Who knew? A study came out way back in 2016 showing that most people still had antibodies against tetanus, or “Lockjaw” even 60 years after their last vaccination. It’s a reminder of what successful vaccination can look like. It also shows the extraordinary ability of the human immune system to acquire lifelong protection — that doesn’t happen with all diseases, but it does with things like influenza, polio, measles, and mumps, and possibly tetanus and diphtheria.

The study tested the blood of 546 people. Given the striking results the authors suggest that the need for a ten year booster should be reassessed, but six years after the study came out the CDC and the Australian government are still saying we need “ten year boosters”. Is anyone even looking at this data?

Notably, shifting to a 30 year schedule could save the US government US$280 million each year. But Big-Pharma won’t be too happy about that. It may also prevent “80–160 cases of brachial plexus neuritis” — a rare side effect.
