adjl 05/21/21 10:32:58 PM #12:	SunWuKung420 posted... Many people were exposed to covid, never exhibited symptoms of covid, and test positive for covid antibodies. Do they need a vaccine that isn't has good as their own immune system? Are they not a part of herd immunity? Most observations are finding that natural immunity to Covid is only lasting about 3 months. Even if somebody's already immune due to having been infected, a vaccine will enhance that immunity to make it more effective and last longer. Natural infections can provide herd immunity, but it's much more reliable and measurable to establish it through vaccines than to rely on that. Perhaps more saliently, though, it's significantly easier to just vaccinate everyone that can be vaccinated than to test everyone for Covid antibodies and vaccinate the ones that turn up negative, especially considering that those antibodies will fade and people that test positive for them would need to be retested regularly to ensure they still have immunity. The worst that redundantly vaccinating people will do is make them feel like they have a bad cold twice instead of once, which is really a pretty trivial cost. --- This is my signature.
