1. These vaccines are effective against pneumonia as well as meningitis and sepsis.
2. 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:
Explanation
Statement 1 is correct: PCVs protect against infections caused by Streptococcus pneumoniae, which can lead to pneumonia, meningitis, and sepsis. This is particularly important in India, where pneumococcal diseases contribute significantly to child mortality.
Statement 2 is correct: By preventing pneumococcal infections, PCVs decrease the need for antibiotics, thereby mitigating the risk of developing and spreading antibiotic-resistant bacteria.
Statement 3 is incorrect: Like other vaccines, PCVs can have mild side effects such as fever, redness at the injection site, and, in rare cases, allergic reactions. No vaccine is completely free of side effects.
See, S2 uses "CAN be reduced", hence possibility logic likely true, but S3 uses absolute term "NO SIDE effect". is it possible a vaccine cause no side effect? unlikely hence S3 false.
