Researchers at Harvard have done preclinical studies which show real promise for a cheap nasal spray that could protect humans from most types of flu. The research so far has only involved mice but at that level it worked 99% of the time.
In a paper just published in the peer-reviewed academic journal Advanced Materials, the researchers say the spray “coats the nasal cavity, capturing large respiratory droplets from the air, and serving as a physical barrier against a broad spectrum of viruses and bacteria, while rapidly neutralizing them with over 99.99% effectiveness.” In other words, it catches the viruses and bacteria at the typical point of entry into our bodies — the nose — and stops them there.
There are plenty of caveats. These results came from a study involving mice, not people. The study was conducted in a laboratory, not the outside world. The spray has not gone…
