"...experts say that people with healthy levels have no need of vitamin D supplements – which would be most people. In other words, they argue that in healthy people, vitamin D is not, as some have hoped, a way to prevent disease.
...
The current guidelines on how much vitamin D to take were informed by research involving the elderly population living in care homes, who don’t get as much exposure to the sun and are more prone to fractures and osteoporosis than the general population. But Tim Spector, professor of genetic epidemiology at King's College London, has argued that such studies are “probably flawed”.
It’s true that the evidence isn’t clear-cut. One meta-analysis published in August 2018 concluded that increasing the levels of vitamin D in the general population is unlikely to decrease the risk of bone fractures in healthy people. And a meta-analysis of 81 studies found that vitamin D supplementation doesn’t prevent fractures or falls, or improve bone mineral density. The researchers concluded that guidelines should be updated to reflect this.
...
One meta-analysis concluded that more research is needed to clarify the effect of vitamin D on mortality. The link between cardiovascular disease and vitamin D also has yet been properly established: the link could mean that heart disease is causing low vitamin D levels, not the other way around.
...
Other studies, including of the link between vitamin D and liver cancer, breast cancer and prostate cancer, suggest there is good reason to think that low vitamin D plays a part in the spread of cancer cells. But taking supplements would then, surely, help stave off cancer – and a recent meta-analysis failed to find that supplementation reduced cancer risk.
...
Some scientists argue that getting vitamin D from supplements isn’t as effective as getting it straight from the sun, as the process that happens before the body makes vitamin D from sun exposure is more beneficial. More conclusive research around this is currently underway.
...
some studies suggest too much vitamin D can increase risk of cardiovascular disease

As part of my attempt to balance and offset the huge one-sided biased hype in favor of the idea we all take vit D pills that normally ignores all the studies and evidence against doing that, here above I only picked those parts of this link that seem to go AGAINST the idea we should all be taking some vit D pills while leaving out those parts that hint of the contrary. If you point out and accuse me of doing the latter, you are totally missing my point. My point is that the evidence is currently conflicting and it is far too soon to conclude with any certainty that we should all take vit D pills. I'm NOT claiming we shouldn't take vit D pills but rather, except for people that are obviously vit D deficient, claiming it is too soon to tell.
Interesting study on longer term consequences of COVID-19
