Beginning April 2018, BC and other Canadian provinces and territories will begin to use the pentavalent rotavirus vaccine (RV5, RotaTeq, Merck Canada) in their immunization programs for infants, replacing the use of the monovalent live attenuated vaccine (RV1, ROTARIX, GlaxoSmithKline), which has been used in BC since the program started in January 2012. This change is a result of a federally coordinated bulk-purchasing process in which all Canadian jurisdictions participate, and the term for the new contract will be for up to 3 years.
As is RV1, the RV5 is a live orally administered vaccine with similar contraindications. Both rotavirus vaccines are recommended for use by the National Advisory Committee on Immunization, without a preferential recommendation for one or the other. Both have been used globally in national immunization programs. Comparable vaccine effectiveness (VE) for the two has been observed in postmarketing surveillance evaluation for outcomes of hospitalization, emergency department visits, and outpatient visits. In low rotavirus mortality countries such as Canada, for RV1, median VE was 84% (range, 19%–97%) in 13 studies, and for RV5, median VE was 90% (range, 63%–100%) in 20 studies.[1]
The main difference for the BC program will be the schedule of immunization: for RotaTeq, is three doses, at 2, 4, and 6 months of age, whereas for ROTARIX, it was two doses at 2 and 4 months of age. The series can be started as early as 6 weeks of age, but Canadian recommendations are for series completion by 8 months and 0 days of age; these parameters are common to both products and are based on potential association with intussusception. Based on BC immunization registry data for participating health authorities (all but Vancouver Coastal), rotavirus vaccine 2-dose series completion rates have increased by 12% since the first year of the program. By year of birth, these rates are 70% for 2012, 75% for 2013, 79% for 2014, and 81.8% for 2016.[2] In moving to the RotaTeq product, however, providers will need to increase their efforts to achieve on-time immunization through use of reminders and recalls based on current completion rates for the coadministered DPT-containing vaccine. For infants born in 2016, while 87.6% received 2 doses of DPT-containing vaccine by 8 months of age, only 76.6% have completed 3 doses of DPT-containing vaccine by this milestone; 14.3% never started a series of rotavirus vaccine.
BC health units will be working with physician providers as they transition from RV1 to RV5, as the timing of this change will vary depending on remaining RV1 inventory at the local level. The two vaccines are not considered interchangeable and, ideally, infants who commence a series with RV1 should complete the second dose with that product. Those who must transition to RV5 after starting RV1 should receive a total of 3 doses of rotavirus vaccine.
In several prior surveys of BC parents, concern about vaccine safety has been the most frequently cited reason for refusal of vaccines. Both approved rotavirus vaccines have demonstrated high levels of safety and are well tolerated. While intussusception had been observed at a rate of about 1 in 10 000 recipients with a prior rotavirus vaccine approved in the USA in the 90s, this adverse event has not been consistently observed in all countries and studies using the RV1 and RV5 vaccines. At present and based on a large number of studies in different global settings, the generally accepted excess risk of intussusception is 1 to 2 cases per 100 000 vaccine recipients, mainly associated with the first dose.[3] This risk, however, has not been detectable in the Canadian population using administrative data on hospitalized intussusception among infants, and in that study there was no increase in the rate of intussusception following introduction of rotavirus vaccine.[4]
Finally, it is important for providers to be aware that administering the rotavirus vaccine prior to injectable vaccines given at the same visit has been demonstrated to provide comparable analgesic effect to that of orally administered sucrose solutions.[5] Both rotavirus vaccines contain similar quantities of sucrose[6,7] and this analgesic effect is expected with use of RV5 given prior to injectable vaccines, of which up to three injections are recommended for coadministration at the 2, 4, and 6 month visits, respectively.
