Vaccination is used to limit the spread of transmissible diseases. The MMR vaccine is administered to young children and gives immunity against a disease known as measles. The graph displays the percentage of a country’s population vaccinated with the MMR vaccine and the number of measles cases over time. Which statement is supported by the data?
- AEach year, the percentage of the population vaccinated using the MMR vaccine decreases and the number of measles cases increases.
- BThe percentage of the population vaccinated against MMR decreased from $91\%$ in $1998$ to $80\%$ in $2004$. This may have led to the increase in the number of measles cases from $2001$ to $2003$ and from $2005$ to $2008$.
- CThe number of measles cases decreased from $80$ in $2003$ to $76$ in $2005$.
- DThe MMR vaccine does not give protection against measles because there is an increase in the vaccination rate from $2004$ to $2008$ and the number of measles cases increased from $2005$ to $2008$.
