"It found the vaccine, tested in a mouse model, prolonged the time before infected animals developed symptoms by up to 60 per cent.
“The vaccine doesn’t prevent the disease, but it delays its onset,” We couldn’t induce full protection, but the survival time was greatly increased.”
That doesn't sound so great to me! It means that infected animals will live longer, infecting eve more animals! I would think that a shorter life-span for an infected animal would be preferable - getting rid of to before it can infect others.
