The COVID-19 pandemic is testing the resilience of robust health systems around the world. This may be impacting you in many different ways, such as creating additional anxiety or exacerbating other medical or therapy issues related to your Inherited Metabolic Disease (IMD). In this difficult period, MetabERN underlines the critical importance of sustaining efforts to prevent, diagnose and treat Inherited Metabolic Diseases (IMDs) assuring the continuation of the quality of care provided to you. To help the entire metabolic community, we have developed some recommendations that aim to support all rare IMD patients and caregivers during the COVID-19 emergency.

COVID-19 Vaccine Recommendations

The experts of MetabERN recommend that IMD patients get vaccinated against COVID-19 when they are offered this opportunity.

All IMDs should be considered as a high priority for COVID-19 vaccination. Patients who present a high risk of acute metabolic decompensation, respiratory or cardiac complications, and frequent exacerbation induced by infection, such as those with AOA, PM-MD, C-FAO and LSD, should be vaccinated with the highest priority.

Based on the current evidence, our experts’ advice is to use any vaccine available in the country, with no particular contraindications for any metabolic disease.
