Oleh :

dr. Queen Sugih Ariyani

Herd immunity atau kekebalan komunitas menjadi isu yang marak dibahas di tengah pandemi COVID-19. Istilah ini sering digunakan saat membahas program vaksinasi dan upaya pemberantasan penyakit. Namun, apakah herd immunity benar dapat menjadi strategi untuk melawan COVID-19? Artikel ini akan mengulas pengertian herd immunity, langkah efektif untuk mencapainya, dan potensinya untuk mengendalikan COVID-19.

Definisi Herd Immunity

Herd immunity merupakan proteksi indirek (tidak langsung) yang bisa didapatkan oleh individu yang rentan terhadap suatu infeksi karena proporsi individu yang imun (kebal) terhadap infeksi tersebut sudah berjumlah besar dalam suatu populasi. Imunitas ini dapat diperoleh melalui infeksi alami ataupun vaksinasi.
