Being double jabbed doesn't make you immortal, but it does reduce risks.
A double jabbed 80 year old is still not going to be as resilient as a healthy 30 year old, that is beyond the capacity of vaccines.
The emergence of Delta variant has reduced the effectiveness of fully vaccinated people being less likely to spread Covid, but it hasn't stopped it being the case.
It is an area that needs further investigation, and a higher profile so it is clear the difference between being vaxed and unvaxed.

Vaccinated people are less likely to spread Covid, new research findsOct. 2, 2021, 6:39 AM AESTBy Akshay Syal, MD
People who are vaccinated against Covid-19 are less likely to spread the virus even if they become infected, a new study finds, adding to a growing body of evidence that vaccines can reduce transmission of the delta variant.
Both vaccines reduced transmission, although they were more effective against the alpha variant compared to the delta variant. When infected with the delta variant, a given contact was 65 percent less likely to test positive if the person from whom the exposure occurred was fully vaccinated with two doses of the Pfizer vaccine. With AstraZeneca, a given contact was 36 percent less likely to test positive if the person from whom the exposure occurred was fully vaccinated.
The risk of transmission from a breakthrough infection was much higher if someone had received just one dose of either vaccine.
The study was posted online Thursday and hasn’t yet been peer reviewed. But scientists not associated with the research said the findings were credible.
