Herd immunity would not be achieved even at 100% vaccination rates with AstraZeneca — the disease would still spread. By Stefano Rebaudo.

Crucial points:

Vaccine optimism has peaked. …

If the UK’s estimates are correct, “herd immunity will require 90% or more inoculation with mRNA vaccines,” as adenovirus vaccines like AstraZeneca are less effective.

For countries with a greater reliance on vaccines like AstraZeneca, “herd immunity would not even be achieved at 100% vaccination rates — even with the entire population vaccinated, the disease would still spread,” they argue.

I couldn’t find a link to the text, so either this was on a private financial news service only (namely Live Markets, by Reuters), or the news is being censored by the search engines. However, the content is accurate to judge by other credible sources.

Too many people still have a simplistic notion about the vaccines. It is critical to note that vaccinated people can both catch covid and spread covid to others — just at reduced rates.

The protection rates quoted for the vaccines are the percentage reductions in your chances of requiring hospitalization should you catch covid. Not what you’d expect, eh?
