Had my Pfizer booster today, chap in the waiting lounge was telling us how all these injection had cured his needle phobia, at this point another fellow told us of his first injection at school, they told them the week before that they would have one and he asked his mum what an injection was. She told him that they put some special liquid on a needle and stuck it into you arm to stop you getting ill. Trouble was he had only ever seen knitting needles and was scared blankless! Come the day he saw all the kids in front of him in the queue come out crying which made him feel no better. Once he was inside and saw the tiny needle he laughed in relief and has never been scared of needles since.
The IM injection sounds unpleasant, but the needle is such a fine gauge that it really isn't. Muscle is not very sensitive, so once it gets through the skin and subcutaneous tissue, should be fine. The needle used for blood taking is a thicker one and you feel it more, in my opinion.
That's true, in my experience
I had the Moderna booster last week along with the flu jab, one in each arm, had no issues whatsoever
Needles have a coloured plastic piece where they connect to the syringe. This denotes the width of the channel in the needle. This is important because some medicines that are injected are thick, and sometimes blood drawn can be damaged if the needle is too thin.
The normal blood sample needle is a green needle, which has a 21G thickness. There is another commonly used thinner needle, a blue needle, with a 23G thickness. This is sometimes used for blood sample in kids or in tricky veins. IM injection usually uses the blue needle, or even one size thinner. All of the needles are very sharp, which helps. The main unpleasantness is trying to push it through the skin. If it slips in like a hot knife through butter, much less pain. A good injector should usually be able to inject basically without any pain. A good decisive action is best, hesitation or fumbling is not good.
If you are unfortunate enough to be in an accident or other situation where you need fluid resuscitation with large volumes of (often rather gloopy) fluid administered fast, then a needle or cannula that looks more like a knitting needle will be used. Flow rates are related to the 4th power of the radius of a pipe or tube, so getting in a larger needle/cannula increases flow rate a huge amount especially something gloppy like blood or colloid.

It is not supposition to look at cases and death rates through last year until now. There is simply a different time dynamic between the UK and some other large European countries. I am not anti-AZ vaccine, I have frequently said that it is a good vaccine and has a role. But it is not a matter of opinion that it is less effective than the mRNAs. Sorry if that displeases you, but that is how it is. I also believe, as do others in industry, that AZ was not the right partner for Oxford, and a partner with a track record of vaccine development and scalable manufacturing capacity would have been better.
Pascal Soriot has established his own track record of saying stuff that was later shown to be incorrect, starting with the timelines and quantities expected for the AZ vaccine. Credence is earned. He admitted yesterday that there is no evidence at all of what he says and the response in social media within the UK medical community has been in line with mine. If you have a theory about how a markedly superior effect on antibodies by mRNAs over adenovirus vectors is overturned to become a superior effect on T-cells by the adenovirus vectors, which is essentially what he was waffling about, I would be happy to see it. The conventional understanding of the human immune response to vaccines can then be rewritten.
I don't blame Soriot for puffing up his product, just as they announce they intend to make some money from it, but he was not talking science he was doing PR. I thought you would have spotted that.

Decided to buy some antibody tests (not convinced they are that sensitive but anyway the pictures paint the gest of what they indicate) :-
Click on pictures for bigger ones.
Late Middle aged person, 5 month post 2 x AZ, soon to be boosted(going for pfizer as the better safety profile) :-
Young person, 3 months post 2 x Pfizer :-
Old way past retirement age person, 2 weeks post Pfizer Boost , 2 AZ originally :-
Happy moving into December and changing things up, at the least the oldest has the strongest line.

Are you saying that as a surprise ?
I would be surprised if it takes 4 years for the vast amount of the population to catch covid at least once(whether they know about it or not).
Time will tell how this will unfold and anyone telling you they know are plain lying

You do bad mouth AZ at every opportunity, did they turn you down for a job or something 🤣🙃😅😀😱

You have been reading Pagels twitter page again, said not to. I heard you cant beat going to 'alot' of shops once you have shown symptoms whilst being so careful. Think that might help to get it around.
Prof. Christina Pagel on Twitter: "Secondly masks: the first symptoms were so innocuous it was only obvious later what they were. I was 100% convinced we didn't have Covid cos we'd been so careful. The weekend before symptoms and 1st day of, we were in *a lot* of shops. 3/8" / Twitter
Its amazing what people post and think its okay to and from people who should know better.

I know. They should have accepted it. Soriot was CEO then, but, as I said here earlier, overplayed his hand and Pfizer got fed up and walked.
While getting a cannula put in yesterday, for a CT heart scan, the nurse explained to the young student nurse how to insert and remove it, to prevent/reduce any bruising.
She said " when taking the cannula out ,immediately exert pressure on the exit wound and press hard for at least 20 seconds then check, especially if the patient is on any blood thinning meds ".
It worked very well , I never felt a thing going in or out and not a bruise in site, happy days.
I just hope the results are as good

She went on to explain to the student that if not pressed hard enough the blood will leak under the skin leaving an unnecessary bruise, for the sake of a few more seconds.
