Dependence on antibiotics that are not effective against drug resistant bacteria can be reduced. 3. These vaccines have no side effects and cause no allergic reactions. Select the correct answer using the code given below:

1. Correct. Pneumococcal Conjugate Vaccine (PCV) protects against Streptococcus pneumoniae, which can cause pneumonia, meningitis and sepsis.
