This is an example of cross reactivity, like if you're allergic to cashews you might also be allergic to pistachios or mangos since they're all in the same plant family.

这是一个交叉反应的例子，就像如果你对腰果过敏，你可能也对开心果或者芒果过敏，因为它们属于同一个植物系。

And it takes about two weeks after the second dose for you to have maximal immune response there will be quite a bit of cross reactivity for smallpox and monkeypox because the viruses are relatively similar.

第二次注射后大约需要两周时间才能产生最大的免疫反应，天花和猴痘会有相当多的交叉反应，因为这两种病毒相对相似。
