What is this exactly supposed to mean?
There is no vaccination for RSV where I live so the only way to get it is via child care or other contacts with toddlers.
- carlivar 4y agoTo quote this article, "extended periods of low exposure to a particular pathogen." https://www.thelancet.com/journals/lanchi/article/PIIS2352-4642(21)00333-3/fulltext https://www.thelancet.com/journals/lanchi/article/PIIS2352-4... As I understand it, just being out and about in the world gives an immune system (whether a baby or its family members indirectly) some practice.

- carlivar 4y agoI'm not sure about fine. Probably just undiagnosed? According to this, RSV kills 100k babies and kids between 0-5 per year. 97% of them are in low and middle income countries. https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)00478-0/fulltext https://www.thelancet.com/journals/lancet/article/PIIS0140-6...
- graeme 4y agoWell, this paper suggests I’m wrong and that lower and middle income countries get more infections and more death. So….why again would avoiding infections be bad? The added infections appear to increase deaths.
- argonaut 4y agoThe article mentions that mothers give toddlers antibodies from exposure to viruses during pregnancy.
- chinathrow 4y agoI do not understand the term "immunity debt". What is this?
