"輪狀病毒（Rotavirus，簡稱RV）是一種雙鏈核糖核酸病毒，屬于呼腸孤病毒科。它是嬰兒與幼兒腹瀉的單一主因[1]，幾乎世界上每個大約五歲的小孩都曾感染過輪狀病毒至少一次[2]。然而，每一次感染后人体免疫力會逐漸增強，後續感染的影响就会减轻[3]，因而成人就很少受到其影響[4]。"

the rotavirus vaccine is an attenuated vaccine...meaning that the vaccine basically contains weakened rotavirus molecules...

when the vaccine is injected to the body....the vaccine activates the immune response to produce immunity....meaning that you are basically "forcing" the immune system to develop immunity against the virus
