I used the second dose. For all doses, a positive correlation coefficient is found for certain time shifts. However, because monthly data was used, the significance of the correlation coefficient for the boosters was not sufficiently high enough. As indicated, I would have preferred weekly data, plus a different method. Unfortunately I do not have a lot of time.
All are using the time of the 2nd dose right? So there would be a negative time shift if a person dies after 1st dose, but before 2nd?
