<![CDATA[Pendahuluan: SARS-CoV-2 merupakan agen virus penyebab COVID-19, penyakit yang menjadi wabah secara global. Gejala infeksi COVID-19 beragam, sebagian besar dengan derajat ringan, namun sekitar 14% mengalami perburukan.. Vaksinasi influenza diperkirakan dapat berperan sebagai faktor protektif terhadap COVID-19. Metode: Tinjauan literatur mengenai vaksin influenza dan COVID-19 menggunakan beberapa sumber seperti Google Cendekia, PubMed, dan WHO. Hasil: Influenza dan COVID-19 menunjukkan gejala serta karakteristik kelompok risiko tinggi yang serupa. Koinfeksi virus influenza dapat meningkatkan keparahan gejala COVID-19. Beberapa penelitian menunjukkan bahwa vaksinasi influenza berasosiasi negatif dengan kematian akibat COVID-19, dan dapat mengurangi keparahan klinis. Mekanisme imunitas bawaan yang dipicu oleh vaksinasi dapat menghasilkan efek protektif, hal ini dapat memberikan peluang yang lebih baik dalam melawan virus. Simpulan: Selain mengurangi risiko koinfeksi influenza dengan COVID-19, vaksin influenza juga dapat berperan sebagai agen protektif terhadap COVID-19.Introduction: SARS-CoV-2 is the viral agent that causes COVID-19, a disease that is becoming a pandemic. The symptoms of COVID-19 are diverse, about 14% of individuals experience deterioration. Influenza vaccination may have a role as a protective factor in COVID-19. Methods: A literature review on influenza vaccine and COVID-19 is conducted using several sources such as Google Scholar, PubMed, and WHO. Results: Influenza and COVID-19 show similar symptoms as well as same characteristics of high-risk groups. Influenza virus co-infection can increase the severity of COVID-19. Previous studies have shown that influenza vaccination was negatively associated with mortality from COVID-19, and could reduce the severity of clinical symptoms. The innate immune mechanism triggered by vaccination could produce a protective effect. Conclusions: Apart from reducing the likelihood of influenza coinfection with COVID-19, influenza vaccine can also act as a protective agent against COVID-19,]]>
