What’s slowing it down - supply / organisation/ reluctance
Infection (with infections in the target group running in the thousands / 100,000 at the moment, a very large number of supposedly eligible children are within 28 days of infection)
Organisation (and infection of vaccinators). Delivery through schools rather than the tried and tested mass vaccination centres has been slow, cumbersome and fraught with supply issues of personnel and vaccine.
Supply (of people). Infection of vaccinators and in their children, as well as numbers of infected people needing NhS staff in their normal posts has severely limited the number of vaccinators available.
Had we done this in the low point of infection in the summer, like other countries did, then the picture would be entirely different.
