A booster Covid jab may be needed in the future, but recent research on immunity levels is promising, an expert has said.
Dr Mike Tildesley, a member of the Scientific Pandemic Influenza Group on Modelling (Spi-M) which advises the Government, told Times Radio that a recent report on results from the Zoe app suggested that six months after vaccination immunity levels dropped but this was “not significant”.
Speaking in a personal capacity, he said: “We do need to remember that no vaccine is really 100% protective forever, or the vast majority are not.
“We have this with influenza, that every year you have to have a vaccine to protect against whatever’s circulating.
“So we might expect in the long term immunity will wane and there may be a need for a booster vaccine.
“But actually, I think what’s come out this week is pretty promising that immunity levels seem to remain high for several months, which is hopefully promising as we move into the winter.”
