I was surprised the #AstraZeneca vaccine doesn’t give partial protection until Day 22 after the first jab - I think Pfizer was Day 7 partial protection after first jab. Lockdowns and continued diligence will be with us for a long, long time

They are different technical approaches & the AZ vaccine is only 62% effective after two doses. It seems to be less effective than the Pfizer vaccine in provoking the desired immune counter-response at every stage but it is much easier to handle, distribute & give.

Yep. It will certainly help to get more people vaccinated & reduce mortality rates if it works well in highest risk groups (tbd in real world) but 62% efficacy whilst not terrible for a new vaccine does make full community immunity harder to achieve than eg 95% efficacy
