Covid-booster response hope for most vulnerable

More than a million vulnerable people could improve their protection against Covid by taking a short break from medication after a booster jab, a trial suggests. It found stopping the common immune-suppressing drug methotrexate for two weeks doubled spike antibody levels for up to 12 weeks. Some people experienced disease flare-ups but no impact on quality of life. Research is needed to find out if a similar approach works for other drugs. Patients should always consult their doctor or specialist hospital team before pausing their medication, scientists writing in the Lancet Respiratory Medicine said.
