Visit or invasion?

It is encouraging to read about vaccines making their way successfully through the early stages of testing. I have been tracking some of the discussion about the SARS-CoV-2 virus in some of the scientific literature. But have to confess that while I can follow the flow of the academic arguments, I find that details ain't sticking in my memory.

I will hardly be alone in having to defer to people with decades of training and experience. However, I have at other stages of my life, seen people benefit from inoculation or vaccination.

More critically, I knew of a family where the parents decided not to allow either of the Salk or Sabin vaccinations against polio to be administered to any of their children. All three caught polio. Although long term there seems to have been no effects, there were many years of misery for the children concerned.

Albert Sabin and Jonas Salk share the glory of all but eradicating polio. But their vaccinations were radically different. Sabin's arrived first to market and was a "dead" virus injected to create immunity. Salk's live-virus oral vaccine shortly followed it.

I think I had the jab. But I certainly remember that a box of sugar cubes became part of the contents of my father's medical bag. Salk's oral vaccine was dripped onto sugar and (almost) every kid took it without question. The small number of dissenters got theirs on a small piece of bread.

I understand that Sabin's jab was considered superior, docs love the needle?, but the ease of administration of a sugar cube won out.

We may be, if we are fortunate, about to see a repeat of the polio vaccine battle. A number of successful vaccines which create the desired antibody creation using a variety of different routes. If successful, that will be good, because a minority for whom a particular vaccine is not appropriate, may have another option.

For the NHS, having a choice of vaccines, if of equal efficacy, should keep the price down as companies compete to get their variant into service.

So for politicians, the challenge will be to avoid dropping options from support when they still look viable. Because in the rush to head off the spread of this virus, the temptation to look for short-cuts is always there.

The traditional "Dr Finlay" approach to community medicine had much to commend it even if a good portion of its success depended on the character of the personal rather than clinical support provided by a trusted local GP. The range of interventions available to them when I was a youngster in the 1940s and 50s was extremely limited by comparison with today.

I remember the excitement of new vaccines and new antibiotics. On one occasion, I had an attack of impetigo, a highly infectious skin condition, which affected my upper lip. This disease killed almost no one and went away of its own accord in about ten days. But I remember my father's excitement at the almost magical effect of Aureomycin, a member of a new class of antibiotics called tetracyclines. Their "trick" was to inhibit the multiplication of bacteria rather than as penicillin which directly attacked them.

As an ointment, it was perfect for my impetigo. It's "magic" effect was, of course, magnified by its using gold as one of its constituents. Hence the "Aureo" prefix. Or so I remember from dinner table discussions. The fact that it was an expensive remedy only seemed to magnify its powers.

Those were simpler days. There wasn't much evidence that GPs spent time extending their skills and knowledge. In today's much more complex world, with a vastly wider range of pharmacological options available, a much greater understanding of the adverse side effects, and the need to consider the interactions of multiple medicines prescribed for more than a single condition in a patient, it's so much more complex.

There was really only one publication that came into the household that gained much consideration. That was MIMS - The Monthly Index of Medical Specialities. It was simply a list of the drugs available for prescription. There were three alphabetical indexes, by drug name, by British Pharmacopoeia name, by disease or condition. And it little bit of commentary at the start about this month's amendments. I suspect this was the only thing father read to keep up to date with what was changing in the medical world. I very rarely saw either the British Medical Journal or the Lancet in his hand. We kids read Pulse, a freebie newspaper for GPs.

MIMS was of some use to the rest of the family too. On a daily basis, packets would be delivered by the postie from drug companies. These samples got slung into a big chest of drawers against the idea that they might prove useful at some future date. Their value seemed to be mostly for self-medication by my siblings and me.

If we thought we were unwell or experiencing a treatable condition, we would consult MIMS. And then rummage around to see if there was a sample that matched our problem. If yes, it was upstairs to consult father. Generally, we would say something like, "Double dose to start and then TID?" (TID - Ter in Die, three times a day - father still prescribed in Latin for names and Greek symbols for quantities). After a brief examination of the medicine, not the patient, he would peer over his specs and generally respond with, "Won't do you any harm".

Today we have central bodies to advise doctors on prescribing. And active monitoring of outcomes.

Choosing from multiple vaccines, as seems not unlikely, will be yet another decision the docs will have to make. But at least there are likely to be solutions available.

I wrote earlier in my diary about our failure to find a vaccine to control the virus clan that causes the common cold even after decades of research. And hung my pessimism about the prospects for a successful SARS-CoV-2 vaccine out to view.

Perhaps today's a day when I should crank up my optimism a notch or two. Although my autumn flu etcetera jabs may require more arms to be punctured in future years. I suspect we shall need at least an annual kick up the rear for our immune systems to continue to be safe from this rotten bug.

As if my cup cannot be already filled up by my pharma-led lifting of mood, my political world will experience a boost today as well.

Boris Johnson is here to help the Independence campaign by reminding us that "London knows best".

Seems he may be visiting the military, as I predicted to my spouse a few days ago, on a visit to Moray.

But then maybe not as he has not done the courtesy of telling the Scottish Government anything about his plans for the day.

Business as usual.

Russia et al

After yesterday's publication of a Westminster report into foreign state meddling in UK democratic decisions, my mind turns to the issue of leadership. Perhaps the fundamental failing identified, and I am assuming that the Parliamentary Committee had access to information that underpinned their conclusions but which is not necessarily shared with us, lay with the Security Service (MI5) and the Secret Intelligence Service (MI6).

The first thing on MI6's web pages is the statement that "We work overseas to help make the UK a safer and more prosperous place". There is much worth a read (https://sis.gov.uk/) but what stands out is their statement that "Everything we do is tasked and authorised by senior government ministers".

Buried at little deeper on MI5's web site (https://www.mi5.gov.uk/) it says, "we formulate our own set of plans and priorities, which the Home Secretary approves."

But there is also GCHQ who on its web site (https://www.gchq.…

While I am pretty confident that we are far from being on a majority in our household, I am also sure that we are not unduly exceptional. We sit down to lunch each day at 1230 so that we can simultaneously masticate and educate. The first refuelling the body. The latter refuelling the intellect.

And the source of brain food? The daily press conference on the pandemic from the Government. The traditional being from fridge and food cupboard.

It's a bit like the family sitting around the radio 75 plus years ago to hear news of the battles against the nazis. Today is remarkably similar. Not a single front of battle but many. Not just fought by those on the front line, but supported by the actions of those on the home front.

Even more than then, the home front is a critical part of the front line. Each citizen's actions, or inaction, directly contributing to or hindering our ability to eliminate COVID-19 from our country.

For me, with an interest in DNA as a tool in my family histo…

Tome for a new keybiard

Today is the one hundred and eighth daily episode of my reports from an 8th decader's lockdown.

For a mathematician, 108 is a "good" number. Having three digits just locks into parts of the brain that tune into threes. And at a glance, it is a number that is divisible by three. Why, at a glance? Because if you add up the digits one, zero and eight, the answer is nine. Any number whose digits add up to a number that divides by three is itself divisible by three.

If after the first add, you have answer bigger than nine, add the digits together and keep doing that until you have a single digit. This is a digit sum.

If the final digit is a nine, then the original number will be divisible by three and by nine. If it's a six, then it's divisible by two and by three. And finally, if it's a three, then it is an odd number which is divisible by three.

I am far from sure, but my memory is trying to persuade me that I was taught this at school. I am certain about the ru…
