How long is whooping cough injections effective for? i had mine while pregnant about 1 year ago, am i still protected?

Should be: If you completed the primary whooping cough (pertussis) series at some point, this as a booster should provide 10 yrs of protection. We are still analyzing data on adult use of the shot, which was not done routinely until after the year 2005, but current recommendations replace the older Td booster with TdaP every 10 yrs as the proper way to best protect yourself and others,

Yes but: Immunity seems to wane some say 2 some say 5y. As a precaution therefore we tend to now give pregnant women a booster shot between 28-38 weeks each pregnancy
