A recent study is trying to discover how effective mixing two vaccines will be. The experiment supported by the UK government is expected to come out with its finding before summer 2020.
Mixing two vaccines could give better protection - Health experts
A UK trial has started research to see if administering vaccines of different developers on volunteers for doses can be as effective as sticking to one vaccine. This experiment aims to offer better flexibility with the many vaccines rolled - out and help augment shortages experienced with some vaccines.
Infectious disease experts have even suggested that mixing vaccine doses may give better defense against the virus. However, the UK vaccine minister has insisted that the current approach by the government won't tamper with at least August. As of today, the official policy from the Joint Committee on Vaccines and immunity says anyone administered with either the AstraZeneca or Pfizer jab should be given the same vaccine for the second dose.
The UK sticking with its present vaccination policy
The UK approach will change on vaccines except on rare occasions cases where only one vaccine is available and the recipient cannot wait for the unavailable ones. Minister Nadhim Zahawi stated that the UK government has contributed about £8 million in support of this study.
However, the results will not be shown till the summer, so there isn't hope that a policy change is possible. Mixing vaccines is not a new thing as it has been done for Ebola disease when vaccines are mixed for better protection. According to other health sources, this has also been done for Polio, measles, and Hepatitis. This research will be run by the National immunization schedule Evaluation commission and already has about 850 volunteers.
It will recruit only volunteers within the age of 50-75 and will only recruit volunteers from Bristol, London, Birmingham, and Manchester. They will first be given a jab of Pfizer before administering the AstraZeneca vaccine to see results.
