  1. Dear Dr Cambell, I don't want to dampen your enthusiam, since it's rare to have good news coming from the pandemic. You have brought us through some terrifying days in the pandemic, but I have a question about vaccines being able to change their molecular structure. The virus for example, is in Africa and as far as I know in every country in Africa. Doesn't this all but guarantee the Coronavirus will morph into something more deadly? What if the Coronavirus mutates into something that the current batch of vaccines are not prepared to be able to eradicate? What would it take for the Coronavirus molecule to be rendered unphased by a vaccine? Thanks for doing such a great job and spending so much of your time to bring us quality videocasts. Peace
