The budgets for NIH and CDC are proposed sometime early in the year, around this time. IInterest groups make recommendations on changes that should be made, and these may or may not be implemented over the year. For example, for CDC, in spring last year, CFS funding got zeroed, and activism was not successful in changing it like it was the year before. They then go into force the next year, with usually limited changes. The publicised proposals to slash the budget of the NIH mean that it is likely the budgets for CFS may be under threat. https://www.cdc.gov/budget/congressional-justification.html https://officeofbudget.od.nih.gov/history.html Currently only the 2017 budget is up.
