Hoppy,
You're correct! Vitamin D3 is very important as a preventative for cluster headache and for a healthy immune system.

The following graphics come from the study of the anti-inflammatory regimen that's been running for nearly 10 years. The before and after normal distribution curves of 25(OH)D3 lab results from the 320 participants tell the story as does the third graphic illustrating favorable responses to this regimen.

That said, the ice is a lot thicker than you think. While it's true there are several studies concluding vitamin D3 helps reduce the frequency of viral infections like colds and flu, as of February of this year, there were no published RCT results or case studies of vitamin D3, Vitamin C (ascorbic acid) and/or vitamin B1 (Thiamine) being use to treat COVID-19.
All that has changed. The vitamin B, Vitamin C and vitamin D3 genies are out of the bottle as a result of their use in treating COVID-19 in the ER and in several studies. This has Big Pharmas and their acolytes running around with their knickers in a wad. There's so much positive information (medical evidence) already coming out of existing studies using vitamin B1 (Thiamine), Vitamin C (Ascorbic Acid) and Vitamin D3 (Cholecalciferol) as interventions for COVID-19 that Big Pharma will never be able to get these vitamin genies back in the bottle.
As of 22 July 2020, there were 20 RCTs using vitamin D3 as the intervention for COVID-19 and 3 studies where vitamin D3 is being used as the preventative. See the following link for details and a whole lot more on vitamin D3 and COVID-19.

Of course Traveller will likely pitch a hissy fit because Mercola is listed at least a half dozen times in the hundreds of links at the above VitaminDWiki web page. He thinks nothing of walking on my first amendment rights with comments in this thread bordering on defamation and libel, but then as the self appointed thought police, he thinks its okay to render his form of censorship. Bottom line, Traveller is unable and unwilling to enter an open debate in this forum on the merits of taking vitamin D3 and its cofactors as an immune boosting strategy to help prevent viral infections.
Getting back to the context you mentioned... I'm not a doctor so I do not diagnose, I don't prescribe, I don't treat, and I don't recommend any course of treatment. I'm just the messenger. What I do is provide the best information available on the benefits of vitamin D3 and its cofactors in preventing CH and more recently the benefits of vitamin C, vitamin B1, zinc and quercetin. I leave any actions up to the reader and their PCP/GP or neurologists so they can do their own risk benefit analysis, then take action accordingly.
On the topic of risk benefit analysis, a review of the FDA's Adverse Events Reporting System (FAERS) that's been running since Jan 1997 has some interesting data. I did queries where the subject intervention was the primary suspect resulting in Death since Jan 1997. I've also provided links to these query results. As you will see in the case of vitamins, there were other drugs involved and in most cases, the vitamin interventions were given to patients with existing serious medical conditions.

Bottom line... The way I see it, there is no downside to taking the above vitamins and minerals as by any measure, their safety profile at the doses we take to prevent CH is excellent with no harms. Moreover, the upside potential for a reduction in rate of viral infection by taking these vitamins and minerals is good.
Accordingly, readers have two choices. They can do nothing more that follow the CDC's passive COVID-19 measures of hand and face hygiene, masks, social distancing and hunker in place taking their chances of avoiding a COVID-19 infection while they wait for a vaccine that may or many not be effective, OR... they can play a safe, be proactive and take the immune boosting anti-viral vitamins and minerals. They can do this at home. No Rx required.
It's anecdotal at this point, but I've gone out to several CHers who have been taking the anti-
inflammatory regimen for more than a few months on the topic of COVID-19. All reported a significant reduction in flu infections and none have experienced a COVID-19 infection as far as they know.

I tested negative for the COVID-19 RT-PCR assay in early June in preparation for a fishing trip to Pelican, Alaska. I'm scheduled for another COVID-19 RT-PCR lab test tomorrow in preparation for the annual Batcheller Family Salmon Fishing Derby in Ketchikan, AK that starts on Saturday. I'll keep you posted.
On the topic of COVID-19 vaccines, the link below will take you to a fascinating and illuminating discussion on youtube between Robert F. Kennedy, Jr. and Alan Dershowitz on COVID-19 vaccines.
