Abstract

Amaç: COVID-19 salgını tüm dünyayı etkilemiştir. Bu makale, Türkiye'de günlük Kovid-19 vakaları, ölüm ve iyileşmeler ile günlük COVID-19 aşıları arasındaki ilişkiyi ve aşı çalışmalarının etkinliğini araştırmayı amaçlamaktadır.

Araçlar ve Yöntem: Türkiye Cumhuriyeti Sağlık Bakanlığı verilerine dayanarak aşı dozları ile COVID-19 vakaları, ölüm sayısı ve iyileşen sayısı arasındaki ilişkinin araştırılması amaçlandı. Çalışmada, aşının ilk dozunun uygulandığı 13 Ocak 2021 ile günlük verilerin mevcut olduğu son tarih olan 31 Mayıs 2022 arasındaki dönem incelendi. Veriler Türkiye COVID-19 Pandemi İzleme Ekranı (TURCOVID19) platformundan elde edilmiştir. Toplam 504 günlük veriler analiz edildi.

Bulgular: Günlük ilk doz aşı sayısı 1.458.245, 2. doz aşı sayısı ise 912.226 olup, 1. ve 2. doz aşı sayısında yüksek değerler ortaya çıkmaktadır. Aşılama oranlarının yüksek olduğu dönemlerde günlük ölüm sayılarında azalma ve günlük iyileşme oranında artma görülmüştür. İyileşen vaka sayısı aşının 3. ve 4. dozlarının uygulanmasından sonra en yüksek seviyeye çıkmıştır.İki doz aşı aldıktan sonra enfekte olan kişi sayısının aşılanmayan enfekte kişi sayısına kıyasla önemli ölçüde azaldığı görülmüştür.

Sonuç: Dünya çapında ve Türkiye'de yapılan çeşitli çalışmalardan elde edilen sonuçlar, COVID-19 aşılarının hastalık yükünü azaltmadaki etkinliğini tutarlı bir şekilde ortaya koymaktadır.

Analysis the Impact of COVID-19 Vaccine Doses on Daily Cases, Deaths, and Recoveries: A Statistical Analysis of Turkish Public Data

Abstract

Purpose: The COVID-19 epidemic has affected the entire world. This article aims to investigate the relationship between daily COVID-19 cases, deaths and recoveries, and daily COVID-19 vaccines in Turkey, and the effectiveness of vaccine studies.

Materials and Methods: Based on the data from the Ministry of Health of the Republic of Turkey, this study aims to investigate the relationship between vaccine doses and COVID-19 cases, deaths, and recoveries. The analysis covers the period from January 13, 2021, when the first dose of the vaccine was administered, to May 31, 2022, the most recent date for which daily data is available. The data were obtained from the Turkey COVID-19 Pandemic Monitoring Screen (TURCOVID19) platform, with a total of 504 days of data being analyzed.

Results: The daily number of first-dose vaccinations was 1,458,245, and the daily number of second-dose vaccinations was 912,226, with high values observed for both the first and second doses. During periods of high vaccination rates, a decrease in daily death counts and an increase in daily recovery rates were observed. The number of recovered cases reached its peak after the administration of the third and fourth doses of the vaccine. It was also observed that the number of individuals infected after receiving two doses of the vaccine was significantly lower compared to the number of infected individuals who were unvaccinated.

Conclusion: The results obtained from various studies conducted worldwide and in Turkey consistently demonstrate the effectiveness of COVID-19 vaccines in reducing the disease burden.
