Flu vaccine has “only” 25 mcg Mercury. The shot is 0.5mL. Let’s do some math:
25 mcg / 0.5mL =
25 mcg / .0005L =
250,000 mcg / 5L =
50,000 mcg / L
1 mcg / L = 1 ppb, therefore
The shot has 50,000 ppb of mercury
Remember that 2 ppb mercury is the mandated limit in drinking water and normally 200 ppb would label something a toxic hazard.
Here is a table of thimerosal content in currently licensed vaccines according to the FDA.

Ingestion and Injection can be talked about later :)
As long as you are eating fish that contains more selenium than mercury, the amount of selenium in the body will always be in plentiful excess of mercury. That means that these essential selenoenzymes are never inhibited to a meaningful degree. Fortunately, the vast majority of fish most people consume have more selenium than mercury. The exceptions are pilot whale, shark, tilefish, king mackerel and swordfish.
