The problem with herd immunity

A safe prediction:  this will have no effect on Adam Creighton, Andrew Bolt, David Leyonhjelm or any other number of "no lockdown" advocates:
A Spanish study has cast doubt on the feasibility of herd immunity as a way of tackling the coronavirus pandemic.

The study of more than 60,000 people estimates that around just 5% of the Spanish population has developed antibodies, the medical journal the Lancet reported.

Herd immunity is achieved when enough people become immune to a virus to stop its spread.

Around 70% to 90% of a population needs to be immune to protect the uninfected.
And it would seem that the reason why herd immunity may be such a problem for this weird virus:

Herd immunity can be reached either by widespread vaccination or if enough of the population is exposed to an infection and recovers. If enough people are immune to a disease, it is unlikely to keep spreading from person to person. Letting the coronavirus infection run and risking lots of people getting very sick with it is not an option - it would put too many lives in danger.

And currently, there is no vaccine for coronavirus - even though hundreds are in development. The challenge is to make a jab that provides enough protection. It needs to train the body's immune system to learn and remember how to make antibodies that can fight off coronavirus.

Scientists are concerned that this "memory" might be too short-lived though, given the nature of the disease. While some people who catch coronavirus develop protective antibodies, experts do not yet know how long these last.

Common colds are caused by similar viruses and the body's immune response fades quickly to those.

  1. Even standard immunity might be hard to get and maintain with this virus. I mean standard individual immunity. This virus is so well engineered to latch onto the human cells, that the methodology of antibodies neutralising the virus might not be enough for the unprepared body.

    Vaccine propaganda has left the public with this idea that the antibody system is the be all and end all of immunity. Actually its just a small part of the immune system. And the speed at which this virus latches onto, invades and then replicates may wind up outrunning the antibodies that are supposed to latch on to it.

    There is no substitute for preparing in advance for this lurgie with fat soluble vitamins. Then quick action with the powerfully effective HCQ and zinc if you are actually affected by this bioweapon. Treatment needs to come early. As soon as you get the very first tickle in the back of your throat.

  2. Pretty poor bioweapon if a looking for work dude on his laptop in Australia has worked out how to defeat it, Graeme.

  3. Herd Immunity is claptrap because people overestimate the costs here of a the lockdown and do not realise there are benefits.

    You wil have a lockdown. It all depends on w=hat sort of one you have.

    This is a very stupid, illogical, and murderous comment. Its meant to distract people from doing what is necessary to stay safe. Where is the logic here? Reword this as a logical argument so that everyone can laugh at you.

    Matthew 13 [4] And when he sowed, some seeds fell by the way side, and the fowls came and devoured them up:

    Revelation 13 [5] And there was given unto him a mouth speaking great things and blasphemies; and power was given unto him to continue forty and two months.
