1. Pertussis, also known as whooping cough, is a communicable disease in humans. It is caused by the bacterium Bordetella pertussis, and it affects the respiratory tract. The number of cases of pertussis that were reported in Canada between 1924 and 2011 is represented in the bar graph below. Number of reported cases Reported Cases of Pertussis in Canada, 1924-2011 25000 20000 15000 10000 5000 0 1924 1934 1944 1954 1964 1974 1984 1994 2004 2009 Year a) Describe how vaccination helps prevent someone from getting pertussis. b) Based on the graph, approximately when do you think a vaccine became available in Canada? Explain your answer. c) Scientists discovered that the vaccine that was given to children between the 1980s and 1997 was not very effective. In 2003 a booster vaccination was given to those effected people. How this is reflected in the graph data?
