Risk Of Infection
Covid Risk of reinfection by month

This article on The Huffington Post includes an interesting graph (shown to the right) of how one's risk of reinfection with Covid-19 increases over time (from the last infection, or presumably, from the date of one's last vaccination).

This article on Salon reports on a study which shows that vaccination against Covid-19 reduces the risk of infection by only 15%!

This article on Fortune reports on the 5th wave of Covid-19 in South Africa, which was predominantly the Omicron variant, which happened even though 97% of the population had antibody protection (either from vaccination or previous infection).

Side-Effects of Covid

One of the possible side-effects of Covid-19 is type 2 diabetes (which is why I am now diabetic). Studies (e.g. this one, published on have shown that vitamin D deficiency increases the risk of serious illness from the coronavirus, and that treatment with vitamin D supplements can reduce the severity and duration of illness. This report on by Medical News Today looks into the use of vitamin D supplements for treating type 2 diabetes; although the results of studies are mixed, it suggests to me that the coronavirus may interfere with the body's vitamin D metabolism to cause type 2 diabetes.

Also on Medical News Today is this report which suggests (a causative link has not yet been proven) that Covid-19 can cause long-term (maybe even permanent) thyroid dysfunction, which could cause a wide range of knock-on health effects.
