2911. Deputy Denis Naughten asked the Minister for Health if there are plans to allow for mixing of Covid-19 vaccines between first and second doses; the options available to those advised not to obtain a second dose of the same vaccine due to an adverse reaction; and if he will make a statement on the matter.

View answerIreland’s COVID-19 vaccination programme strategy is to distribute all available vaccines as quickly as is operationally possible, prioritising those who are most vulnerable to COVID-19. The programme is based on the principles of safety, effectiveness and fairness, with the objective of reducing severe illness, hospitalisations and deaths from COVID-19 infection.
The immunisation programme in Ireland is based on the advice of the National Immunisation Advisory Committee (NIAC). The Committee's recommendations are based on the prevalence of the relevant disease in Ireland and international best practices in relation to immunisation. It makes recommendations on vaccination policy to my Department.
The NIAC review all data relating to COVID-19 vaccines on a rolling basis. Following the recommendation for use of vaccines against COVID-19 by the European Medicines Agency (EMA) and authorisation for use by the European Commission, the NIAC develops guidance for their use in Ireland which is contained in the Immunisation Guidelines for Ireland.
These guidelines are continuously updated and include guidance on all new vaccines as they are approved for use in Ireland. The current Guidelines state the four COVID-19 Vaccines currently authorised for use in Ireland are not interchangeable. For vaccines that have a two-dose schedule, the same vaccine should be used for both doses.

There is insufficient evidence to recommend a change from the authorised two-dose Vaxzevria® schedule or to support giving an mRNA vaccine instead of a second dose of Vaxzevria®. There is a need for further evidence on the safety and effectiveness of mixed (heterologous) vaccine schedules. Further information is expected in the coming months which may warrant an update of these recommendations.
