From the BBC:
Local MP Liam Byrne spoke about the problem in the House of Commons this week. It is, he told MPs, "a story of two nations - rich and poor".
This is not unique to Birmingham. It is a pattern that is being repeated across the country. The people who are most at risk from the virus are the ones, it seems, who are least likely to come forward for vaccination.
Detailed data on uptake down to a community level is not being published by the government to the frustration of many - the figures for Birmingham were published by the council. But what information is available suggests the poorest and most ethnically diverse communities (there is a huge overlap between the two) are seeing the lowest levels of uptake.
