Mixing and matching Covid vaccines could lead to more side effects, scientists say. More than 35.5million Britons have received at least one dose of a Covid vaccine and 18.4m have been fully vaccinated. The Joint Committee on Vaccination and Immunisation (JCVI) said under-40s should be given an alternative to the AstraZeneca jab due to its link to rare blood clots. The Com-COV trial, full name Comparing Covid Vaccine Schedule Combinations, is the first in the world to look at mixing coronavirus jabs. Results showed 37 of 110 people who got the AstraZeneca then Pfizer dosing regime experienced chills (33 per cent).
