10-year follow-up after a single pertussis shot
Part of Infections, Lungs & breathing clinical trials.
This study checks on people who got a single dose of a whooping cough vaccine about 10 years ago in a previous study. Researchers want to see how well the vaccine is still working and if it is still safe.
Summary written for real people, not researchers, by Clin2.
