Public Health England, scientists and doctors are advising against mixing and matching different vaccines because they work differently from each other. Pfizer second dose was supposed to be given within 21 days, Moderna and AstraZeneca second dose were supposed to be given within 28 days, but in ALL cases the government has stretched the second dose to 84 days?? Now it wants to mix and match vaccines?? Why??? There is NO shortage of supply from the manufacturers.
