Get a TDaP booster if it's been more than five years and extra especially if it's been more than ten years! Pertussis (whooping cough) immunity wears off over time and it's currently circulating again! You do not want whooping cough!
For the curious:
www.cdc.gov/pertussis/si...
"One to 2 weeks after the first symptoms start, people may develop ... coughing fits. These ... usually last 1 to 6 weeks but can last for up to 10 weeks.
The cough generally gets worse and becomes more common as the illness continues."
