Hi Pete,

Just by the way, there were a couple of articles in today's Australian about herd immunity.

We've heard about it since early last year, but it's rarely defined. I'm presuming it means that, if enough people get vaccinated, say 90 %, then the remaining 10 % are a little less likely to get infected.

OR it could mean that some people have a natural immunity.

OR is it a myth ? Created by people reading too many Marvel comics ?

As I understand it, people who have been vaccinated may still be carrying the virus and passing it on to each other, oblivious. So any UNvaccinated person coming into contact with them can catch the virus - and pass it on.

So is any magic 'herd immunity %' target completely futile ? After all, in any given week, most of us bump up, figuratively, against a hundred people, in the street, on the bus, in the supermarket: if just one of them was carrying the virus, an unvaccinated person could contract the virus. If not this week, then next week.

So 99.9 % of people vaccinated may not give the remaining 0.1 % - or 25,000 Australians, 350 thousand Americans - any magic 'immunity' whatsoever.

Just saying :)

Hi Joe

Unfortunately I don't the answers on vaccination and herd immunity. They are out of my areas of knowledge.

Complexity expands to:

A. each person having 2 (rather than one vaccination) of One type of vaccine

OR

B. a vaccination using one type of vaccine. Then a vaccination with another type of vaccine a few weeks apart. Even experts now don't know if B. would be better.

Maybe start your own General Discussion thread on the vaccination-herd issues.

Cheers

Pete

Good questions Joe, as for 90% creating some kind of protection for the other 10%. I think the answer is not a little, but a lot of protection for others. Good doc on YouTube about the Plague in London 1665, made before this pandemic, in a crude way, a similar reaction from people. Also good one is on the Spanish Flu its there as well.

'natural immunity', some people claim they've never got a cold in their life, well I don't know.

What's the general opinion of these elite tennis players and their whinging about the "pain" they suffering. I say they should have called the whole thing off.
