Covid, Flu and RSV Protection Protocol
While flu and RSV infections were uncommon in 2020 and 2021, a dramatic increase in infections was documented in the fall and early winter of 2022. We have therefore adapted I-PREVENT to include prevention against flu and RSV. It should be noted that the medications in I-PREVENT are inexpensive, safe, and widely available.
This protocol includes a section on how to prevent infection before you’ve been exposed (pre-exposure/long term) as well as how to prevent infection if you have potentially been exposed (post-exposure/acute, short-term).
At the onset of flu-like symptoms please refer to the I-CARE: Early COVID Treatment or I-CARE: RSV and Flu Treatment Protocols.
Learn about nutritional therapeutics and how they can help with COVID-19.

How to prevent infection before you’ve been exposed
Table 1. Guidance on Upfront Loading Dose Regimens to Replenish Vitamin D Stores in the Body
When serum vitamin D levels are available, the doses provided in this table can be used for the longer-term maintenance of serum 25(OH)D concentration above 50 ng/mL (125 nmol/L). The table provides the initial bolus dose, weekly dose, frequency, and the duration of administration of oral vitamin D in non-emergency situations, in a non-obese, 70 kg adult. *
|Baseline Vitamin D
|Vitamin D dose, 50,000 IU capsules:
Initial and weekly $
(Number of Weeks)
|Total Amount Needed to
Correct Vit. D,

|Initial Bolus Dose (IU)||Follow-Up: $$
The Number of 50,000 IU Caps/Week
|< 10||300,000||x 3||8 to 10||1.5 to 1.8|
|11-15||200,000||x 2||8 to 10||1.0 to 1.2|
|16-20||200,000||x 2||6 to 8||0.8 to 1.0|
|21-30||100,000||x 2||4 to 6||0.5 to 0.7|
|31-40||100,000||x 2||2 to 4||0.3 to 0.5|
|41-50||100,000||x 1||2 to 4||0.2 to 0.3|
* A suitable daily or weekly maintenance dose to be started after completing the loading-dose schedule. The dose should be adjusted for those who are overweight (higher) or underweight (lower).
** To convert ng/mL to nmol/L, multiply the amount in ng by 2.5; One µg = 40 IU.
$ Mentioned replacement doses can be taken as single, cumulative doses, two to three times a week spread out over a few weeks.
$$ From the day one of week two onwards.
# Estimated total Vitamin D dose needed to replenish the body stores (i.e., the deficit) is provided in the last column.

Table 2. Vitamin D Dosing in the Absence of a Baseline Vitamin D Level
Longer-term maintenance schedules of oral vitamin D based on body weight to maintain the levels above 50 ng/mL (125 nmol/L) when the serum 25(OH)D concentrations are unknown.

* Example of a daily or once-a-week dose range for adults with specific body types (based on BMI for white Caucasians and body weight for other ethnic groups). Appropriate dose reductions are necessary for children.
# For those with chronic comorbid conditions, such as hypertension, diabetes, asthma, COPD, CKD, depression, and osteoporosis, and to reduce all-cause mortality, higher doses of vitamin D are needed. For them, one can use the doses that are recommended for persons with obesity (BMI, 30–39: the third row).
$ Those with multiple sclerosis, cancer, migraine headaches, and psoriasis, and those routinely taking medications such as anti-epileptic and anti-retroviral agents that significantly increase the catabolism of vitamin D should consider taking age-appropriate doses recommended for those with morbid obesity (BMI ≥ 40; the higher end of the daily doses in the fourth row).

Table 3. How to calculate ivermectin dose
Note that ivermectin is available in different strengths (e.g., 3, 6 or 12 mg) and administration forms (tablets, capsules, drops, etc.). Note that tablets can be halved for more accurate dosing, while capsules cannot.
