"How COVID-19 is spread
COVID-19 is spread through droplets breathed out from the nose or mouth, particularly when speaking or coughing. It can also be picked up by touching your eyes, nose and mouth after contact with contaminated objects and surfaces."
Yes naomi, theres maybe a case for vaccinating key workers such as NHS staff, teachers care home staff and off course shop workers so they can avoid been off sick, before allready terminly ill older patients.
But appart from that am not sure what you mean by letting young peopel get back to work. Most shops and offices and factories, tradesman, construction sites, schools are open allready. Yes hospitality such as bars, resraunts, theatres are badly hit and employ young peopel mainly but there not able to reopen if its still spread among customers.
Hopefully by summer most will be vaccinnated and scientists will know more about spread and we can open up hospitality, concerts etc
