Were masks effective in stopping the spread of Covid 19?
The data suggests it's inconclusive whether or not masks were effective in stopping the spread of Covid-19.  There's evidence to support that they may have caused more harm than good with certain demographics, however Covid-19 was weaponized by political agendas. There are studies to support whichever side of the aisle you want to align with. It is widely accepted by both ends of the political spectrum that natural immunity is effective in stopping the spread of viruses.
