Reply to comment by JurassicCotyledon in A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga

Is it not true that the pfizer vaccine doesnt reduce transmission?

From what I’ve read, not effectively. That’s why I’m wondering if anyone has specific data on that, and isolated to identify the transmission rate reduction incurred purely by the vaccine, versus from previous infection.

Pfizer didn’t even test for transmission blocking during their trial prior to the mass vaccine rollout.

They were actually pretty effective at preventing symptomatic infections prior to Delta and Omicron.

Does being asymptomatic mean you cannot transmit the virus to others?

And they will continue to mutate and evade the narrow and short lasting immunity offered by these vaccines.

How would you ethically test for the effectiveness of a vaccine in blocking transmission?

Animal models.

Double blind placebo controlled trial involving people in roles involving frequent contact.

Similar model for phase 3 but using larger groups in broader community.

The important thing is to have put forth an effort to do so, and to collect this data in the long term without muddying the water by unblinding the control groups. This has not been the case here from what I’ve seen. It’s not going to be perfect, obviously in times of emergency especially, but that doesn’t change the facts at hand.

But on the subject of ethics, would it be ethical to tell people to get vaccinated with a brand new technology, and claim “you’re doing your part” by reducing transmission, if you have no data to support that claim to begin with?

It seems to me like a bit of a no-brainer that someone that has COVID and doesn't even realize it because they have no symptoms what-so-ever (vaccinated) would not spread the virus nearly as much as someone that is half dead with the virus running rampant through their system and they are coughing up a lung, spewing particles everywhere they go (unvaccinated). Sure there are exceptional cases, but I'm talking on a broad scale.

I'm no expert though, just going on common sense.

I'm triple-vaxxed (in my 40s) and I'm pretty sure I've had COVID at some point and didn't even know it. My elderly mom got it too and barely missed a beat (also vaccinated 3 or 4 times). She lives with my dad (nearly 80) and he did not catch it. I understand this is not scientific data, but it speaks to me about the effectiveness of the vaccines and their ability to reduce transmission.
