However, weak evidence suggests that for patients aged 65-80 who have not received the PPV previously, a single-dose PPV strategy is both clinically and economically indicated. For patients 65 and above who have already received one dose of the PPV vaccine, the decision whether to revaccinate depends of vaccine tolerance and the cost-effectiveness/willingness-to-pay threshold used.en-USpneumococcal vaccinationpneumococcal revaccinationPPV23guidelineselderlyage 19-64age 65age 65+Other
