Question to the Department of Health and Social Care:

To ask His Majesty's Government what plans they have to maintain a vaccine-based immunity in the under-65s given the spread of the JN.1 COVID-19 sub-variant.

The Joint Committee on Vaccination and Immunisation (JCVI), a body of independent experts, advises the Government on who should be offered vaccination through the national programme for COVID-19. JCVI advice continues to be aimed at reducing hospitalisation and mortality in those groups which are at higher risk of serious outcomes from the disease.

Throughout the pandemic, older people have been amongst those most likely to experience severe disease if infected by SARS-CoV-2. Existing data on hospital admissions in the United Kingdom is consistent with the clinical risk continuing to be strongly age related, as well as associated with specified existing clinical conditions.

The JCVI view based on the available data is that due to a combination of naturally acquired and vaccine derived immunity in the population, otherwise known as hybrid immunity, COVID-19 is now a relatively mild disease for most people. This is why JCVI advice to date is that the COVID-19 national programme should be targeted to those at higher risk of developing serious COVID-19 disease. More information regarding current eligibility for seasonal vaccination is available in chapter 14a of the Green Book, a copy of which is attached.

The JCVI continues to regularly review the emerging data on COVID-19 for each new campaign they recommend.
