To all my readers:
Mole-in-the-know has informed me that Boots Dual Defence nasal spray contains an ingredient currently being tested by scientists as a chemical which may well kill the Covid virus.
Other nasal sprays do not contain this ingredient which appears to be having significant success.
£6 a throw at Boots to give you protection in shops and enclosed environments? Worth a punt.
(Mine was the last one on the shelf in Chesterfield.)
Having Taffix nasal spray to add to the vitamin D you are already using may also be a preventative. Also worth trying if in the first stages of Covid, apparently.
