Can we administer PCV15 and PPSV23 vaccines to a person 65 years of age or older at the same visit? All adults for whom pneumococcal vaccination is recommended due to age 65 or older or an underlying condition age 19 through 64 are now recommended to receive a conjugate vaccine, even if they were only recommended to receive a single dose of PPSV23 alone in the past.
At least 90 types of pneumococcal bacteria are known to exist.
