The tweak in vaccine advice, which comes as the country grapples with a new, highly contagious mutation of the virus, marks a surprising departure from previous guidance — and a starkly different approach to the vaccine rollout in the US, The New York Times reported.
The UK protocol now states that a person can receive their follow-up COVID-19 jab with a different vaccine candidate to their first dose, if necessary. Britain has approved two vaccines for the deadly bug, developed by AstraZeneca and Pfizer. The updated guidance states:
"For individuals who started the schedule and who attend for vaccination at a site where the same vaccine is not available, or if the first product received is unknown, it is reasonable to offer one dose of the locally available product to complete the schedule."However, the protocol does reiterate that receiving a second dose of the same vaccination is preferable, noting that a different inoculation should only be used if the patient is at "immediate high risk" or is considered "unlikely to attend again." "In these circumstances, as both the vaccines are based on the spike protein, it is likely the second dose will help to boost the response to the first dose," it explained.
But the new advice has still raised eyebrows in the scientific community.
