Why do you think you're right?

2026-2030 is five years inclusive of PhD grads in microbiology and immunology.  2021-23 average is 1050, so five years is 5250.  Ph.D.s overall grew 5% 2018-2023 and 4.5% 2103-2018, biology PhDs by 9% and 1% over same periods.  Also 61% of all PhDs are U.S. citizens/green cards, 72% of bio PhDs.  Table 1.6 of resolution source.  Assuming 5% growth, you roughly get 5500 from 5250 as a base rate.

Microbiology & immunology is a mature category of bio PhDs, clocking in at 10% of the field.  While bio remains a hot scientific topic, not clear how much microbe & immunology benefits.  President Trump has proposed 40% cuts to NIH funding, but Congress is not leaning that way with no resolution of FY26 budget as of Sept 2025. https://www.brookings.edu/articles/nih-funding-and-local-employment/

The above matches with a bell curve across the 5 intervals.  Starting there, we have full year to find out if Trump really reduces NIH spending or if status quo holds.

Wildcards are US government funding of research and dissuasion of foreign students due to visa crackdowns and politics.  Within the bio field, the 10% microbiology & immunology field could become hotter or colder -- both in itself but also the competing degrees like bioinformatics might draw candidates away.
