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

Six HRV post-licensure controlled effectiveness studies
• 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.
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
