A clinical study to determine whether an alkaline barrier created in the oropharynx by use of spray containing 8.4% sodium bicarbonate can mitigate development of Influenza Like Illness (ILI) and Covid-19 infection.

A prospective, double arm, placebo control, single blinded, investigator led research to study the barrier strength of the aerosol against the development of Influenza Like Illness (ILI) including Covid-19 infection in the general as well as high risk population and to assess the safety and tolerability of an aerosol having as its active ingredient 8.4% sodium bicarbonate when administered to the oropharynx.
