Moderna’s coronavirus vaccine has caused skin effects in patients after injecting the first dose of the product.
- Three skin side effects were observed by researchers after the injection of the first dose of the Moderna vaccine.
Sensitivity, erythema, induration… Here are the three skin side effects observed by researchers after the injection of the first dose of the Moderna vaccine. The doctor’s letterin which they develop their work, has just been published in the journal New England Journal of Medicine. The purpose of this study, explained in the letter, is to allay concerns about this Modera vaccine and to reassure patients who may have had skin reactions after the first dose: these only concern very few cases and do not are not systematic during the second injection.
To reach these conclusions, the researchers analyzed the post-vaccination reactions of 30,000 patients. According to scientists, these skin problems appeared “near the injection site after complete resolution of initial local and systemic symptoms associated with vaccination”, they explained in the letter.
Medicines to relieve skin reactions
Erythema is manifested by the red color of the skin. It is observed during infectious diseases – measles or scarlet fever – and certain skin diseases. The sudden appearance of erythema during the administration of a drug may be the first sign of an intolerance to it. Sometimes a more serious reaction of allergic origin follows. However, in the case of the Moderna vaccine, this does not appear to be the case.
Cutaneous induration is a hardening or thickening of the skin. This manifestation is generally localized and occurs in the epidermis. Along with these symptoms, the researchers also observed inflammation and rashes in some people, on average eight days after the injection. To relieve these side effects, patients took one of three medications: antihistamines, glucocorticoids, and antibiotic therapy. After an average of six days, all of their skin symptoms were gone.
Did these symptoms appear after the second dose?
All study patients received a second dose of the vaccine. After this, side effects were observed in only half of them: three had exactly the same symptoms as during the first injection, while three others had milder manifestations. The six other individuals who had presented skin reactions during the first injection did not have any this time.
The majority of patients who participated in the study were vaccinated at Massachusetts General Hospital, Boston, USA. According to The New York Times newspaper, this hospital uses both Moderna and Pfizer-BioNTech vaccines. People who were vaccinated with this second product had no post-vaccination skin side effects.
