1 Which of the following statements is correct?

• Giving critically ill COVID-19 patients high doses of vitamin D significantly reduces the number of days they spend in the ICU

• Giving critically ill COVID-19 patients high doses of vitamin D has no impact on the length of hospitalization
• There's no evidence vitamin D impacts COVID-19 outcomes
• Evidence shows 100% of COVID-19 cases can be avoided with a vitamin D level of 60 ng/mL

2 To create the vaccine-acquired herd immunity required to end the pandemic, COVID-19 vaccines must be able to:

• Minimize symptoms of infection
• Reduce risk of infection

  To create the vaccine-acquired herd immunity required to end the pandemic, COVID-19 vaccines must actually reduce the risk of infection. Learn more.

• Increase asymptomatic cases
• Increase the risk of infection

3 Which of the following appears to play an important role in COVID-19, influencing COVID-19-specific disease processes such as viral replication and invasion, cytokine storm induction, adaptive immunity and hypercoagulability?

• Vitamin A
• Vitamin K, K2 in particular
• B vitamins, niacin (B3) in particular

  B vitamins can influence several COVID-19-specific disease processes, including viral replication and invasion, cytokine storm induction, adaptive immunity and hypercoagulability. Niacin appears particularly important. According to a recent paper, there appears to be a causative link between low niacin status and SARS-CoV-2 infection. Learn more.

• Vitamin D2 specifically

4 Compared to wild-caught salmon, farmed salmon contains:

• Higher amounts of omega-3 and lower amounts of omega-6
• The same ratios of fats and vitamins as wild-caught salmon
• Healthier ratios of omega-3 to omega-6
• Higher amounts of omega-6 and lower amounts of omega-3 and vitamin D

  Farmed salmon have the nutritional drawbacks of containing only half the omega-3 of wild salmon and four to eight times less vitamin D, while having more than 5.5 times the amount of harmful omega-6. Learn more.
