RE: They have also jabbed over 300 million people, which contributes to the antibody survey.
India has 1.3 billion people, arguably equal to China’s population.
If the article is correct, 2/3 of 1.3 billion is approximately 850 million people who have the antibodies.
Even if 300 million got their antibodies from the vaccines, that leaves 550 million unvaccinated people ( more than all of the USA, Canada and Mexico combined ) with antibodies.
The rest were probably already infected but did not know it or recovered from Covid.
Remember INDIA is where the Delta Variant was discovered.
“Even if 300 million got their antibodies from the vaccines, that leaves 550 million unvaccinated people ( more than all of the USA, Canada and Mexico combined ) with antibodies.”
This seems correct.
