Another nail for those who endorse lockdowns. Seems for you to maintain your natural protection i.e antibodies, you need a degree of exposure to the virus or your body will just forget it was a problem to begin with. It reminds me of the old wives tale to not over clean your kItchen to protect yourself from allergies.
The point here is even if we vaccinate, without irradicating the virus completely, we will also need to keep it within society for it to be effective. Meaning all the hard work of protective the vulnerable has been delaying the inevitable because at some point they will have to take responsibility for their own safety anyway. Something many on here said should have been the strategy to begin with.
