Preliminary outcomes on a third coronavirus vaccine, this one from AstraZeneca and the College of Oxford, present promise. That is no much less thrilling for being the third, behind Pfizer and Moderna: The coronavirus pandemic is a problem too huge to be rapidly ended by one efficient vaccine. We’d like each attainable device towards it, and AstraZeneca’s has some key benefits.
The vaccine confirmed common 70% effectiveness throughout trials of two totally different dosages. Apparently, the much less efficient routine, at 62%, used two full doses a month aside, whereas the more practical choice, at 90%, was a half dose adopted by a full dose a month later. If that consequence holds, it might imply extra individuals being vaccinated. Importantly, it’s less expensive than both the Pfizer or Moderna vaccines, and could be saved at regular fridge temperatures, whereas the others can solely be saved at fridge temperature for a restricted time.
