  1. 1 = A search was conducted in the GISAID database for all sequences containing the corresponding substitution (https://www.epicov.org/, accessed on the 7th of April 2022). 2 = A search was conducted in the PubMed Central database for articles from 2019 until today, containing the keywords “SARS-CoV-2” and the corresponding mutation. Next, the search was repeated but the keywords had to be present in the abstract to yield a result (https://www.ncbi.nlm.nih.gov/pmc/, accessed on the 7th of April 2022)
