1/ “Fully vaccinated were more likely than unvaccinated persons to be infected by variants carrying mutations associated with decreased antibody neutralization.”, and “In unvaccinated cases, most viruses consisted of non-resistant variants” 
2/ In addition, the increase in the frequency of more antibody-resistant strains in the population correlates with the increase in the frequency of vaccination in the population
3/ “and the percentage of sequenced cases that were vaccine breakthroughs increased from 0% to 31.8% from February to June”
4/ and “Differences in viral loads were non-significant between unvaccinated and fully vaccinated persons overall (p = 0.99)”
5/ Reference: medrxiv.org/content/10.110…
6/ To be clear: This data is not showing that vaccinated people are becoming infected at a higher rate than unvaccinated. Breakthrough % according to the most recent data is about 30% (as of June) of cases (see 3rd point). It would be good to know current % (Oct)
7/ The data shows that vaccinated people preferentially incubate antibody-resistant strains.
8/ This 30% breakthrough rate should be contrasted against the much higher breakthrough %’s occurring in the UK and Israel.
