Two observational methods are currently being used to monitor
post-deployment vaccine effectiveness against infection: the obvious crude method comparing rate of testing positive for infection per head of vaccinated population with that rate per head of unvaccinated population; and the test-negative case control (TNCC) method. The two methods give very different results. Various parties' preference for choice of method appears to broadly coincide with their vested interests in getting the result that method gives. We want to know whether either method is reliable.

We suggest how this question could be examined, and will share what conclusions we reach.
