Anyone over the age of 50 who received the AstraZeneca vaccine could be offered a booster.
The scheme will be available in autumn with the booster set to be made by Pfizer despite the individual having another vaccine for both doses.
It is said to be in an effort to combat the spread of the Delta variant with the Pfizer vaccine shown to be more effective at combating this variant, according to The Times.
The programme will begin next month and around 23 million people are set to be involved.
This includes those at-risk, and NHS and care home staff.
A senior government source told The Times that those who had already received the AstraZeneca vaccine, would "be getting an mRNA booster".
The Pfizer and Moderna vaccines both use mRNA to protect from covid, this allows the body to produce proteins from the virus in order to create its own immune response.
However, the AstraZeneca vaccine does not use mRNA and instead is made from a version of the common cold virus which has been modified.
The Government have said that the Pfizer vaccine is 96% effective against the Delta variant compared to the AstraZeneca vaccine, said to only be 92% effective.
In addition to these findings, it was discovered that mixing different vaccines, such as AstraZeneca for the first and Pfizer for the second, can improve an individual's chance of avoiding contracting the virus.
Currently however, there are no plans for individuals' to be offered this.
