people continue to argue that the vax is useless because it does not stop ALL transmission.
I don’t see anyone saying it’s useless just that if vaccinated people can still contract transmit the virus, it makes little sense to mandate it for hcps. It’s doing a great job of reducing serious illness/hospitalisation for the individual who has it but that’s not much use to the person they’re caring for.
You can't pass it on if you haven't got it. What's the likelihood of actually catching it reduced by if you're vaccinated? Between 63 and 91% isn't it? Depending on which (reputable) study you read.
but here's some (reputable) facts about transmission from vaccinated people:
"People who are fully vaccinated against covid-19 are far less likely to infect others, despite the arrival of the delta variant, several studies show. The findings refute the idea, which has become common in some circles, that vaccines no longer do much to prevent the spread of the coronavirus.
“They absolutely do reduce transmission,” says Christopher Byron Brooke at the University of Illinois at Urbana-Champaign. “Vaccinated people do transmit the virus in some cases, but the data are super crystal-clear that the risk of transmission for a vaccinated individual is much, much lower than for an unvaccinated individual.”
A recent study found that vaccinated people infected with the delta variant are 63 per cent less likely to infect people who are unvaccinated.
This is only slightly lower than with the alpha variant, says Brechje de Gier at the National Institute for Public Health and the Environment in the Netherlands, who led the study. Her team had previously found that vaccinated people infected with alpha were 73 per cent less likely to infect unvaccinated people.
What is important to realise, de Gier says, is that the full effect of vaccines on reducing transmission is even higher than 63 per cent, because most vaccinated people don’t become infected in the first place.
De Gier and her team used data from the Netherlands’ contact tracing system to work out the so-called secondary attack rate – the proportion of contacts infected by positive cases. They then worked out how much this was reduced by vaccination, adjusting for factors such as age."
