Push to roll out injections may see elderly miss out on effective coronavirus inoculations
Scientists have warned that early adoption of a Covid vaccine with only moderate effectiveness could disrupt efforts to test and create improved versions. Immunising against the disease is not going to be a simple business of turning off the virus once the first vaccine appears, they say. In fact, there could be considerable confusion as researchers struggle to pinpoint the best versions for different vulnerable groups, such as the elderly.
“The vaccines coming through fastest are the most experimental. It is possible they won’t be all that great and that others – created using more tried-and-tested but slower methods – might be better,” said Professor Adam Finn of Bristol University. “But to prove that point will become very difficult if lots of individuals have already been given the first vaccine. It will need vast numbers of people to demonstrate which is best or if a different vaccine is more suitable for particular groups, like the elderly.”
