To ask the Secretary of State for Health and Social Care, what recent assessment his Department has made of the potential risk of people with partial trisomy experiencing heart complications following an mRNA vaccine; and if his Department will take steps to ensure that the decision of Mr Justice Hayden in the Court of Protection is communicated to all health service professionals.

There has been no formal review of the potential risk of people with partial trisomy experiencing heart complications following an mRNA vaccine, although the safety of vaccines is continually monitored by the independent Medicine and Healthcare products Regulatory Agency (MHRA). The MHRA conducted detailed analysis of all Yellow Card reports of heart inflammation, specifically myocarditis and pericarditis, which occurred following an mRNA vaccine. Details of these analyses were published weekly in the MHRA’s Coronavirus Vaccine - Summary of Yellow Card Reporting, which is available at the following link:

These analyses did not identify a specific safety concern in relation to patients with congenital conditions, such as trisomy, who received an mRNA vaccine.

In relation to the judgement of the Hon. Mr Justice Hayden, there are currently no plans to communicate the decision from this specific case to all healthcare professionals. As with all vaccines, should any information indicate a possible new safety concern, the system is well placed to rapidly and thoroughly investigate this, with advice for healthcare professionals and patients updated where appropriate.
