On February 17, the Permanent Vaccination Commission (STIKO) published its latest Epidemiological bulletin. In the specialist weekly, the Robert Koch Institute publishes official communications and scientific work on notifiable diseases. The STIKO is a group of voluntary experts, currently composed of 18 people, based at the Robert Koch Institute in Berlin.

In this issue, experts now recommend aspiration for intramuscular administration of COVID-19 vaccines – contrary to general recommendations for vaccinations and World Health Organization WHO specifications – when application of a COVID-19 vaccine intramuscularly.

When injecting, i.e. administering medication using a syringe, aspiration occurs when the plunger of the syringe is briefly withdrawn. When injecting into tissue, in the case of COVID vaccinations in the arm muscle, it is possible to determine whether a vessel has been accidentally hit.

The STIKO explains this recommendation on the grounds that it “should further increase vaccine safety”, according to the presentation of the medical journal. On page 14 of the current Newsletter 7/22 He says: “Vaccination is strictly intramuscular (im) and not intradermal [in die Haut]subcutaneous [unter die Haut] or intravascular (iv) [in ein Gefäß hinein] administer.”

Strong Epidemiological bulletin in an animal model “after direct intravenous injection of an mRNA vaccine, perimyocarditis” occurred, that is, inflammation of the pericardium. This event has been documented clinically and histopathologically (microscopic diagnosis of the disease on tissue samples). The original text of the most recent recommendation (means accidental: occurred by chance; not necessarily part of the clinical picture) reads as follows:

“Although accidental intravascular (located in blood vessels) Injections with an im vaccine application occur only rarely, with COVID-19 vaccinations, aspiration with im application makes sense to further increase vaccine safety.”

as a quote, the result of a series of studies from November 2021 is given. The title of the publication is “Myocarditis after COVID-19 mRNA vaccine: A case series and determination of the incidence rate”. It says about the examinations on 21 patients in the conclusion:

“Myocarditis is a rare adverse reaction associated with COVID-19 mRNA vaccines and occurs at a significantly higher incidence in adult males than in the general population. Recurrence of myocarditis after a subsequent dose of mRNA vaccine is currently unknown.

A study of “BALB/c mice” (an immunodeficient albino strain of the lab-bred house mouse) from August 2021 concluded:

“Intravenous injection of the COVID-19 mRNA vaccine can induce acute myopericarditis in a mouse model.”

The aspiration recommendation was discussed and demanded by critical physicians and scientists, such as Sucharit Bhakdi and Wolfgang Wodarg, early on in the possibility of COVID vaccinations. However, most mainstream media immediately categorized this as “conspiracy myths.” Wodarg wrote about this on his October 29, 2021 page:

“A particularly high risk arises from an accidental intravenous injection of the” vaccines “. The formation of spikes can then cause great damage in the endothelium of the depressional system (right atrium – myocardium-pulmonary vascular tree) (…) conclusion: Contrary to STIKO recommendations, the risk of venous administration by aspiration must be minimized before each im injection.

At Pathology Conference II, it says to treat IM injections for COVID vaccinations:

“Pathologist Prof. Burkhardt explains that the information from the WHO that “aspiration” is not necessary for vaccination is incorrect. Before administering the vaccine, it must be ensured that no blood vessels have been affected, otherwise the blood vessels will be damaged and substances may enter the blood.

The medical journal recalls that for all other vaccinations except the COVID-19 vaccination, STIKO generally does not recommend aspiration when administering the vaccine. The previous definition and STIKO recommendation for intramuscular injections for vaccinations are:

“The STIKO advises that aspiration prior to injection is not necessary and should be avoided with intramuscular injections to reduce pain. Blood vessels in body sites recommended for vaccine injection (M. vastus lateralis or M. deltoideus) and within reach of the needle are too small to permit inadvertent intravenous administration.

The latest STIKO recommendation was immediately embraced by medical associations. This is what is indicated on February 18 on the website of the Association of Compulsory Health Insurance Doctors of Westphalia-Lippe practical info:

“Aspiration makes sense for intramuscular application to further increase vaccine safety.”

The safety and effectiveness of corona vaccines are controversial issues. Many scientific, political and media experts consider them safe and effective because they largely prevent the risk of serious COVID-19 disease and the benefits of a corona vaccination outweigh the risks and side effects. The long-term side effects of vaccinations are generally not known. Side effects such as the ADE (antibody-dependent enhancement) effect have not been reported with doses of vaccine administered in the billions worldwide. Many experts also rule out the possibility that gene sequences from mRNA vaccines, for example, are incorporated into human DNA.
