Compare New Pneumococcal Vaccines to Prevnar 13 and Pneumovax 23
You'll see two new pneumococcal vaccines for adults, Prevnar 20 and 15-valent Vaxneuvance.
The new products are conjugate vaccines...like Prevnar 13.
The act of conjugating...or linking...to a carrier protein spurs production of memory cells. This may lead to longer-lasting and better immunity than polysaccharide vaccines, such as Pneumovax 23.
