PREVENAR13 – Moving towards the Adult Franchise

Prevenar13 : US-FDA considers ‘protection of adults/elderly
from IPD and non-bacteremic pneumococcal pneumonia to
be a meaningful therapeutic benefit’over existing
treatments‘1
22 September 2011
Prevenar13: Active immunization for the prevention of IPD
caused by Streptococcus pneumoniae in adults aged 50
years and older.2
To date, over 50 nations have approved Prevenar 13 adult use - Thailand,
Australia, Bolivia, Philippines and a host of European countries among them3

*Notably, the number of childhood IPD caused by serotype 3 has increased from one
case in 2009 to six cases in 2010. Consequently, among children below 5 years of age,
the proportion of IPD caused by serotypes covered by PCV7*, PCV10* and PCV13 were
70%, 70% and 100% in 2009 changed to 47%, 47% and 93% respectively in 2010.1,2
Australia
OCTOBER 1, 2011
The Northern Territory has notified around 2 cases of invasive pneumococcal
disease caused by type 3, 6A and 19A per year in under 2 years old over the last 3
years.3

Prevenar13 - Countries shifting back2
Canada
November 17, 2010
Recently, both Ontario and Quebec announced they would publicly fund Prevenar13 as
part of the childhood immunization program, largely because it protects against additional
serotypes, notably 19A, not contained in either the 7-valent or the 10-valent vaccine.1

Summary

Most frequently reported AEs were pain/tenderness at injection site (9%)
and fever (6.7%)

AEs were not clinically significant and are in line with previous data1

Lesser in incidence compared with AEs reported in Prevenar PI



Other AEs noted (child lot fussier than usual, child lot sleepier than usual,
child eating much more poorly than usual and injection site reactions)
were transient, had < 2% incidence
Incidence of redness, swelling and a lump or hardness was much higher
with concomitant vaccines compared to PREVENAR
The incidence of pain and tenderness at the injection site was higher in
