A new study finds that Delta variant can grow in the noses of vaccinated people as strongly as in unvaccinated people. The virus that grows is just as infectious as that in unvaccinated people. Vaccinated people can transmit the virus and infect others.
Frequent nasal douching by nasal spray can help to clean the bacteria and viruses in the nose. Potential antiviral agents for intranasal use include Xylitol.
Xylitol forms a protective barrier in the nostrils, having an unique activity to reduce viral loads. It can be used for prophylactic regimen for antibacterial and antiviral pathogens.
