The 50,000 Oxford/AstraZeneca vaccines will begin rolling out to GP practices from Monday (4 January).
The GP programme will run alongside the ongoing vaccination programme and will prioritise those over 80 initially. Priority groups will be next.
The Joint Committee On Vaccination and Immunisation (JCVI) has recommended that as many people on the priority list as possible should be offered a first vaccine dose as the initial priority.
Everyone will receive their second dose to complete the course within the recommended timescale.
Chief Medical Officer Dr Michael McBride said evidence shows that the initial dose of vaccine offers as much as 70% protection against the effects of the virus.
“Providing that level of protection on a large scale will have the greatest impact on reducing mortality and hospitalisations, protecting the Health and Social Care system. It is the right thing to do for the public health.
“Everyone will of course receive their second dose to complete the course within the recommended timescale. We can all be assured by the level of protection that is available following the first dose and that the second dose will prolong the period of immunity. Within days to weeks, those vaccinated are much less likely to get severe illness.
“What we don’t know yet is whether they are at less risk of carrying the virus asymptomatically and passing it on to others. It is therefore really important that everyone who is vaccinated continues to follow the advice on social distancing, respiratory and hand hygiene and all the steps we know work in controlling infection and protecting others,” he said.
Dr McBride commended all those involved in the rollout of the vaccination programme.
He said: “I am delighted by the response by GP practices who are keen to begin the vaccination programme and I wish them all well as they begin the rollout. Members of the public will be invited to receive the vaccine by their GP, there is therefore no need for them to contact their practice.”
