Are Catholics obliged to follow scientific evidence that they find disreputable with respect to the Covid-19 pandemic?

Like most of the planet, I've been taking in gobs of information about Covid-19 and vaccinations. The latest news I read was that even the horribly [abortion tainted](https://lozierinstitute.org/update-covid-19-vaccine-candidates-and-abortion-derived-cell-lines/) Johnson and Johnson vaccine is permissible to take as long as there are no alternatives and that the Pfizer and Moderna vaccines are somehow examples of the means justifying the ends because of their remoteness. So that first paragraph notwithstanding (I mean completely discounting abortion from this answer which has short circuited what I think is a more important and more imperative thing for the average Catholic to deal with), do we as Catholics need to "Trust Dr. Fauci"? Like the President implores us to? Or should we trust our consciences. Our parish priest said that if we choose to not get the vaccine we should protect society in other ways, but can that mean telling our neighbors to chill out, take off their masks and stop worrying so much about Covid-19; trusting God, if not the odds over the science? Or does it mean that we still need to believe everything else that the authorities tell us about Covid-19 and more-or-less become hermits just so we can avoid taking a vaccine?
