Interesting study....One possible explanation I can come up with is "the virus never left"...so some groups may have been infected before vaccination... The study has several limitations. Individuals with unrecognized prior infection would have been misclassified as previously uninfected. Since prior infection protects against subsequent infection, such misclassification would have resulted in underestimating the protective effect of the vaccine. However, there is little reason to suppose that prior infections would have been missing in the bivalent vaccinated and non-vaccinated states at disproportionate rates. Those who chose to receive the bivalent vaccine might have been more worried about infection and might have been more likely to get tested when they had symptoms, thereby disproportionately detecting more incident infections among those who received the bivalent vaccine. This risk is mitigated by the time-dependent treatment of bivalent vaccination, because with such treatment, risk of disproportionate detection is actually in the opposite direction. DJ, lots of questions on both safety and effect of vaccines;

Not a single major news source reports this If FDA reported any other drug increased lung blood clots 50% can you imagine our media staying silent? DJ....[url]https://en.wikipedia.org/wiki/Antibody-dependent_enhancement[/url] or https://en.wikipedia.org/wiki/Antibody-dependent_enhancement - https://en.wikipedia.org/wiki/Antibody-dependent_enhancement could be a next step in this ongoing pandemic... I do not have enough knowledge on vaccines/imunology...(and I did get vaccinated 5 times...would hate it if it increased my healthrisks...) but vaccines as a strategy to end the pandemic seem to have made this pandemic WORSE !!!! Variants did get better in evading immunity....IF more vaccinated run MORE risks ; This is not the only study to find a possible association with more prior vaccine doses and higher risk of COVID-19. A large study found that those who had an Omicron variant infection after previously receiving three doses of vaccine had a higher risk of reinfection than those who had an Omicron variant infection after previously receiving two doses of vaccine [ https://www.medrxiv.org/content/10.1101/2022.12.17.22283625v1.full#ref-21" style='-webkit-font-smoothing: antialiased; margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 700; font-stretch: inherit; font-size: 14.7px; line-height: inherit; font-family: "Lucida Sans", Helvetica, Arial, sans-serif; text-decoration: none; color: gray; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);'>21 ]. Another study found that receipt of two or three doses of a mRNA vaccine following prior COVID-19 was associated with a higher risk of reinfection than receipt of a single dose [ https://www.medrxiv.org/content/10.1101/2022.12.17.22283625v1.full#ref-7" style='-webkit-font-smoothing: antialiased; margin: 0px; padding: 0px; border: 0px; outline: 0px; vertical-align: baseline; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 700; font-stretch: inherit; font-size: 14.7px; line-height: inherit; font-family: "Lucida Sans", Helvetica, Arial, sans-serif; text-decoration: none; color: gray; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255);'>7 ]. We still have a lot to learn about protection from COVID-19 vaccination, and in addition to a vaccine’s effectiveness it is important to examine whether multiple vaccine doses given over time may not be having the beneficial effect that is generally assumed. then the big question is why ???? Vaccine-immunity ends up in becoming MORE vulnerable ? A-symptomatic, only mild symptoms before vaccinations -could be a weak spot in these kinds of studies.... My conclusion is "vaccines are not the only answer"...maybe nasal/oral vaccines ; Got my booster today- the new CanSinoBio inhaled vaccine. Super easy, basically comes in a milk tea cup, you inhale, hold it, exhale- done. No taste really. Should improve vaccine rates here, and the efficacy is supposed to be decent.
will do better ? China moving in that direction...
