HUNDREDS of thousands of those most at risk from Covid have yet to come forward for the latest booster jab.
NHS England said two thirds of those with a weakened immune system had been vaccinated.
But it thinks others may not be aware they have a condition making them eligible for a top-up.
They include pregnant women and people with diabetes, epilepsy, blood cancer and asthma.
They are among those at greater risk of becoming seriously ill or needing hospital treatment if they catch Covid.
NHS director Professor Sir Stephen Powis said: “We know that there are hundreds of thousands of people out there who are at increased risk but are yet to come forward.”
More than 16 million people have had a Covid booster while 18 million have had the flu jab.
