Response to: myositis after SARS-CoV-2 vaccination occurs more frequently than assumed and is probably causally related.

We thank Finsterer et al. for the attention paid to our publication; we recognize the validity of the points mentioned in their letter to the editor and will try to answer the observations made.

Idiopathic inflammatory myopathies linked to vaccination against SARS-CoV-2: a systematic review.

The COVID-19 pandemic represents a global health problem, which has been mitigated by the opportune introduction of vaccination programs. Although we already know the benefit that vaccines provide, these are not exempt from adverse events which can be mild to deadly, such as idiopathic inflammatory myopathies, in which a temporal association has not been defined. It is for this reason that we carried out a systematic review of all reported cases of vaccination against COVID-19 and myositis.

Dermatomyositis post vaccine against SARS-COV2.

Background: Dermatomyositis belongs to an infrequent group of diseases predominantly found in patients older than 40 years old and is characterized by dermal and muscular findings. This disease presents itself as proximal, ascending and symmetric weakness and typical dermatosis with findings such as elevated muscle enzymes, altered electromyography and typical changes in muscle biopsy; as of today, the etiology of the disease in unknown. The COVID-19 vaccine has been a fundamental tactic to achieve control of the coronavirus (SARS CoV2), and it's clear that the benefits of getting the vaccine overweight the risks that might come along with it.
