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.

De Gier says they cannot calculate the full reduction in transmission due to vaccination, because they don’t know exactly how much vaccination reduces the risk of infection. But even assuming vaccination only halves the risk of infection, this would still imply that vaccines reduce transmission by more than 80 per cent overall.

I am going for my first shot today. I must admit - I am nervous. I see on Dischem's site they recommend 6 months before getting the vaccine. So not really sure what to think. Really hope I don't get blood clots.

I hope it all goes swimmingly for you, and that you don't have any side effects. 🤗

Just an interest sake thing, this is reduction in chance of being symptomatic based on what vaccine, Pfizer and Moderna got grouped together but Moderna is a little bit more extreme. Note this is vs non-vaccinated being symptomatic, and it's reduction in chance, not chance to be.

Not South Africa specific, but would say worldwide fine, so can go in this thread. Above is why Austria is changing to you need another vaccine shot after J&J and J&J doesn't count as fully vaccinated past 3 Jan (got mine a few weeks ago, J&J first in June, and just had Pfizer as second).

You should be fine, I've had three shots of Pfizer now and other than becoming slightly magnetic I'm perfectly fine.
