Reasons cited for decreased immunogenicity:
• Study cohort healthier.
• No concomitant administration of OPV.
• Age of 1st dose earlier (6 vs 8 wks)-Possible interference
by maternal anti RV IgG.
• Possible Breast feeding interference with “TAKE” of RV
vaccine (controlled in 1b/IIa).
• Variability in Anti RV IgA response in different populations

Vaccine is stable for1 (2017 paper)
• < 250C for 36 months.
• 18 months at 37◦C, and 40◦C,
• 55+/- 20C for 72 hrs.
• -200 C for 48 hrs & 42+/-20 C (Stable even
after 2 freeze thaw cycles)
Summary:
• Heat stable vaccine which can be stored
below 250C & does not need refrigeration.
• Was developed to reduce cold storage
space for RV vaccines supplied for NIPs2.
Reconstituted vaccine must be used
immediately. If not used
immediately, it can be held for a
period of maximum 6 hours
provided a syringe is used to cap the
opening of the vial adapter & the
entire assembly is stored at 2-80 C 2.
Important if Multi dose (5 ml) packs
are supplied.

individual G-serotypes included in the vaccine (G1, G2, G3, and G4);
• P1A[8] was included in the vaccine to potentially provide cross-protection against
nonvaccine G-serotypes that may contain P1A[8].

We are confident that

diarrhoea
We are confident that

* Downgraded due to indirectness as trials were conducted in Malawi and South Africa: generalization to high--‐mortality countries is difficult.

Editor's Notes
Now what Indian data we have.
Indian immunogenicity data of RV1 and RV5 and also 116E which is upcoming vaccine is available.
Only RV1 was evaluated in two doses and it had serocoversionof 58.3%
While RV5 and 116E (with its higher dose) had seroconversion of more than 80% and both these were used in three dose schedule.
Only RV5 was given right from 6 weeks and along with OPV. Others were started little late and there was no concomittant OPV.
So RV5 was tested under the all possible challenging conditions.
