Britain should allow the mixing of several vaccines against coronavirus under special circumstances, despite limited knowledge about whether combined doses provide the same protection or not as uniform doses.
The British government released updated guidelines on New Year’s Eve that state: “(If) the same vaccine is not available, or if the first product received is unknown, it is reasonable to offer a dose of the product available locally to complete the schedule. “
Mary Ramsay, head of immunizations at Public Health England, explained that different doses of the coronavirus vaccine would only be administered on extremely rare occasions, Reuters reported.
“Every effort should be made to give them the same vaccine, but where that is not possible, it is better to give a second dose of another vaccine than not to,” she said.
Britain was the first to provide emergency clearance for the Pfizer-BioNTech and AstraZeneca vaccines in December. Both vaccines require two doses several weeks apart, however, they were not designed to be paired, Reuters reported.
According to the guidelines released by Great Britain, there is still no “evidence on the interchangeability of COVID-19 vaccines, although studies are in progress”.
The British government also raised concerns earlier this month when it announced that it would delay administering the second doses of the coronavirus vaccine for 12 weeks to those who received the first injection in order to provide the initial injection, which provides limited protection against virus, for more people, according to Reuters.
