NCT05447065

Brief Summary

Decreased immunity in individuals causes a decrease in vaccine response, and vitamin D worsens this course. Vitamin D is thought to be a vitamin that can strengthen the innate immune response, inhibit the adaptive system, and modulate the vaccine response. The effect of vitamin D intake on antibodies was studied.

Outcome Measures

Primary Outcomes (1)

  • From the first measurement, 2 more measurements were taken, 28 days apart, and a total of 3 blood measurements were taken from the participants. Antibody levels were measured with the fluorescent immunological (FIA) method.

    Compared to other coronaviruses, it was understood that there is an instant need for a vaccine to prevent SARS CoV-2 because of its faster transmission. However, it is very important to determine that the COVID-19 vaccine is immune to individuals, and it has been emphasized that Immunoglobulin G (IgG) levels are checked for immune testing and it is important that these levels are high. People's immune systems or nutritional levels are influential in the high rate or efficiency of immunoglobin levels Studies have reported that individuals with adequate and balanced nutrition have a stronger immune system

    Within research completion, an average of 8 week

Secondary Outcomes (1)

  • From the first measurement, 2 more measurements were taken, 28 days apart, and a total of 3 blood measurements were taken from the participants. 25(OH) Vitamin D level levels were measured with the fluorescent immunological (FIA) method.

    Within research completion, an average of 8 week

Study Arms (2)

Participants using vitamin D supplements

EXPERIMENTAL

Participants in the experimental group were given 150,000 IU (10 ml) of vitamin D3 supplementation, and it was used regularly for 2 months. From the first measurement, 2 more measurements were taken, 28 days apart, and a total of 3 measurements were taken from the participants.

Dietary Supplement: Vitamin D supplement

Participants not using vitamin D supplements

NO INTERVENTION

No supplement was given to the control group. From the first measurement, 2 more measurements were taken, 28 days apart, and a total of 3 measurements were taken from the participants.

Interventions
