You're 5x less likely to get COVID if you are vaccinated. You can't spread a disease you haven't caught.

I see. Perhaps I'd believe more into that if Pfizers research wasnt the only one that agrees on that while every single independent research says it doesnt stop the spread, just symptoms and hospitalisation or eventual death with older and weaker people

What's it like lieing? Plenty of research has been done that consistently shows all vaccinations slow spread.

You can just look at the daily case numbers in vaccinated and unvaccinated. Fully vaccinated Americans outnumber anti-vaxxers 2:1 and they're still coming down with covid at lower numbers daily. https://covid.cdc.gov/covid-data-tracker/#rates-by-vaccine-status

This figure is outdated since the Delta variant. Studies show the effectiveness against infection to be around 50-60% for Pfizer/BioNTech and 70-75% for Moderna once a few weeks have passed since the second dose.
There are tons of studies from various places which are all confirming a VE against Delta in this ballpark. To link just one example:

While he was clearly referring to the old strains where his claim is wrong, he ironically isn't that wrong when it comes to Omicron. Various preliminary studies show a ~40-fold reduction in neutralising antibody activity against Omicron. A super recent study from the UK indicates that a two-dose regime of the AstraZeneca and the Pfizer/BioNTech vaccine only reach a vaccine efficacy of 6% (sic!) and 34%, respectively if the second dose was more than 6 months ago. It also shows a booster shot can bring the VE against Omicron up to 70-75%, but that's with a fresh booster. It has to be assumed that the protection would again wane relatively quickly, so even with a booster, the effectiveness against Omicron will in practice end up substantially lower than 70%. Yes, all of this is very preliminary and based on small sample sizes when it comes to Omicron, but these numbers are still sobering.

Raw case numbers can be very tricky in a comparison between vaccinated and unvaccinated. For instance, the unvaccinated have to perform more tests, so that the dark figure of undetected infections should be lower among them than among the vaccinated.

I gave you the CDCs data from september when the delta variant was circulating in the US. This is the real world data against delta.

You also managed to find the one outlier study, the other studys on vaccines and delta around the same time show a more modest reduction

The bulk of (second dose) vaccinations in the US came from March through June, so for most people, their vaccinations were still fresh in September. See the chart above (last column) for the waning of the Pfizer vaccine against Delta (with regard to infection). Given a booster rate of around 16% in the U.S., the bulk of the vaccinated in the U.S. right now, in December, will not be 5x less likely to get infected anymore. Their protection is still substantial and far better than if they were unvaxxed, but this '5x' number is not realistic anymore as of today.

Fair enough, guess its time to get everyone their boosters
