To be clear, I received 2 shots in April 2021. The article doesn't (nor do I ) claim the vaccine's don't provide (temporary) therapeutic value against the virus load.
What it (the science) does say is: Taking the mRNA vaccines do nothing against the spread of the covid-19 virus.
""Pfizer director Rochelle Walensky"" said we see that the vaccinated can contract the infection symptomatically.
But again, you're making a leap that's not there.
Saying that protection against symptomatic protection wanes and suggesting that vaccinated people can still spread it doesn't = "does nothing against the spread"
It may not "stop the spread", but it does "reduce the spread"
This study:
Vaccine effectiveness against SARS-CoV-2 transmission to household contacts during dominance of Delta variant (B.1.617.2), August-September 2021, the Netherlands
...found that vaccination reduced risk of spreading to other household members by 40%, and reduced risk of spreading to non-household members by 63%.
You even stated in your post, therapeutic value against virus load...
vaccinated people also clear the virus faster than unvaccinated.
Lower viral load + swifter clearing of the virus = less likely to transmit in the context of human behavior and interaction.
You're carrying less of it, and you're carrying it for a shorter amount of time.
Who's more likely to spread it (and to more people)? The guy who's carrying the virus around for 10 days, in high viral loads, or the guy who has a lower viral load and clears it in 5 days?
Or a simple mathematical way to address it.
If I encounter 20 people a day, and carry the virus for 10 days, that's 200 potential people I could infect. If clear the virus after 5 days, that's only 100 people I could infect...the 100 people I would've encountered on days 6-10 have been spared having to be around me while infectious.
Horowitz: Harvard researcher finds absolutely no correlation between vax rates and COVID cases globally
I'd be interested in taking a look at the particular research you're talking about.
I've seen similar claims before, and in each case, they've failed to control for lifestyle differences across nations.
For example, several African nations (despite having fewer mitigation measures in place) can boast lower covid numbers despite having very low vaccination rates. However, in many of those countries, people spend a lot more time outdoors rather than indoors. (which we know indoor transmission risks are higher)
The other studies I've seen making those claims have failed to control for comorbidities as well. (IE: a 350lbs smoker, even if vaccinated, is still at a higher risk of symptomatic covid infection than a lean healthy person under 30 who's not vaccinated)
