Probably waiting until nearly everyone has had it.
Even though Hancock says that the vaccine might not work against a different varient..
Even though astrazeneca say:
AstraZeneca has confirmed 100% protection against severe disease, hospitalization and death in their primary analysis of Phase III trials more than 22 days after the first dose. The trials were done in the UK, Brazil AND South Africa.
You know Hancock, where the south Africa variant is much more prevalent? The one that he keeps banging on about ...saying that the vaccine might not work..shameless human being
