My first husband was a virologist. He worked for a University in a hospital laboratory. He started up the Virus Lab in Aberdeen. He used to talk about corona viruses regularly - they are all inter-related.
I clearly remember him complaining bitterly about all the red tape involved in having vaccines and treatments approved. He said a lot more lives could be saved across the world if all the governments got together and agreed on standards. Some of them have done that and that is why these four or five vaccines have been approved so quickly,
Every vaccine that is created in a laboratory is tested and tested till its eyes water - believe me. I remember him talking of little else when he found a new virus, and a new antidote
So, on a personal level, I have immense faith in the people he trained, and in those who they themselves trained up to his high standards. I wish he were still alive, not just for personal reasons, but so that he and Professor Pennington (Hugh to us) could yet again put the world to rights
Like any other virus, and indeed bacteria, it will become immune to the vaccine unless the majority of the population is vaccinated quickly. Remember the story about antibiotics? Finish the course! Even so, ABs are becoming less effective due to overuse. So let's get this done and let it be a one off till the next new virus hits us.
