Blood Test Anomalies After Moderna Booster

Since my booster shot in October 2021, two routine blood tests have picked up high absolute lymphocytes, high RDW, low hemoglobin and low hematocrit. The RDW, hemoglobin and hematocrit are just outside the normal range but the lymphocytes are quite high (although down from the first blood test). I know there are many reasons for all of the above but the only major change in my health since 2021 has been getting the Covid vaccine. It's possible I had an early case of Covid in 2020 when I was in Australia. I am otherwise quite healthy. My iron levels are normal. Has anyone else seen changes in their routine blood tests that might be Covid related? Thanks.
