Solution:Pneumococcal Conjugate Vaccine (PVC) is used to protect infants, young children, and adults against disease caused by the bacterium streptococcus pneumoniae.
These vaccines are at least 80 percent effective against meningitis, sepsis and bacteremic pneumonia. As per the Lancet Report (2017), these vaccines have reduced the burden of antibiotic-resistant bacterial disease globally. Hence, statement 1 and 2 are correct.
While statement 3 is incorrect as these vaccines may cause certain side effects (such as decreased appetite, fever, irritability, rash, reactions at the site of injection, fatigue, sleepiness, etc.) and allergic reactions (such as difficulty in breathing, hoarseness, fast heartbeat, dizziness, swelling of the throat,etc.).
