Vaccination


The big difference between this pandemic and the Spanish Influenza has been effective vaccination. 

In 1931 German Physicists, Ernst Ruska and Max Knoll, developed the first electron microscope, at the University of Berlin, and, in 1935, a virion was photographed for the first time. Yet, it was not until 1955 that the full structure of the tobacco mosaic virus was first elucidated, by the ground-breaking x-ray crystallographer, Rosalind Franklin, who's work also helped reveal the double helix structure of DNA.

From that time on, cell-biology and bio-technology moved forward in leaps and bounds. So that in 2020 several dozen independent teams around the world set to work. The process of highly specific vaccine development, based on a detailed molecular map of the virus, that two decades ago took decades to accomplish, was foreshortened to a few months. 

Thus, ten, tested, safe and efficacious, vaccines against the virus, employing a range of technologies, have already been deployed in many countries. And many of these teams are continuing to work against the rise of the inevitable virus variants:

COVID-19 vaccines, and the technologies employed, as at January 2022 

  1. Pfizer BioNTech (BNT162b2) mRNA vaccine*
  2. Moderna (mRNA-1273) vaccine*
  3. Oxford/AstraZeneca (ChAdOx1-S) [recombinant] (viral vector) vaccine*
  4. Janssen (J&J) Ad26.COV2.S (viral vector) vaccine*
  5. Sputnik V (viral vector) vaccine
  6. Novavax (NVX-CoV2373) (subunit) vaccine*
  7. Sinovac-CoronaVac (inactivated virus) vaccine
  8. Sinopharm (inactivated virus) vaccine
  9. Bharat Biotech BBV152 COVAXIN (inactivated virus) vaccine
  10. Convidecia (AD5-nCOV) (viral vector) vaccine (WHO approval pending stage 3 trials)

  * Available in Australia

Europe 2022 - Part 2

 

 

 

In July and August 2022 Wendy and I travelled to Europe and to the United Kingdom (no longer in Europe - at least politically).

This, our first European trip since the Covid-19 pandemic, began in Berlin to visit my daughter Emily, her Partner Guido, and their children, Leander and Tilda, our grandchildren there.

Part 1 of this report touched on places in Germany then on a Baltic Cruise, landing in: Denmark, Finland, Estonia, Latvia, Sweden and the Netherlands. Read more...

Now, Part 2 takes place in northern France. Part 3, yet to come, takes place in England and Scotland.

Fiction, Recollections & News

Should we be worried?

 

 

 

"Yesterday, as I stood at my last stop on the campaign trail, I'll never be doing a rally again, can you believe it? I think we've done 900 rallies approximately from. Can you imagine? 900, 901 or something. A lot of rallies. And it was sad. Everybody was sad..."
"They said that many people have told me that God spared my life for a reason. And that reason was to save our country and to restore America to greatness. And now we are going to fulfill that mission together..."
"I will govern by a simple motto: Promises made, promises kept. We're going to keep our promises. Nothing will stop me from keeping my word to you, the people. We will make America safe, strong, prosperous, powerful, and free again..."
"Success is going to bring us together and we are going to start by all putting America first.
"We have to put our country first for at least a period of time. We have to fix it. Because together we can truly make America great again for all Americans. So I want to just tell you what a great honor this is. I want to thank you. I will not let you down. America's future will be bigger, better, bolder, richer, safer and stronger than it has ever been before. God bless you and God bless America. Thank you very much. Thank you very much."

 

Presumably, 50-year-old volunteer fire chief; father of young daughters; and a committed church-going Christian: Corey Comperatore, lost his life as a part of God's plan, along with fellow rally goers: David Dutch and James Copenhaver, who also stopped bullets; Dutch critically.

 Nevertheless, Trump certainly loved his rallies. 

 The most talked about moment in the The Harris-Trump debate was when Harris mocked his rallies and Trump responded by asserting that Haitian immigrants in Springfield were eating the residents' pets. 

 

"At the ABC News presidential debate, former President Trump went on a tear accusing Haitian migrants in Springfield, Ohio, of eating pets."

 

 

This was the real Springfield, as opposed to the Simpsons' fictional one.  

  

This man is about to return as 'Leader of the Free World'.

Yet, he saw no warning signals before repeating the Springfield nonsense.  It reminded me of his suggestion, also picked up on Social Media, that Covid-19, might be overcome with household disinfectant.

 

President Trump claims injecting people with disinfectant could treat coronavirus

 

 

And his claim that the F-35 stealth fighter was actually invisible.

 

In a Thanksgiving speech to the US coast guard, President Donald Trump hails the F-35 fighter jet, calling it an "invisible" plane that they "enemy cannot see".

 

 

We already knew that his grasp of American, let alone World, history was woefully inadequate for someone holding, high office.  And this gets to the heart of the matter: he's an ignoramus.

I don't mean he's stupid but he's lacking in the most basic knowledge of how the world actually is. 

No doubt the occasional cat or dog does get eaten by a homeless person but ravenous immigrants, en masse, falling on the pets of Springfield?

The average twelve year old could tell him that this story is unlikely to be true. That same child could tell him that a stealth-jet is not actually invisible (to the naked eye); and that injecting disinfectant; or exposing yourself to radiation, sufficiently energetic to kill a virus infecting you, would very likely kill you too. 

But his ignorance is legendary:

 

Donald Trump often discusses history, and he has a unique way of talking about it.

 

Yet, on several cruises that we have been on with older Americans: "What do you think of Donald Trump" is a standard question at dinner. A few don't like him but for the great majority: 'The Don' can do no wrong. All the negative things said about him are just 'fake news'.  They are 'welded on' regardless.

Now this majority of Americans have got what they wished for - manifest destiny? As bob Dylan sang: With God on Our Side.

I'm worried.

We all die of something.

After 70 it's less likely to be as a result of risky behaviour or suicide and more likely to be heart disease followed by a stroke or cancer. Unfortunately as we age, like a horse in a race coming up from behind, dementia begins to take a larger toll and pulmonary disease sees off many of the remainder. Heart failure is probably the least troublesome choice, if you had one, or suicide.

In 2020 COVID-19 has become a significant killer overseas but in Australia less than a thousand died and the risk from influenza, pneumonia and lower respiratory conditions had also fallen as there was less respiratory infection due to pandemic precautions and increased influenza immunisation. So overall, in Australia in 2020, deaths were below the annual norm.  Yet 2021 will bring a new story and we've already had a new COVID-19 hotspot closing borders again right before Christmas*.

So what will kill me?

Some years back, in October 2016, at the age of 71, my aorta began to show it's age and I dropped into the repair shop where a new heart valve - a pericardial bio-prosthesis - was fitted. See The Meaning of Death elsewhere on this website. This has reduced my chances of heart failure so now I need to fear cancer; and later, dementia.  

More fun and games.
