What difference does it make when you get your second AstraZeneca jab? | Smh.au |

The Delta variant has acquired mutations that slightly change the shape of its spike protein - the microscopic harpoon it uses to enter our cells - meaning some antibodies that would have gummed up earlier variants slide right off Delta. These changes appear to significantly cut the effectiveness of both AstraZeneca and Pfizer's vaccines. Those drop-offs in effectiveness are most pronounced after a single dose of either vaccine.
