Recent studies confirm and detail some significant side effects. The focus has been on myocarditis, neurological conditions, and thrombotic events, primarily associated with the Moderna and Pfizer/BioNTech vaccines.
Myocarditis and pericarditis:
One of the most studied side effects is myocarditis, an inflammation of the heart muscle, and pericarditis, an inflammation of the heart lining. These conditions have been observed predominantly in young males, particularly following the second dose of the Moderna vaccine.
The incidence rate for myocarditis in this group is approximately 22 to 36 per 100,000, significantly higher than in the general vaccinated population.

A study by Yale researchers identified the immune response causing this inflammation, noting that it is not due to vaccine-created antibodies but rather an overactive generalized immune response.

Neurological conditions:
Newer studies have also detected neurological side effects. The largest vaccine safety study to date, involving 99 million vaccinated individuals, linked the first dose of Moderna and AstraZeneca vaccines to acute disseminated encephalomyelitis (ADEM), an inflammatory condition affecting the brain and spinal cord.

Blood clotting disorders:
Another concern has been thrombosis with thrombocytopenia syndrome (TTS), particularly following the Johnson & Johnson vaccine, which is no longer recommended in the U.S. due to these risks. The incidence of TTS is around 4 cases per million doses, highlighting the rarity but severity of this side effect

Potential long-term consequences of conditions associated with mRNA vaccines:
Myocarditis and pericarditis:
While myocarditis and pericarditis associated with mRNA vaccines are usually mild and resolve with treatment, they can lead to serious long-term health issues in some cases:
1. Heart failure: Severe inflammation can weaken the heart muscle, leading to chronic heart failure where the heart cannot pump blood efficiently.
2. Arrhythmias: These conditions can cause abnormal heart rhythms, which can be dangerous if not properly managed.
3. Cardiac scarring: Inflammation can leave scar tissue on the heart, impairing its ability to function normally

Neurological conditions:
The rare neurological side effects identified, such as acute disseminated encephalomyelitis (ADEM), also carry potential long-term consequences:
1. Permanent nerve damage: ADEM can result in long-lasting or permanent damage to the nervous system, potentially affecting motor and cognitive functions.
2. Chronic pain or neurological dysfunction: Some individuals might experience ongoing symptoms such as chronic pain, fatigue, or other neurological dysfunctions due to nerve damage

Thrombosis with thrombocytopenia dyndrome (TTS) can have significant long-term impacts:
1. Chronic blood clotting Issues: Survivors of TTS may face ongoing problems with blood clotting and might require long-term anticoagulation therapy.
2. Organ damage: Blood clots can cause damage to vital organs such as the brain (leading to strokes) or lungs (causing pulmonary embolism), which might result in permanent damage or functional impairment.
