Abstract

Introduction: The aim of this study was to examine the descriptive characteristics of randomized cont rolled trials published in PubMed on COVID-19 vaccines until May 30, 2021. Materials and Methods: Seventy three articles reached by scanning the keywords "vacci ne" and "COVID 19" in the PubMed database were reviewed by researchers, 33 randomized controlled trials (RCTs) related to COVID 19 vaccines were included in the study. According to the 17-item questionnaire created by the researchers, the descriptive features of included studies were examined. Results: The total number of investigative authors in 33 RCT articles published in approximat ely one and a half years from the outbreak of the pandemic was 946, and the average number of authors per article was 28.67±18.56. 39.3% of the articles were published in The Lancet and 27.2% in The New England Journal of Medicine. Of the vaccines used in the studies, 36.3% mRNA vaccine, 21.2% Inactivated vaccine, 18.1% Recombinant adenovirus vaccine, 12.1% Ch impanzee adenovirus-based vector vaccine, 6% BCG vaccine. 22.5% of vaccines are Phase 1, 12.9% Phase 2, 19.3% Phase 3, 3.2% Phase 4, 32.3% Phase 1- 2, 9% ,6 of them are Phase 2-3 studies. Conclusion: The majority of randomized controlled trials on COVID-19 vaccines are phase 1 and phase 2 trials for mRNA vaccines and inactivated vaccines. Studies are needed to evaluate the effect of vaccines on the pediatric age group. In studies, the safety of vaccines has been examined more, and there is limited information on efficacy and effectiveness of vaccines.

Özet

Amaç: Bu araştırmada 30 Mayıs 2021 tarihine kadar COVID-19 aşıları ile ilgili PubMed’de yayınlanmış randomize kontrollü çalışmaların tanımlayıcı özelliklerinin incelenmesi amaçlanmıştır. Gereç ve Yöntemler: PubMed veri taban ında “vaccine” ve “COVID 19” anahtar kelimeleri taranarak ulaşılan 73 makale araştırmacılar tarafından incelenmiş, COVID 19 a şıları ile ilgili olan 33 randomize kontrollü çalışma (RKÇ) ara ştırmaya dahil edilmiştir. Araştırmacılar tarafından olu şturulan 17 maddelik soru formuna göre dahil edilen araştırmaların tan ımlayıcı özellikleri incelenmiştir. Bulgular: Pandeminin ç ıktığı andan itibaren yaklaşık bir buçuk yıl içinde yayınlana 33 RKÇ makalesinde toplam ara ştırmacı yazar sayısı 946 olup makale ba şına ortalama yazar say ısı 28.67±18.56’dır. Makalelerin %39.3'ü The Lancet dergisinde, %27.2'si The New England Journal of Medicine'de yayınlanmıştır. Çalışmalarda kullanılan aşıların %36.3'ü mRNA aşısı, %21.2’si İnaktif aşı, %18.1'i Rekombinant adenovirus aşısı, %12.1'i Şempanze adenovirus tabanlı vektör aşısı, %6'sı BCG aşısıdır. Aşıların %22.5'i Faz 1, %12.9'u Faz 2, %19.3'ü Faz 3, %3.2'si Faz 4, %32.3'ü Faz 1-2, %9.6'sı Faz 2-3 çalışmasıdır. Sonuç: COVID-19 a şıları ile ilgili yapılan randomize kontrollü çalışmaların ço ğunluğu mRNA aşıları ve inaktif aşılar için yapılmış Faz 1 ve Faz 2 çalışmalarıdır. Çocuk yaş grubu üzerine aşıların etkisini değerlendirecek çalışmalara ihtiyaç vard ır. Çalışmalarda daha çok aşıların güvenliği incelenmiş olup aşıların etkinliği ve etkililiği üzerine daha kısıtlı bilgiler vardır.
