Scientists have created a vaccine that has the potential to protect against a broad range of coronaviruses, including varieties that are not yet even known about.
The vaccine is made by attaching harmless proteins from different coronaviruses to minuscule nanoparticles that are then injected to prime the body’s defences to fight the viruses should they ever invade. “We’ve shown that a relatively simple vaccine can still provide a scattershot response across a range of different viruses,” said Rory Hills, a graduate researcher at the University of Cambridge and first author of the report. “It takes us one step forward towards our goal of creating vaccines before a pandemic has even started.”
Medical regulators do not have procedures for proactive vaccinology and the researchers say these would have to be worked out with the relevant bodies. If the vaccine were found to be safe and effective in humans, one option would be to use it as a Covid booster with the added benefit of it protecting against other coronaviruses.
