Key clinical features • Rotarix has demonstrated efficacy against several fully heterotypic strains,

providing evidence of broad protection against rotavirus currently

circulating. 1

• Rotarix has demonstrated sustained high levels of protection for 3 years,

with evidence of minimal waning immunity.2

• There is increasing evidence that widespread vaccination with Rotarix can

result in herd protection, thereby enhancing the benefits of vaccination

beyond the expected population based on trial data alone.3

• Rotarix vaccination has a substantial impact on all cause gastroenteritis,

reducing hospitalisation for gastroenteritis by 72% over a 2-year period in

a European study. This highlights the significance of rotavirus as a

causative agent.4

• Rates of nosocomial rotavirus infection have substantially decreased by

~67% and ~87% in Austria and urban Australia respectively after rotavirus

universal mass vaccination.5,6

• Significant protection against rotavirus-associated hospitalization was observed

in four of these studies ranging from 76 to 85% 11.

• The effectiveness study in Belgium has shown that two doses of Rotarix offer

vaccine effectiveness (overall), 91% (75% to 97%) 12

• RV vaccination reimbursed in Belgium since November 2006

• Using 1 September 2006 as the birth date to categorise

children with or without opportunity to receive RV vaccination,

data show a decline in the number of RV-positive samples

across successive birth cohorts

The estimates for Vaccine Efficacy seem to be different in various regions of the world; probably due to the high level of exposure early during the first months in developing countries

Early protection in UMV is important to help reduce the number of infections

Htay Htay Han, PV Suryakiran, Serge Debrus, Bernd Benninghoff WSPID - November 18-22, 2009, Buenos Aires, Argentina.

Rotarix 2 dose schedule can complete the

course as early as possible

• To be optimally effective and cost-effective, a

vaccination schedule should aim to induce

immunity with the fewest number of doses

before a sizeable proportion of the target

population acquires natural infection. In

countries, where natural infection occurs

early, completion of the immunization

schedule early in infancy is desirable.

Page 11: Welcome and introduction - Sabin

Conclusions

• Pre-licensure trials with HRV showed high efficacy rates against

clinically significant RVGE

• Post-licensure: HRV has had significant impact in reducing

severe RVGE, reduced the number of deaths due to RVGE and

demonstrate cost savings linked to the routine implementation of

rotavirus vaccination

• Rotarix is cost effective and reduces hospitalisations/mortality

and resource utilisation; in some countries Rotarix is cost-saving

from a societal perspective

• Real life data continues to confirm that Rotarix results in good

compliance and earlier completion with a two does schedule

• The main challenge is to increase RV vaccine use in National

Vaccine Programs, especially in less developed countries –

where early protection should be most impactful
