‘Never seen anything like this’: alarm at memo from top US vaccine official

Vinay Prasad memo said at least 10 children had died from Covid vaccination - but offered scant evidence for claim

America's top vaccines official promised, in a long and argumentative memo to staff on Friday, to revamp vaccine regulation after claiming that at least 10 children died from Covid vaccination - but he offered no evidence for that allegation and scant details on the new approach.

The top-down changes, without input from outside advisers or publication of data, worry experts who fear vaccines such as the flu shot may quickly disappear and that public trust will take a major hit.
