SARS-CoV-2, the beta coronavirus causing COVID-19, was isolated and categorizes as a novel one on January 7th, 2020 in China.[1] To date, official reports depict that SARS-CoV-2 has already infected 88.828.387 persons and caused 1.926.625 deaths worldwide.[2] On January 12th, 2020, China officials made public its genetic sequence, thus paving the way towards the research and development of diagnostic tests and vaccines. With regard to vaccination, e large number of clinical trials were designed and are currently undergoing, of which 189 are listed in ClinicalTrials.gov. [3] However, up to date, only three vaccines have published their respective phase III clinical trial results in peer-reviewed medical journals. [4-6] Vaccines are needed to reduce the morbidity and mortality associated with Covid-19, and multiple vaccine platforms as AZD1222 (AstraZeneca) [4], BNT162b2 (Pfizer/BioNTech) [5] and mRNA-1273 (Moderna) have been involved in the rapid development of vaccine candidates. Methodology: In this review, PubMed, Embase, Web of Science, Scopus, medRxiv, and bioRxiv were systematically scrutinized for peer-reviewed and preprint articles on phase III clinical trials of vaccines against SARS-CoV-2. In total, only three peer-reviewed papers fulfilling the search criteria were identified. Conclusions; All vaccine candidates should publish in peer-reviewed journals their efficacy and safety well before requesting approval to the national or international authorities…
