How Do Neanderthal Genes Change Our Risk of Covid?

Humans have about 2% of Neanderthal DNA. This isn't just random DNA this is gene variants that help Homo sapiens adapt to the environment they face when they're migrating out of Africa 40,000 years ago. There's a certain variant that we can track back to Neanderthals that increases susceptibility to Covid. On the other hand we've got another variant that actually offers some protection as well so it's not a clear Neanderthal genes are bad or good in terms of Covid susceptibility.
