Well, minor effect in most cases. Adverse effects are usually mild. A recent US study also showed that in 92% of cases, the side effects seen after injection of RNA vaccines are mild. This is confirmed in the field by the Medicines Safety Agency (ANSM), which updates its data every month.
Injection site pain, fatigue, headache, joint pain, chills, fever, diarrhea are the main effects with RNA vaccines. Note that comirnaty may be accompanied by insomnia, excessive sweating (day or night), loss of appetite or even a feeling of weakness or lack of energy. For the ANSM, “these effects are known and, for some, common to any vaccination. Unpleasant, they are not serious and disappear spontaneously within a few days.”
Others, which are also known, may appear, but less frequently. They actually occur from 1 in 100 to 1 in 1,000. We are talking about pain in the extremities (arms, legs), itching at the injection site, swelling of the lymph nodes or even dizziness (for Moderna Vaccine) here. ,
Fortunately, “serious” effects are rare.
The ANSM also notes more serious events, but much less frequent. These include facial paralysis (which usually resolves within a few weeks) or facial swelling, “which occurs in patients who have had cosmetic facial injections”.
Very rarely (less than 1 in 10,000 cases) there may be inflammation of the heart muscle (myocarditis) or inflammation of the lining outside the heart (pericarditis), sometimes causing shortness of breath, palpitations, or chest pain. In this case, contact a healthcare professional (doctor or 15) immediately for treatment.
Same thing if you have a skin reaction causing red spots or spots on the skin that look like a target. Even though the number of these cases is uncertain, it should not be taken lightly.
