Is the flu jab not the same? Or tetanus booster (although isn’t that 10 years?)Has there ever been constant boosters used as a means of keeping society moving before ? we know over use of anti virals can lead to resistance just like antibiotics so I wouldn't be too confident in saying we don't need to worry about longterm damage just yet no matter how long the tech has been around , abuse something for long enough there's always repercussions imo.
