why is oxford AstraZeneca vaccine 90% effective with half dose,
from the video ;
due to the length of time between the dose had change the effectiveness of the vaccine, The half dose had a longer time between the 2 dose while the full dose had a shorter time.
e.g half dose , first was given 1 march the second dose with given 31 may 3 months apart.
while the full dose the first was given 1 march the second dose with given 1 April one month apart . the shorter months made the vaccine less effective
