I keep hearing vaccination being promoted, but the last major study I saw showed no statistically significant difference in natural immunity + vaccination versus simple natural immunity. This also seems to be a topic treated as a fringe conspiracy theory instead of an extremely serious health issue worthy of a large amount of resources dedicated to giving us an answer. One certainly could be forgiven for thinking the vaccine has become a larger political issue than health issue for both sides.
