  #MyBodyMyChoice is a well-known hashtag originally created to advocate for
women's rights, often used in discourse about abortion and bodily autonomy. The
Covid-19 outbreak prompted governments to take containment measures such as
vaccination campaigns and mask mandates. Population groups opposed to such
measures started to use the slogan "My Body My Choice" to claim their bodily
autonomy. In this paper, we investigate whether the discourse around the
hashtag #MyBodyMyChoice on Twitter changed its usage after the Covid-19
outbreak. We observe that the conversation around the hashtag changed in two
ways. First, semantically, the hashtag #MyBodyMyChoice drifted towards
conversations around Covid-19, especially in messages opposed to containment
measures. Second, while before the pandemic users used to share content
produced by experts and authorities, after Covid-19 the users' attention has
shifted towards individuals.
