Aussie Government: Blood Clotting Case Likely Linked to Astra-Zeneca Covid Vaccine

Guest essay by Eric Worrall

Australia’s Deputy Chief Medical Officer Professor Michael Kidd has stated that a blood clotting problem which led to a vaccine recipient being hospitalised was likely linked to the Astra-Zeneca Covid-19 Vaccine. Note the USA mostly sources vaccines from Johnson and Johnson and Pfizer.

Melbourne blood-clotting case ‘likely’ linked to AstraZeneca vaccine, Deputy CMO says

By Michael Doyle

Australia’s Deputy Chief Medical Officer says it is “likely” there is a link between the AstraZeneca vaccine and a Melbourne man being hospitalised with blood clots.

“Given how consist of the clinical features are in this case, with some similar cases which have been seen overseas, it is likely that this case, which is reported, is related to the vaccine,” he said.

He said investigations were ongoing.

“The risks of serious side effects remain very low,” Professor Kidd said.

“But safety is paramount, which is why ATAGI and the TGA continue to do due diligence on this case.

It is obviously unsettling to read about cases of adverse reactions, but in my opinion the balance of risk still favours vaccination. The original Covid death rate was around 2% 0.5-1%. Although improved therapeutics have brought the Covid death rate way down, the health risk associated with catching Covid appears to be significantly worse than the risk of a severe adverse reaction to the vaccine.

Correction (EW): h/t Andy – The 2% was based on my incorrect memory of a WHO estimate, but my memory was wrong – the WHO estimated 0.5-1% after taking into consideration an estimate of asymptomatic or mild cases which were not accounted for in original estimates. I’m not sure how good the WHO estimate is, other estimates range from 0.1% to 25%, according to the WHO, so feel free to throw a dart.

The “original” Covid-19 death rate was never around 2%. The problem is, you can’t speak only of death rate without specifying whether you mean case fatality rate or infection fatality rate. Case fatality rate is the ratio of deaths to the number of patients who are so ill they turn up at the hospital as cases. Infection fatality rate is simply the ratio of the numbers who die compared to the numbers who have become infected. Since a lot of people don’t even have symptoms, we can’t even be sure of the true numbers, but even taking the number of positive cases, IFR is estimated to be around 0.2%. And for healthy people under fifty, a lot less. In the view of Dr Yeadon, a young healthy person has more chance of being killed driving to the vaccination centre than dying from Covid-19. The injuries and deaths caused by the vaccine however, are proving to be significant – and that’s only short term.

There is a suspicion that it is not the vaccine but the way it is given out. Normally with an injection in the top of the arm, it is aspirated( pulled lightly out to check if they have gone into a blood vessel which is very dangerous as it should go into the muscle) These covid vaccines are not being aspirated, which means that with tens of millions of injections some will find a blood vessel and go straight into the blood…..

That’s quite interesting, and seems a useful working hypothesis. Is there a reason for the different technique? Do you have a reference?

Ditto.
They stick the needle in and push the plunger.
Always, every time, with every vaccine.

The BBC news had a story 2 nights ago from a hospital in France. A woman had been admitted with serious covid19 infection and was entering intensive care. It turned out she had a month or so previously been offered the AZ vaccine. She refused. She was holding out for the Pfizer vaccine. But she got covid19 before it arrived.

The woman was asked if she thinks she made the wrong decision about refusing the AstraZeneca vaccine. Her reply: “non”. (She might have added – “je ne regret rien”?)

The chance that that woman will fail to survive is in the tens of percent. Somewhat higher than the risk of an AZ blood clot.

She chose ……… poorly.

Multiply this by the millions of people who refuse to get vaccinated.
I cannot figure out if they think they are being brave or something.
Or are they cowards?
Are they too delicate for vaccines?
Or too tough?
I wonder how many refusing vaccination are gonna volunteer to work the covid wards, changing sheets and bed pans, with no PPE…since there is nothing to be concerned about?

My sister, in the UK, had the first dose the other day of this vaccine and has has a severe allergic reaction to it. She will not have the second dose. Don’t blame her, experimental, emergency use approved, vaccines with little testing. What could possibly go wrong?

Britain are rolling out the AZ vaccine at full speed. Covid rates are falling and lockdown is being phased out.

In both the EU and the US, covid infection rates are rising. Lockdowns are on the way back. And both the US and EU are sitting on stocks of tens of millions of vials of the AZ vaccine which they are refusing to use primarily out of political and national prejudice against the U.K.

How many lives are they willing to sacrifice in order to indulge their anglophobic nationalist political agendas? We’ll soon find out.

Britain is considering “freedom passports”, a similar thing in Denmark as I understand. There are some major events coming up in the UK in a few weeks, and “COVID safe freedom passports” are going to be trialled. You will have to have a “smartphone” app. Deaths from “COVID-19” in the UK are not on the rise. Italy tested 18,000 people the other day and they “tested” positive for whatever the PCR CT number wanted to produce.

AstraZeneca has not even filed for an EUA in the US yet.
So I am not sure what you are talking about.
We have three vaccines here, and at this point we are vaccinating about three million a day and rising fast.
We will have enough of the two best ones for everyone, and then some, by the end of May.
It is unlikely we have enough people to jab arms to get it done any faster than it is getting done already.

BTW, I live in Florida, and there are no lockdowns here.
There have not been and will not be any.
No mask mandates either, at least not at the government level.
But almost everyone wears one anyway.
Because most people just want to get this all over with and not be antisocial, nitwitted, or hardheaded about it.
And I think I am not the only one who is acutely aware the Democrats will be so very happy if tens of millions of conservatives refuse to get vaccinated.
Sure would be a shame if it is breaking that way on the numbers of antivaxxers.

The AstraZeneca vaccine will not be an issue for the USA.
The USA has decided to join Europe in its hostility toward AZ based on nationalistic predjudice.
Therefore latest indications are that AstraZeneca will withdraw its application for U.S. approval, emergency or otherwise.
An under-priced drug is offensive to the financial-pharmaceutical community of the US where the idea of low cost medical care is fundamentally intolerable.
So anti-vaxxers all – pop a champagne bottle to celebrate, preferably in a room with several hundred of you together.
B.1.1.7 is another British export which does not require FDA approval – enjoy!

Sorry for the late reply. In the back of my mind, I wonder if taking low-dose aspirin after receiving the vaccine would prevent blood clots. About 7 years ago, they accidentally found that I had two large blood clots in my vein coming from my right leg. After a one-year regimen of blood thinner, the hematologist recommended that I take low-dose aspirin for the rest of my life. He had no idea what caused the blood clots.

I don’t like the term “anti-vaxxers” — it’s another word that causes division among us. Personally, I take every immunization they offer me, because I feel like (not scientific) it increases my overall immunity. And I am continuing on as a participant in the Phase-3 Moderna vaccine study. I found out that I received the real vaccine in Aug/Sep 2020.

Good points. Perhaps a few aspirins should be given with each AZ jab?

Why?
There is zero evidence of any increase risk of blood clotting.

The vaccine is free here.
All of them.
Trump paid for hundreds of millions of doses from each of several companies long before any got the clinical trails underway.
The US gave AstraZeneca $1.2 billion in funding.

That is the largest reason we have hundreds of millions of doses made to date, with much more coming every week.
I have not heard anyone here bashing anything.
How many billion did GB put up in advance, knowing it could be wasted if the drugs did not work? Serious question, I do not know.
But I know what you are saying is BS.
The J and J one is made by Janssen, a Belgium company.
The US also funded Sanofi (French) and GSK (British) to the tune of $2.1 billion.

Many do not want the J and J one, because it is less effective.
But some only want that one, because it is based on an older approach.
No one is even talking about or caring about one that is not approved yet.
In fact there are several that will possibly apply for an EUA in the coming weeks and months.

What is up with this USA bashing?
No one here gives a tiny rats ass where the stuff comes from, only that it works.

The blood clotting risk with the AZ vaccine is still unproven. ~18M million AZ jabs done in the UK and 3 or 4 dead, no higher than normal. Compare that with the statistically ~35 lives saved per million jabs per week.
Macron is beyond stupid, France is already a vaccine skeptical country (see this comparison between countries) and he throws petrol on the fire to reduce the take up even further.
