How does the mRNA vaccine work and are there any side effects?

This article goes through the things you need to know before you make the decision to take a COVID vaccine.

Global vaccination coverage

Let’s get started. So the goal is global vaccine coverage, i.e. to give everyone in the world the coronavirus vaccine, as soon as possible. Never before has a vaccination campaign been carried out at such a pace and volume, especially with a vaccine that was developed in record time and whose principle of action is completely new. Never before in the history of the world has a vaccine based on mRNA technology been injected into humans.

We first need to understand the main features of the SARS-CoV-2 virus and the COVID-19 disease it causes in order to understand how the vaccine works and affects the body. Then we can ask, is the vaccine effective and safe?


Coronaviruses are a tribe of RNA viruses that cause disease in humans and animals. Coronaviruses were discovered in the 1960s and found to be common causes of human rhinitis. Four of the seven coronaviruses that infect humans cause mild flu symptoms: OC43, HKU1, 229E, and NL63. 

According to Karma’s rule, ”everyone reaps what he sows” and everyone will eventually have to face the consequences of his actions and either suffer them or atone for them.

COVID-19 disease

The SARS-CoV-2 virus causes respiratory infections. A small proportion of those infected has an infection that leads to hospitalization. Fatal COVID-19 is associated with advanced age and underlying diseases. Below is a table of deaths in Finland

Surce: THL koronakartta updated 11.1.2022

In Finland, the median life expectancy is 85 years for women and 77 years for men. The graph shows that coronary deaths occur in old or very old age groups. In these age groups, death is a natural event even without a corona. In Finland, 150 people die every day and on average there are two corona-related deaths per day during an epidemic. By way of comparison, the normal number of deaths in nursing homes in Finland is around 1600 per month. The total number of corona-related deaths is 1666 over a period of over 2 years.

For a person under 60 in basic health, the corona is not as dangerous a disease as has been suggested. Only 123 people under the age of 60 have died during the whole epidemic. The deaths of those under 60 are linked to a serious underlying disease. However, age over 70 rapidly increases the risk. No one under the age of 30 has died from covid-19 in Finland!

Patients in intensive care usually suffer from respiratory symptoms (pneumonia). If necessary, oxygenation is supported by respiratory therapy. There is no actual cure for the disease. Treatment is therefore symptomatic. Intravenous cortisone suppresses cytokine storm, which is suspected to be one of the factors contributing to the onset of severe COVID-19.

Spike protein

The SARS-CoV-2 virus binds to ACE2 receptors in the body using a spike protein and transfers its RNA code into the cell. The cell begins to replicate the virus and when there is a sufficient amount of virus in the body, the symptoms of the disease appear.

The amount of spike protein in the body increases as the virus multiplies in the body and around a week after infection any bleeding and/or clotting problems begin.

Only now are we beginning to understand what causes severe COVID-19 disease and long-term multiple (Long COVID) problems. One part of the virus is emerging as the cause of the problems. It is a spike protein.

Problems caused by spike protein

Blood clots and haemorrhages

The risk of blood clots in coronary heart disease has long been known and researchers have come to the conclusion that coronary heart disease is primarily a cardiovascular disease rather than a respiratory infection.

Spike protein can cause excessive blood clotting, but it can also cause hemorrhaging. The effects on blood are manifold and you can read more about them in this study.

Neurological problems

The spike protein passes through the blood-brain barrier and when the spike protein enters the brain, it can cause brain fog, relentless fatigue, buzzing around the body, dizziness, hearing or vision problems, changes in taste or smell, and other neurological symptoms. In the worst cases, it can cause a cerebral infarction or a cerebral hemorrhage.

Cardiovascular symptoms

The spike protein binds to the ACE2 receptor in the cell. ACE2 receptors affect blood pressure and heart rate. One major class of hypertension drugs is ACE inhibitors, whose efficacy is based precisely on the effects of ACE receptors.

When the amount of spike protein in the body increases and sticks to the ACE receptors, it can cause slow heart rate, fast heart rate, arrhythmias, or a wide variety of heart rate-related symptoms or blood pressure problems.

Blood pressure can suddenly rise to a very high level or fall too low.

Spike protein is not part of the human body

Spike protein does not belong in the human body and the body tries to destroy it as efficiently as possible. Once a cell is infected and replicates the virus, the organs will destroy the cell if they can. An organ with a large number of cells that produce spike protein is damaged because the contaminated spike protein-producing cells are destroyed.

Development of vaccines

The first SARS-CoV-2 virus infections were reported on 7 January 2020 in Wuhan, China. In December 2020 of the same year, the first Comirnaty injections were given. The evolution, therefore, took less than a year. Normally, it takes 8-10 years for a safe vaccine to reach clinical trials. This time was reduced to 8-10 months and, for example, Pfizer’s actual trial of the vaccine in volunteers took two months before the vaccine was granted an emergency exemption. The first vaccines were tested in humans as early as March 2020, just over two months after the first coronavirus infection, despite the near-unanimous consensus among experts that it is extremely challenging to develop a working vaccine for coronavirus, as for other respiratory viruses. A good example of this is the influenza vaccine, which over the decades has failed to eradicate or even reduce the incidence of influenza worldwide.

Earlier developments

Koronavirusrokotteita kehitettiin eläinkokeilla SARS-epidemian jälkeen 2002. Epidemia Coronavirus vaccines were developed in animal studies after the SARS epidemic in 2002. However, the epidemic ended on its own, and animal trials did not warrant further development.

Animals that had received the mRNA vaccine subsequently developed a hypersensitive reaction if they encountered wild-type viruses after vaccination.

TThe study highlighted the need for caution if a similar mRNA injection is given to humans. It was previously found that cytokine storm in humans is a putative factor in severe disease. A cytokine storm is a hypersensitive reaction.

“These SARS-CoV vaccines all induced antibody and protection against infection with SARS-CoV. However, the challenge of mice given any of the vaccines led to the occurrence of Th2-type immunopathology suggesting hypersensitivity to SARS-CoV components was induced. Caution in proceeding to application of a SARS-CoV vaccine in humans is indicated.” link to research

How does the vaccine work?

The new types of mRNA vaccines are not vaccines in the strict sense of the word. The vaccine provides protection against the pathogen and prevents the spread of the pathogen in vaccinated individuals. A conventional vaccine contains an attenuated pathogen (virus) or parts of it. These conditions are not met for mRNA spikes. The expression ”injection” will be used and, as already stated. This technology has never before been used in vaccines or injected into humans at such a rate and volume.

Turn your body into an efficient spike protein factory

The mechanism is the same for all mRNA injections. Their purpose is to get the human cells to produce a spike protein, and it is the spike protein that causes the problems.

Three vaccines, same effect

In Finland, three different manufacturers of mRNA injections are in use. mRNA injections are called Comirnaty (Pfizer/BioNTech) and Covid- 19 vaccine Moderna (Moderna). In these, the mRNA code is introduced into the cell in a nanocapsule.

In Vaxzevria (AstraZeneca) adenovirus injection, the code is embedded inside the chimpanzee adenovirus. In it, the body also gets an immune response to the adenovirus. AstraZeneca is only injected into people over 65 because younger people have deep vein thrombosis, such as sinus thrombosis of the brain.

The picture downloaded from Finnish Institute for Health and Welfare shows how the vaccine works. A person’s own cells are programmed to produce a spike protein, which the body recognizes as a foreign substance and makes antibodies to it, while trying to destroy the contaminated cell.

In practice, an autoimmune reaction occurs in the body, especially with boosters, because the body attacks its own cells. This happens because the cells have a modified genome, the viral mRNA code. The body does everything it can to protect the genome and destroy the infected cells. It has been very difficult to introduce the mRNA into the cell because the body has destroyed the foreign mRNA particles in minutes.

Below is a video of Moderna’s salesman talking about how the problem was solved seven years ago. Cells can be made to produce the desired substance at any time!

According to a study by Pfizer that was leaked on the web, mRNA is transferred (accumulated) in the liver, spleen, bone marrow, adrenal gland, and ovaries in the highest concentrations after injection. nRNA is therefore not immediately destroyed, as is implied or assumed, and its effects (i.e. the formation of cellular spike protein) are not confined to the local shoulder area where the injection is administered but are intensified in the above-mentioned organs.

Are there any side effects of the injection?


Adverse reactions to vaccines in Finland are collected by Fimea. The data are updated monthly. Click here to see latest situation. Nearly 68% of adverse reactions are serious. There were about 15 400 (11.1.2022) reports still to be processed, which are not yet reflected in the statistics. So there is a lot of vaccine adverse reactions reported. However, it should be remembered that a study in the USA shows that only 1% (max. 10%) of vaccine adverse reactions are recorded in the registers. There is a huge number of adverse reactions that are not reported, whether by doctors, medical staff, the persons concerned or their relatives.

Are the side effects dangerous?

After the injection, you should listen to how you feel. The side effects immediately after the injection are already relatively well-reported and you can see them here.

Long-term effects are not yet known. However, the injection starts the production of spike protein in the body immediately, but it may take weeks before unexplained bleeding or blood clots, neurological symptoms, muscle twitching, arrhythmias, blood pressure problems, etc. occur.

Severe abdominal pain after eating, which gets worse over the days, may indicate a lack of oxygen in the intestines. Mesenteric ischemia in the abdomen can develop slowly but are very dangerous if treatment is not received in time.

If your relative or friend has a serious seizure immediately or after weeks of the injections and there is no reasonable explanation, it is worth remembering the covid injection taken earlier. A bleed or blood clot can form in a vital organ without warning.

The injection does not protect against infection and does not prevent further transmission of the disease. What are its benefits?

SIt is a very profound question. The injection has an emergency authorization and we know absolutely nothing about its long-term effects. Yet its use is being extended to younger age groups all the time. The risk-benefit ratio in this situation is questionable.


Omicron evaded vaccines. Omicron is also more transmissible to vaccinated people. At the moment it seems that the world’s biggest vaccination campaign has failed completely.
