Penicillin is not Avastin, but it could have been...

My book - The smallest Manhattan Project  - is about us , all 10 billion of us , here today or years dead, whose lives have been improved by the advent of inexpensive penicillin.

In a sense, this book is a rarity : one written from the patient's eye view of how that drug came to be ; a welcome change after decades of endless books exclusively devoted to how penicillin looked to the people who discovered and developed it.

Penicillin is frequently called the Miracle Drug but few consider that its biggest medical miracle was really in fact its cost, or rather 'lack of cost'.

Because the diseases that penicillin treats are contagious,  patients too poor to afford a cure remains a reservoir of the most virulent strains, waiting to infect the rest of us.

There actually were methods of preventing much of these diseases before the development of penicillin : they included the ready availability of good jobs, good food, cleaner and bigger homes, greater social respect.

Baring that, only the worldwide availability of a drug that would cure those diseases once they started up, at a price that almost all could readily afford , could reduce these diseases from being endemic or epidemic to just names in a dusty medical textbook.

That is why I can say, with absolute assurance, that even those of us who have never had a single treatment of beta-lactam (penicillin family) antibiotics are in better health today because the grandparent of them all, Penicillin G , is water cheap - literally a lifesaver "too cheap to meter" .

But it almost didn't happen , we almost lost "inexpensive penicillin".

We almost got an expensively patented synthetic drug more akin to Avastin and all those other $100,000 a year plus medications.

"The smallest Manhattan Project" is the story of a doctor ( himself slowly dying of another unrelated disease) who sacrificed his own health to see penicillin from the patient's point of view.

His name should be honoured for all time.

This, despite the fact that he did not discover penicillin and then neglect it (Fleming) nor did he start its re-discovery and eventual development, albeit while pursuing a pathway that nearly killed off that development (Florey).

Dr Martin Henry Dawson, for that was his name, merely said penicillin should be made available - now! - for every single patient whose life could be saved by it , even during the height of a Total War .

Nay, he went much, much further.

Dawson in fact said all should have access to life-saving penicillin, particularly in the middle of a Total War.

That was because that war was supposedly being fought against one opponent in particular, solely because that opponent's core philosophy said that 'some lives are more worthy than others'.

How could we continue to conduct that war with any moral vigour when our own medical establishment was 'me-tooing' Hitler's doctors ?

Now the mantra 'Penicillin for all who needed it regardless of their income level or skin colour' in the mid-1940s meant its mass production, given the vast amount of infectious disease endemic in those years.

And mass production has its myriad ways of driving production costs down, down , down --- as happily happened in the case of Penicillin G in almost textbook manner.

'Penicillin for all' quickly became 'inexpensive penicillin for all' and once that happened, penicillin began to work almost like the way a good public health vaccine program should work : the treatment of the many ultimately offering 'herd protection' to all the rest of us, free of charge.

Insulin is another drug frequently called a miracle drug.

But the sad fact is that it is far more common today than it was beforeinsulin was discovered, for a variety of reasons.

By contrast, the names of all those bacterial household scourges that so terrified our mothers and grandmothers are not even known to most of us under the age of 50, and most doctors practising today have never seen a case of them.

And that is just the sort of modern day miracle that Dawson's mantra of 'penicillin for all' can produce.

For the complex truth is that our choice of medical ethics has economic consequences and these in turn feedback and have medical consequences.

The case of what the mantra of 'penicillin for all' ultimately led to should be taught in every health economics and health ethics oriented university department for just those very reasons....

Florey vs Dawson : penicillin to be perfect & a war medicine OR an imperfect but universal medicine ?

patricia (Patty) Malone penicillin breakthrough september 1943
Baby Patty Malone helped the whole world discover penicillin 
As should be well known, penicillin-the-molecule and penicillin-the-lifesaver were discovered September 1943 by the whole world, (not in September 1928 by Alexander Fleming) while natural-penicillin-the-universal-livesaver was invented on October 16th 1940 by Henry Dawson.


Penicillin-the-molecule was ignored in June 1929, firstly by Alexander Fleming himself and secondly by the world.

This was because Fleming on that date indirectly denied any possibility of penicillin ever becoming a lifesaver, ie a systemic ( spread through the blood system) medication.

As a result, Fleming - and the world - yawned.

Contrast this with Banting team's excited, animated, passionate announcement --- at a Boxing Day medical conference just a few years earlier  -- that it was  just two weeks away from injecting insulin-the-lifesaver into a dying patient.

(What a Boxing Day present for millions of diabetics and their familes !)

You can just bet that insulin-the-lifesaver and insulin-the-molecule were discovered together, by the entire world, at that moment.

What about Howard Florey then ? Didn't he play some role in penicillin ?

Yes, some role.

But Florey ,along with Fleming, and along with the British and American governments together with the leading firms in the pharmaceutical world, was convinced that penicillin first must be perfected (100% pure, industry-made, probably synthetic, tested-onto-death) before being used on humans .

 And even then 'humans'  really meant 1A military personnel only, at least during the war.

In addition, they all only saw penicillin as an useful supplement to the existing sulfa drugs - mostly for use in sulfa-resistant staph infections.

Truly a perfectionist and limited vision of wartime penicillin.

One can only begin to imagine the high prices that would be charged governments and patients for such perfect material.

Chain deserved less credit for his chemistry and more for his pushiness , in forwarding the penicillin story to a happy conclusion...


By way of total contrast, only five weeks after learning of penicillin's lifesaving potential (and here Florey and above all Chain deserve the credit) , Dawson was injecting life-saving penicillin into 4F civilians ( Negroes ! Jews !) dying from a strep infection (SBE) , using imperfect , impure, hospital-made, natural, penicillin made by slimey molds.

Yes, like Banting's first insulin injections, Dawson's first penicillin injections 'stung like a bee', from natural impurities still in it. The stings, in both cases, did no permanent (or even temporary) harm.

To Dawson (and to Banting, his model) saving dying patients today with imperfect, impure medication was preferable to letting them die so we can maybe save dying patients, years from now, with a perfected pure medication.

These clashing visions of penicillin ran throughout the war with Florey's vision overwhelming dominant until Dawson's success with -stolen - government issue penicillin on SBE patients inspired another local doctor (Dante Colitti) to jump over the traces for his dying patient as well.

The resulting  heart-stirring story of baby Patty Malone ( late August - early September 1943) broke the media floodgates and the entire civilian world began to "ACT UP" and demand Dawson-style penicillin - now !

By 1944, the Allied governments, dragging the still reluctant Big Pharma firms along with them, had caved.

Semi-purifed, semi-perfect - CHEAP- natural penicillin was being mass produced and being made available for all, as fast as that was humanly possible.

And not just Allied civilians as well as Allied military personnel , but for Axis POWs , Neutral nation civilians and ultimately even Axis civilians.

Canadians Banting and Dawson and Canadian Medicare : there is a pattern here :  a strong belief in medical care that is universal in theory as to who is permitted to receive it (everyone, anywhere) and universal in practise (as a result of being very inexpensive).

But it wasn't something simply discovered and instantly received with acclaim by everyone - as science historians want you to believe how science works : as a totally bloodless affair.

 Instead, it was invented by some humans and contested fiercely by some other humans until finally most humans accepted it.

Invented by people like Banting, Dawson and Douglas ...
