4. Conclusion
Much progress has been achieved to elucidate the multifaceted function
of lactoferrin (Lf) in the past 30 years as an antiviral as well as a
unique anti-inflammatory and immunomodulatory molecule. We have
presented the experimental as well as clinical rationale for its use for
COVID-19, but further experiments to verify its inhibition of the virus
and clinical trials to elucidate dosage and efficacy are necessary to
confirm the potential of Lf for SAR-CoV-2 prevention as well as COVID-19
treatment.
