Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment has been made of the potential impact of repeated Covid-19 vaccine boosters on natural immunity for patients aged (a) over and (b) under 30.

Natural immunity alone provides good levels of protection against severe COVID-19, while the combination of natural and repeated vaccine-induced immunity, through initial vaccination and subsequent vaccine boosters, create ‘hybrid immunity’ which is associated with even higher levels of protection in patients aged over and under 30 years old. These high levels of strong population immunity that have developed over the past two and a half years is under regular monitoring through UK Health Security Agency public health surveillance programmes.
