Intravenous injection of mRNA Covid vaccine can induce acute myopericarditis in mice

This study provided in vivo evidence that inadvertent intravenous injection of COVID-19 mRNA vaccines may induce myopericarditis. Brief withdrawal of syringe plunger to exclude blood aspiration may be one possible way to reduce such risk.

Adenovirus-induced thrombocytopenia – aspiration before vaccination with #coronavirus vaccines!

Dr John Campbell discusses the need for aspiration before coronavirus vaccination, and the technique for doing so.

Thus, one of the hypotheses linking the vaccine to the occurrence of severe thrombosis could be an accidental intravenous injection which, in the presence of factors not fully identified, would generate a discordant immune reaction with activation of the platelets, potentially associated with a NET effect or with a decrease in the level of ACE2 on the surface of endothelial cells, leading to an increased risk of thrombosis. A simple way to overcome this hypothetical accidental intravascular injection could be to verify the absence of blood return during vaccination [aspiration], which is not currently recommended by the [French] Ministry of Health

 

Original excerpt In French:

Ainsi, l’une des hypothèses liant le vaccin à la survenue de thrombose grave pourrait être une injection intraveineuse accidentelle qui, en présence de facteurs non intégralement identifiés, engendrerait une réaction immunitaire discordante avec activation des plaquettes, potentiellement associé à un effet NET ou à une diminution du taux d’ACE2 à la surface des cellules endothéliales, conduisant à un sur-risque thrombotique.

Un moyen simple de pallier cette hypothétique injection intravasculaire accidentelle pourrait être de vérifier l’absence de retour sanguin lors de la vaccination, ce que ne recommande actuellement pas le ministère de la santé
