Interesting thoughts as always Chris. The bold is in question though isn't it? Saw a 20 something interviewed on Today this morning that caught it a 2nd time so antibodies don't have a lengthy protection as hoped I think.
I didn't see this, but I know the length antibodies are in the system also seem dependent on how severe the illness was. Without getting too technical, if the infection is only in the upper airway the immunity doesn't seem to last as long as if it's in the lower airways. Of course, like Chad's facial hair, things keep changing.
It depends on who you want to listen to and/or whether you look at the glass as half full or half empty. We never achieve full immunity or full coverage or full this or that but in the overwhelming number of cases, the typical outcome is that someone who clears a virus maintains an immunity to that virus for a meaningful amount of time (define as you will). THEN add to the conversation/science pot whatever things like your ability to fight off a future infection "better" because it has seen that protein before, even if your antibody load isn't technically enough to outright prevent an infection. So, while there is technically a potential that immunity isn't strong or long lasting...it is also possible I will win the lottery, a third party candidate will win the election and my dad will live to 100. The odds and evidence are not particularly leaning in that direction.
There have been a few stories of someone "getting it twice". Some theories have been that they never actually cleared the virus the first time. With improved and additional testing I don't know if this is still a theory or what.
I saw a story last night where a "doctor" (I don't know what kind of doctor) was excited to share how basic fabric masks can actually protect the wearer AND help build herd immunity. WHAAAT? What she was saying was that the fabric masks provide a basic barrier that slows the virus down even if it doesn't filter it. The basic punchline was that the wearer of a mask, if exposed, would likely get a lower viral exposure and get a lesser infection as a result. The lesser infection would still result in immunity but would be far easier to recover from possibly even being asymptomatic. Kind of goes along with what
@NurseDave was saying about where in the airway the infection is/was only she never discussed how deep the infection might be, only the initial viral load. Sounded plausible enough even if it was total hog wash and unless people started wearing masks AND going into COVID hot zones to rescue fallen family members ors something, i don't see how it will hurt too many people to hear what she said.
I agree that as long as there is even a single person out there with the virus we are not safe. The numbers may be less but I know that I definitely don't want for any of us or our families to be among the infected...Please everyone be safe and remember this virus doesn't care it just wants to infect and until there is truly a "cure" none of us are safe... There are things we can do to try to limit our chances of catching it and I hope everyone does everything they can to stay safe.. so I pray whichever deity you pray to ( I know we have many different religions here ) will keep you safe.
I don't know is I (personally) wouldn't go so far as to say we won't be "safe" until... There are a number of big bad uglies (SARS,MERS,ZIKA,EBOLA etc) that we don't have cures for today that were pretty scary when they were the epidemic d'jour. We figure it out and move on (or forget). I am cautious and careful but to say I don't feel "safe" is not the way I (personally) would put it. I guess it is a matter of perspective, if/when any of these things are impacting you, you see it differently. (I think Nursedave said that about the schools). In my case, the shutdown and choices made that impacted access to delivery of medical care and services has had a far more negative (life altering) impact on me than the virus itself.
The exciting news in my book is that the technology we are seeing used to develop vaccines for THIS bug is ground breaking and will enable us to develop vaccines for other bad bugs and modify the COVID one as needed more quickly than our older methods. If we have to suffer the slings and arrows of the pandemic, it would be nice to get a ground-breaking technology or two out of it.
