Reminds me that yesterday I tried googling around the topic of how covid affects fertility (eg. "covid fertility") and nearly every result that comes back is about vaccines not affecting fertility. Okay, thanks Google, but how about the actual disease? Results were a fair bit more relevant by adding "disease" to the query, but still got one or two about vaccines.
I don't think you can call that behaviour favouring left. It feels as though they're creating vaccine hesitancy.
