Mixing Covid vaccines could mean booster jab is not needed, says professor

Mixing vaccines may give such strong protection against Covid-19 — including variants — that a booster jab is not needed in the autumn, a leading medical expert said today. Sir John Bell, Regius Professor of Medicine at Oxford University and a member of the UK’s Vaccine Taskforce, stressed that research being led by his colleague Professor Matthew Snape may deliver another breakthrough in the battle against coronavirus. “The work that Matthew Snape and others are doing in this study to look at comparisons may give us a mix that actually gives us some better immune response that means we are better able to deal with the South Africa variant, the Brazilian variant, and dozens of other variants that are now popping up all over the world,” he told Sky News.
