One of the sides? Like Biden and Kamala saying they wouldn't trust the Trump vaccine?
The reality is that the mRNA vaccines were basically ready to go within a few weeks, and political dregs kept it from being approved even faster. But its inadvisable to change the bureaucratic infrastructure for disasters during disasters, and so here we are.
But yes, the crowd that Trump tends to seek support from is anti-science.
Every partisan is perfectly happy to claim that they are following science and usually fail to modify their behavior when confronted with actual science. That holds across the political spectrum. The Trump crowd aren't anti-science, they simply tend to anti-authority. I guarantee you that they're highly pro-science on the issues where the science agrees with them.
