Summary

This completed study tracked over 10,000 people in Thailand who received the Boostagen® vaccine, which protects against tetanus, diphtheria, and whooping cough. Healthcare workers reported any side effects to see how safe the vaccine is in everyday use. The study also looked at pregnant women and their newborns to check for any complications. The goal is to ensure the vaccine remains safe after being approved for the public.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Boostagen® (combined tetanus, diphtheria, and acellular pertussis vaccine)
What this could lead to
If successful, this study will confirm that Boostagen® is safe for widespread use, including in pregnant women, helping protect against whooping cough, tetanus, and diphtheria.
What could go wrong
This is an observational safety study, not a test of effectiveness. It may not detect rare side effects, and results are specific to Thailand's population.
