Coronavirus (Covid-19)

2 people suffer allergic reaction following Pfizer Covid-19 vaccine in the UK

Tanutam Thawan



2 UK health care workers who received the new Pfizer/BioNTech vaccine on Tuesday, the first group of people to receive the approved vaccine against Covid-19 in the western world, have suffered adverse reactions. The 2 cases were out of the 1000s who have already received the new vaccine.

The National Health Service issued a warning yesterday that people “with a history of a significant allergic reaction to a vaccine, medicine or food” should not be vaccinated with the recently approved vaccine. Both of the medical workers experienced anaphylactoid reactions but had a “strong past history of allergic reactions”. Both have since recovered after treatment for their allergic reaction.

Adding to the warning against giving the Pfizer/BioNTech shot to people with “a history of significant allergic reactions”, the UK regulatory agency says the drug should only be administered “in facilities where resuscitation measures are available.”

“As is common with new vaccines the MHRA (UK drug regulator) have advised on a precautionary basis that people with a significant history of allergic reactions do not receive this vaccination after two people with a history of significant allergic reactions responded adversely yesterday.”

Britain has became the first western nation to start mass-vaccination against Covid-19. Health care workers administered the first doses of the Pfizer/BioNTech vaccine to thousands of people across England, Wales, Scotland and Northern Ireland.

The Pfizer vaccine was approved by Britain’s independent pharmaceutical regulator for “emergency use based on preliminary data from Phase 3 human trials that showed it to be safe and highly effective”.

Pfizer, along with US drugmaker Moderna, and Britain’s Oxford University working with AstraZeneca, are currently waiting for Emergency Use Authorisation for their vaccines from the US Food and Drug Administration.

The first 800,000 doses of the Pfizer/BioNTech formula are going to people over 80 years of age who are already hospitalised or receiving outpatient services, as well as nursing home staff. NHS workers are also at the front of the queue. The approved vaccine will also be made available at individual vaccination sites once the high-risk patients receive their inoculations.

The UK plans for the NHS to wind-up its vaccination program in a bid to treat some 25 million of the most vulnerable citizens.

British health officials have made it clear the vaccine will not be mandatory.

    Extraordinary that they weren’t aware of this from trials before approval was given ….. or maybe not.

    Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you’re allergic to, such as peanuts or bee stings and foreign proteins .And now Covid -19 vaccine.Yeah it is when you hastily approve medicine.

    Exactly, B.T.

    There should be absolutely no excuse at all for this happening if the vaccine had been properly tested instead of being rushed through for political expediency, nothing more.

    The UK regulatory agency now saying that the drug should only be administered “in facilities where resuscitation measures are available” will completely change the planned distribution and roll out (assuming there actually was a “plan”) since many GPs will now not be in a position to administer the vaccine (which some have already said they do not want to do, for a variety of reasons). nor will many care homes.

    What a complete SNAFU

      Rushed through for political expediency? I’m the first to criticise the UK government’s handling of the crisis but in this case they’re rightly getting on with the business of saving lives.

      Whatever nonsense some people choose to believe the vaccine works, so why would you delay the successful vaccination of 39,998 people because 2 people have an unpleasant but non-lethal reaction, the same reaction which can happen to some with an aspirin or a peanut.

      Wrong also about resuscitation measures, all UK GPs have them as a matter of course, it would be pretty weird if they didn’t.

      However Malc Thai is quite right when he says they should have been asked, still no harm done and lesson learnt for UK and the rest of the world.

        “Why would you delay, etc” ?

        Because it wasn’t tested on those who were shielding or in that category, who it’s now primarily being aimed at!

        Is it normal or previously acceptable to test a vaccine only on healthy and primarily fit, young people, then administer it to those who are none of the above?

        .. and sorry, but “all UK GPs” DON’T have “resuscitation measures” to the level required “as a matter of course” – this is simply untrue and factually completely incorrect. Nothing “pretty wierd” about it – they’re GPs, not A&E.

        … and ‘yes’, lesson learnt, but it shouldn’t have happened and wouldn’t have if it had been tested in the normal way which is not ‘trials as we go along’.

        If the UK wants to be the guinea pigs for Phase Four of the trials, so be it, but that’s what it amounts to.

          Amazing how you’re an expert on absolutely everything, including the UK medical profession, here’s the facts:-

          “Regarding the temporary guidance on resuscitation facilities, BMA GP Committee chair Dr Richard Vautrey told Pulse: ‘Practices would have the necessary equipment and experience to deal with allergic reactions that can occur in their patients.”

          If we listened to you we’d have thousands more deaths, you make stuff up to feed your negativity, you actually want the vaccine to fail but it will succeed, cast iron certainty.

        London AI is exactly that, a bot.

        If you think you’re safe taking the worlds first mRNA vaccine, developed in world record time, then by all means take it. I don’t want you in the future with me, you serve no purpose other than consumption. Byeeee~

      2 out of 16,000 people got an allergic reaction from the vaccine.
      1 out of every 100 COVID patients die, 4 out of every 100 COVID patients get long COVID. Pick your battle.

    Its 2 people out of 40,000 vaccinated so far.. They are,or should be asked if they ever had any adverse reactions to medication or foods etc before being given the vaccine..but both being nurses it looks like that got overlooked.. I presume now if you suffer from adverse reactions then you would have to go to a clinic with resuscitation provisions

      Well that’s not what the MHRA are reported as saying, which is that the Pfizer vaccine can now only be administered “in facilities where resuscitation measures are available” and that the “MHRA (UK drug regulator) have advised on a precautionary basis that people with a significant history of allergic reactions do not receive this vaccination”.

      That doesn’t seem to leave too much room for anyone to “presume” anything, except to wonder if maybe it’s such a good idea to vaccinate the elderly and medically vulnerable first (those who were ‘shielding’), when they were excluded from the Phase 3 trials.

      The EU, at least, seem to be taking a different view – that the first mass vaccinations should be of younger, healthier care staff in what are essentially Phase 4 trials.

    More Brit bashing by a bitter expat pauper leaving in Isaan on a diet of barbaqued frogs and rats.
    You really are a first class tool John. The Oxford vaccine will be the route out of this mess for the developing world and that includes corrupt xnephobic banana republic’s like Thailand.
    Even you might be able to afford a couple of jabs in your arm it’s so cheap.

      The Oxford vaccine almost certainly will be – probably the only correct thing you’ve said in a long time.

      It will almost certainly be the eventual vaccine of choice in the UK as well, although whether that will still include you and Northern Ireland as it is effectively being absorbed by the remainder of Ireland, which the rest of the UK doesn’t seem to mind, is yet to be seen.

      The Pfizer vaccine looks increasingly like being little more than an expensive mistake, bought purely for political expediency – particularly after announcing that its vaccine production, which the UK has already bought and paid for this year although it will only get a small share, is being reduced from 100 million doses to only 50 million.

    Don’t listen to the idiot and don’t respond to him. He is a complete waste of your time and effort, he knows nothing about everything and everything about nothing.

    The best way to deal with a person like him is just let him waffle on without any response, which in reality is what he desperately seeks. Your response.

    All doctors surgeries have anaphylactic kits and a defibrillator. Part of what makes the vaccination program longer than people realised, is that it’s not a simple jab and go process. All patients are monitored for a minimum 15 minutes in case of any adverse reactions. This is common practice even with some meds, which is why all ambulances, OOH response vehicles and doctors surgeries must have anaphylactic kits.

    Don’t bother responding John as I will not waste my time reading it. Let alone respond to you.

      Unfortunately, Bobby m, the simple fact (and I do mean FACT) is that only just over 280 GP hubs are now in a position to administer the jabs, since an “anaphylactic kit” (ie an epi-pen) and “a defibrillator” are not the full resus measures now required, however much you may like them to be.

      In case you didn’t get it, that’s just over 280 GP hubs – that’s rather a long way off the 7,500 GP practices in the UK or the 1,500 ‘super hubs’ / access hubs.

      That may not suit your agenda or jingoism, but that’s simply how it is.

      Yep, I am totally in agreement with you, Bobby m. After a long period of giving him (Issan John) the benefit of the doubt, I will take everything he writes from now on with a pinch of salt. Not worth responding to him, as you say.

      So many twisted and selected “facts”, so many nonsense conclusions from illogical arguments – I’ve had more than enough of IJ.

      Thank you for putting it in a nutshell, Bobby m. He knows everything about nothing, and nothing about everything.

        Go figure, these guys best leave the Kingdom it’s far to dangerous for them every time they step out through their front door. It appears at present that this is 2 cases in 137000 vaccinations or a chance of 1 in 68500 against the chance of being killed ion the road in Thailand in a given year of about 1 in 285 in terms of population.

        The real problem is the poor souls that give them credence
