− | To assess the sensitivity of the IPD predictions produced by the epidemiological model (assuming complete replacement)
| |
− | effects of 24 alternative scenarios regarding the role of certain serotypes in PCV10 and PCV13 were calculated, separately for <5 and 5+ year olds.
| |
− | | |
− | The results, shown in the table below, can be summarized as follows:
| |
− | | |
− | '''For <5 year olds'''
| |
− | * Inclusion of direct effects for 19A in PCV10 decreses the advantage of PCV13 from the default level of approximately 30 cases by 15.
| |
− | * Exclusion of 3 from PCV13 decreses the PCV13 advantage by approximately 2 cases. Inclusion of 6A in PCV10 decreses the PCV13 advantage by 4 cases.
| |
− | | |
− | '''For 5+ year olds'''
| |
− | * Exclusion of serotype 3 from PCV13 will decrease its advantage by 130 cases, practically eliminating the advantage.
| |
− | * Inclusion of 6A in pcv10 will inrease the PCV13-advantage by 30 (as 6A is not a good vaccine type for adults) and assuming that 6C carriage proportion (of 6AC) is 50% (instead of the default level of 33%) will increase it by 10.
