Thrombocytopenia and splenic platelet directed immune responses after intravenous ChAdOx1 nCov-19 administration

Recently a rare and novel complication of SARS-CoV-2 targeted adenovirus vaccines has emerged:

thrombosis with thrombocytopenia syndrome (TTS)

Low platelets, clot formation at unusual sites and platelet-activating PF4-polyanion antibodies (reminiscent of heparin-induced thrombocytopenia).

In vitro and in vivo models

Platelet-targeted autoimmunity

We show that intravenous but not intramuscular injection of ChAdOx1 nCov-19 triggers platelet-adenovirus aggregate formation and platelet activation.

After intravenous injection, these aggregates are phagocytosed by macrophages in the spleen

This is followed by a pronounced B-cell response with the emergence of circulating antibodies binding to platelets.

Our work contributes to the understanding of TTS and highlights accidental intravenous injection as potential mechanism for post-vaccination TTS.

Hence, safe intramuscular injection, with aspiration prior to injection, could be a potential preventive measure when administering adenovirus-based vaccines.

Consistent results with mice and human platelets

Vaccines are routinely administered intramuscularly (i.m.) and trigger immune responses mainly in the draining lymph nodes

Based on our finding that adenoviral vaccine binds to blood platelets, we hypothesized that accidental intravenous injection of adenoviral vaccine might lead to platelet-adenovirus aggregate formation with platelet activation

The decline in platelet count was dose-dependent and correlated directly with adenovirus-positive platelets circulating in the blood one hour after i.v. injection

Intravenous but not i.m. injection of ChAdOx1 nCov-19 resulted in a strong increase in platelet-adenovirus aggregates

Intravenous administration of recombinant adenoviruses causes thrombocytopenia, anemia and erythroblastosis in rabbits, (Journal of Gene Medicine, 1999)

The systemic administration of a therapeutic dose of 5 x 10(11) infectious particles/kg (infusion time 20 min) led to an average reduction of 80-90% in the platelet count within 48 h.

Thrombocytopenia has been consistently reported following the administration of adenoviral gene transfer vectors.

The virus activates platelets and induces platelet-leukocyte aggregate formation.

Virus mediated gene therapy applications are still challenged by the resultant thrombocytopenia and the mechanism(s) of platelet-foreign particles interaction remains unclear.

Hello Everyone,My name is John Campbell and I am a retired Nurse Teacher and A and E nurse based in England. I also do some teaching in Asia and Africa when time permits. These videos are to help students to learn the background to all forms of health care. My PhD focused on the development of open learning resources for nurses nationally and internationally.


  1. Thank you for bringing this info to the public so that we can bring this to our medical providers and ask for aspiration before injection n tell government we don't want to wait years for them to mandate it. Your knowledge in this mater has open my mind to think deeper than just the problem but the results. May you continue spreading common sense of medicine that we all shood we know. May u be blessed to be a blessing. You are appreciated.

  2. Working for the government in the past. Well, they just change facts until it becomes history. Then everyone who is still alive are slim to none. Then the new crowd could careless. The government keeps doing their bullshit and so forth.

  3. So, in conclusion, if going for a vaccine just ask the injector to pull back and if they draw blood please stab again in a slightly different direction? I unfortunately read some of the comments and it's as conspiratorial as most comment sections. That's why I can't be bothered to watch most coronavirus related videos now. I've burnt out my ability to try to reason with antimaskers and antivaxxers. I've had my two shots. You're mask protected me, which you didn't give a fig about and now my vaccination protects me so I no longer care much about arguing. You want to get hospitalized with a virus you could have reasonably prevented contracting but didn't because you're too oppositional and defiant to follow community guidelines? Go for it. I no longer care. It's your choice now


  5. I got my vaccine in Jan 21. I asked if they "aspirated" and CVS said no they don't do that anymore " the needle is long enough… ???? I seen guys that use gear with a 1inch needle and still hit a vessel / nerve…

    Good video doc ?. They need to aspirate regardless covid or not

  6. So you could narrow this down to people who give the shots are not giving the shots the right way? They are doing them incorrectly! Correct?

  7. Apart from this specific mechanism, it should be obvious that the vaccine will have a different effect if injected into the blood circulation rather than into muscle tissue, so just from the point of view of consistency it would be surely be good to always inject into the muscle. Are they batting for Pfizer/Moderna perhaps?

  8. at the very least, as a patient, you can insist on aspiration. I refuse to get this poison, if I am put in a position where I am "forced", because I am a nurse, I will insist on aspiration and a Peds IM needle

  9. No it isn't rare, the vaccine is being shown to cause D dimer in many people, which is thousand of microscopic blood clots, especially in the lungs, and people who've been vaccinated are presenting with symptoms of breathlessness tiredness, and inability to exert themselves very much. This is concerning to say the least. Also Myocarditis a serious heart condition in younger males.

  10. can anyone tell me is it true that the UK country or any other europe country already achieved the herd imunity? did they really vaccinated 80% of the citizen?

  11. Hello Doc I have fibromyalgia I have rheumatoid arthritis in my hips spine knees wrists I have extremely high cholesterol,I'm on a few meds daily 5 I have first stage lung disease so I have serious concerns about even getting this vaccine . Can you help also I'm a Christian I'm afraid this can alter my DNA forever, my son died in 2020 I just want my soul to be the healthiest out of anything big concerns. ?

  12. Knowing what you do! I'm shocked that you even would agree with this nonsense of a vaccine to begin with! It's all a lie! And I know you know this! ???

  13. Knowing what you do! I'm shocked that you even would agree with this nonsense of a vaccine to begin with! It's all a lie! And I know you know this! ???

  14. Just got a warning from Facebook for putting a link to what I thought was a very well reasoned YouTube by Dr John Campbell. “Aspirate yo vacinate”
    FB Said I was offending community standards by quoting the YouTube screenshot of WHO statement on not requiring aspiration of covid AZ vaccine syringe. Waiting now to be banned from FB for 24 hrs but unsure what the sin is. Better go back to emailing friends!

  15. Can you explain to me regarding the adenovirus aggregate formation and platelet activation. My country are crazy to have vaccine without any research. It is a sin to force the population for injection.

  16. You make total sense an it could save lives, isn't that why we're getting vaccinated in the first place? They got their heads up their asses! Shacking my head. Thank you for taking the mystery out of the blood clot situation.
