US agencies are dedicating more funds to study "long Covid" disabilities, now that tens of millions of Americans may have them.

The easiest way to deal with the problem of these disabilities is to prevent them. Effective measures to prevent transmission of Covid-19 will mean that fewer people catch it, and fewer people get disabled in this way.

One thing I have not seen is reports about what fraction of people that catch Delta get long Covid. What about Omicron? What about fully vaccinated people?
