Unfortunately, we have reason to believe that over time, the immune defenses from COVID-19 infection seem to decline, particularly in older folks. It'd be great if we had some definitive data on secondary infection rates, but until a lot more people get infected, we just won't have it.
- barney54 5y agoWhat is the evidence that “we have reason to believe that over time, immune defenses from COVID-19 infection seems to decline”?
- astrange 5y agoI think this is another case where improved surveillance is turning up things that, while they look bad, happen with other vaccines and never turn out to be a problem. The same goes for variants, which a lot of people expect to break through vaccines because that's how the flu works, but it doesn't actually seem like they will.
- jkhdigital 5y agoYes, the extreme focus of attention is turning routine and expected medical observations into scary anecdotal news cycles.
- huffmsa 5y agoI keep hearing this, but have yet to see evidence that the elderly are catching second rounds at a high rate.
- garmaine 5y agoBecause there isn’t any. But that is how the aging immune system responds to most other diseases, so we assume the same will be true here.
