How can a vaccine have a negative effectiveness?
Are they implying it will make people more susceptible in the long term? That makes no sense at all.
I was scratching my head on that also.
I believe the negative effectiveness is due to vaccinated people who feel (as I do) that once you are vaccinated that's the end of COVID for you. If the vaccine stops having any effect after a period of time but you live without caring about COVID at all then you are more likely to get infected then a person who isn't vaccinated but is taking some level of precautions.Besides the ridiculousness of producing a graph that shows the vaccine eventually creating negative protection, their own conclusions of this study (that hasn't been peer-reviewed) is:
"Background: Whether vaccine effectiveness against Coronavirus disease 2019 (Covid-19) lasts longer than 6 months is unclear.""Collectively, there is insufficient evidence to determine vaccine effectiveness beyond 6 months.""The effectiveness against severe illness seems to remain high through 9 months, although not for men, older frail individuals, and individuals with comorbidities."
As far as how much to respect this study, it is a pre-print that will be printed in The Lancet, which is a highly respected publication.
