Grassroots Health points to a 2017 paper that identifies 100 nmol/L as a healthy target value. See How Much is Too Much Vitamin D? - GrassrootsHealth The actual paper is available at https://www.tandfonline.com/doi/full/10.1080/19381980.2017.1300213

Readers know that there are lots of different influenza viruses, including some that do not infect humans. Genetically modifying these viruses to increase range of species they can affect is quite controversial: EXCLUSIVE: Controversial experiments that could make bird flu more risky poised to resume | Science | AAAS
As I recall he said "science fiction movies are not substitutes for professional medical advice" Will not shrink the first yell. It seems potentially important
no need to yell. i don't remember that one. but i do recall some kind of theory he had about life. perhaps not applicable here, but some scientists in the article do seem concerned about keeping this stuff contained in the lab.
One important thing about (i.e., viral) genetic engineering is that it has become technically feasible at low cost and middling skill levels. Even if well-funded research follows all the rules, publications can contain important information for hackers. As mentioned earlier, influenza viruses are already very good at self engineering. One lacking human infectivity has a plausible chance to "ah, find a way". Over 200 (or 300) thousand years of humans, some flu species have not done this. But now there are so many more and living in close proximity. Defending against new risks can be helped by cautious genetic engineering. There's the controversy in a nutshell.
It turns out that this is also a hot topic for Russians sowing disinformation, distrust, and amplifying discord. The human trolls play up both side at the same time. KOMO-Seattle: Russian trolls, bots influencing discord in immunization debate, study finds American Journal of Public Health (AJPH): Weaponized Health Communication: Twitter Bots and Russian Trolls Amplify the Vaccine Debate "Conclusions. Whereas bots that spread malware and unsolicited content disseminated antivaccine messages, Russian trolls promoted discord. Accounts masquerading as legitimate users create false equivalency, eroding public consensus on vaccination."
The χ2 (chi-squared) test . Always have to go back and re-educate myself on that one. Yeah, hard to understand a nation expending so much energy on internal and external discord - like a malicious kid on the playground that offers little team building to his schoolmates, but to exist and maintain significance must have enemies and play the role of disruptor. Sorry to hear the Russian trolls get into this sphere as well.

Notion of recreating extinct species ought to deserve a separate discussion. Access to unperturbed, particular paleo-DNA is important. Parthenogenesis (making babies without sexual exchange) is also important. Other things also. First resurrected species (if they are done) won't be 65 million-year-old dinos, they will be from -10,000 years and they are feasible because sister species persist. Mammoths may be done, even though I don't see their value other than as zoo attractions. Dinosaurs would surely be better zoo attractions but their particular DNA is not available. Mosquitoes preserved in amber harvested blood broadly. At best they provide a muddle. Unmuddling that is beyond current skills. In no way should my words diminish Crichtons' writing or subsequent movies. Science fiction glides past details, and confronts relatable people with fictional problems. We enjoy their responses and those get monetized.
