Who created the vaccine for pneumococcal?
Pneumococcal typing systems developed by Franz Neufeld and others led to serotype-specific whole-cell vaccines. Pivotally, Alphonse Dochez and Oswald Avery isolated pneumococcal capsular polysaccharides in 1916-17.
What is the vaccine PCV7?
The Food and Drug Administration (FDA) licensed the first pneumococcal conjugate vaccine (PCV7 or Prevnar®) in 2000. That same year, the United States began using PCV7 routinely in children. It provided protection against infections caused by 7 types (serotypes) of pneumococcal bacteria.

Where is Prevnar manufactured?
“There is more that we can do to cut the costs of the vaccine, and that is to manufacture the vaccine here in Cape Town,” Pandor said at a news conference, as quoted by Reuters. The announcement was made at Biovac’s manufacturing facilities in Cape Town.
When was PPSV23 introduced?
The first pneumococcal vaccine, licensed in 1977, was a polysaccharide vaccine. It contained purified capsular polysaccharide antigen from 14 different types of pneumococcal bacteria. In 1983, a 23-valent polysaccharide was licensed (PPSV23; Pneumovax, Merck).
When was PCV7 discontinued?
7-valent pneumococcal conjugate vaccine (PCV7) was introduced into the routine pediatric immunization schedule in 2000 and was replaced by PCV13 in 2010 (4).
What is the best brand of pneumonia vaccine?
Pneumococcal conjugate vaccine (PCV13, Prevnar 13, Pfizer) is recommended for all adults without a prior PCV13 vaccination who have a high-risk condition, including immunocompromising conditions, cerebrospinal fluid (CSF) leak, and cochlear implant.
How is Prevnar made?
Prevnar was produced from the seven most prevalent strains of Streptococcus pneumoniae bacteria in the U.S. The bacterial capsule sugars, a characteristic of these pathogens, are linked to CRM197, a nontoxic recombinant variant of diphtheria toxin (Corynebacterium diphtheriae).
Which vaccines are conjugate?
The most commonly used conjugate vaccine is the Hib conjugate vaccine. Other pathogens that are combined in a conjugate vaccine to increase an immune response are Streptococcus pneumoniae and Neisseria meningitidis”, both of which are conjugated to protein carriers like those used in the Hib conjugate vaccine.
Who makes PPSV23?
Manufacturer: Merck Sharp & Dohme Corp.
