UK Ministry of Health will allow people to be given shots of different Covid-19 vaccines on rare occasions. Mary Ramsay, head of British Public Health Department of Immunization, said this, Reuters reported.
People can be given a mix-and-match of two Covid-19 shots, for example if the same vaccine dose is out of stock.
“(If) 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,” stated in the guidelines published on New Year's Eve.
Mary Ramsay said this would only happen on extremely rare occasions, and that the government was not recommending the mixing of vaccines, which require at least two doses given several weeks apart.
“Every effort should be made to give them the same vaccine, but where this is not possible it is better to give a second dose of another vaccine than not at all,” she said.
Covid-19 has killed more 74,000 people in Britain - the second-highest death toll in Europe.
Britain became the first country to give emergency authorisation to the Pfizer/BioNTech and the AstraZeneca/University of Oxford vaccines last month.
Both vaccines are meant to be administered as two shots, given several weeks apart, but they were not designed to be mixed together.
