Only private jabs are available to most, but annual shots could reduce healthcare costs and prevent deaths

Private Covid boosters are available for people who do not qualify to receive these vaccines on the NHS. But is it worth paying for a shot?

With most people now having been exposed to Sars-CoV-2 through previous vaccination and/or infection, our immune systems are generally well equipped to recognise and kill the virus if we become infected.

Even so, unless we’ve recently been infected or received a booster, the number of antibodies circulating in our blood is likely to be low.
