Vin,
That's a Study about a Lab Dish. Come on.
We have plenty of People infected daily, it's a simple question "Is this the 1st you were aware you have been infected?
They can tell us every 5 minutes about who wasn't jabbed.
A new study published Thursday in Nature adds new detail about the dominant variant, analyzing how well Delta, in a lab dish, was able to evade monoclonal antibody drugs such as bamlamivimab and natural antibodies made in our bodies after infection or vaccination. Looking at both kinds of antibodies in blood drawn from 162 patients and how they reacted to Delta, researchers from the Institut Pasteur in France found lower protection against the variant than against three other variants also notable for how easily they spread from person to person.
The findings underscore the effectiveness of vaccines against the Delta variant if people get the recommended two doses. They also highlight the added immunity a single dose of vaccine provides people previously infected with another Covid variant.
