immunity might have passed.
It appears so many “fully vaccinated” persons are both getting a Covid19 infections and the same who are needing hospitalization that great effort MUST be put into the research to determine how much of a role that ADE is playing in that.
what many breakthroughs?
unvaccinated who survive one infection have about 80% protection over reinfection; over 65 less than 50%. Unlike vaccinated reinfected, unvaccinated reinfected tend to have more severe disease the second time around. Similar to vacccinated immunity, ‘natural immunity’ fades over time and immunity to Wuhan version doesn’t mean immunity to Delta or other variants. Many vaccinated reinfected were captive audience nursing home residents repeatedly exposed to unvaccinated caregivers. Many unvaccinated reinfected were exposed by their own social patterns.
reinfection rate among unvaccinated last year was 5%, a rate 2.5x that of vaccinated elderly.
among Kentucky residents who were previously infected with SARS-CoV-2 in 2020, those who were unvaccinated against COVID-19 had significantly higher likelihood of reinfection during May and June 2021... a recent laboratory study found that sera collected from previously infected persons before they were vaccinated provided a relatively weaker, and in some cases absent, neutralization response to the B.1.351 (Beta) variant when compared with the original Wuhan-Hu-1 strain (1).

from a qatar study - avg age 33 (blind test: swabs didn’t know what nose they were going up):
vaccinated pcr test at airport 0.8%
unvax prior inf pcr airport test 1%
unvax no prior pcr airport test 3.8%
