In contrast with adults, children infected by severe acute respiratory syndrome-corona virus (SARS-CoV) develop milder clinical symptoms. Because of this, it is speculated that children vaccinated with various childhood vaccines might develop cross immunity against SARS-CoV. Antisera and T cells from mice immunised with various vaccines were used to determine whether they developed cross reactivity against SARS-CoV. The results showed no marked cross reactivity against SARS-CoV, which implies that the reduced symptoms among children infected by SARS-CoV may be caused by other factors.
与成人相比,感染严重急性呼吸综合征冠状病毒(SARS-CoV)的儿童临床症状较轻。因此,据推测接种多种儿童疫苗的儿童可能会产生针对SARS-CoV的交叉免疫。使用来自用各种疫苗免疫的小鼠的抗血清和T细胞来确定它们是否产生针对SARS-CoV的交叉反应性。结果显示对SARS-CoV没有明显的交叉反应性,这意味着感染SARS-CoV的儿童症状减轻可能是由其他因素引起的。
