RotaTeq® is an immunisation given to infants by mouth (orally) to protect them from severe rotavirus infection. RotaTeq® is free on the National Immunisation Schedule at 6 weeks, 3 months and 5 months of age - at the same visits as Infanrix®-hexa and either Synflorix® or Prevenar 13®.
The University of Otago is playing a major role in the international development of a new low-cost oral vaccine to protect newborn babies against rotavirus.
Rotvairus “gastro” is a life-threatening diarrheal disease that results in the death of over half a million children under five worldwide and two million hospitalisations each year. In New Zealand, rotavirus is responsible for 1500 hospital admissions of children under five years of age each year.
The research collaboration led by the Murdoch Children’s Research Institute at the Royal Children’s Hospital, Melbourne, is supported by the New Zealand Health Research Council and its Australian counterpart the National Health and Medical Research Council. The Dunedin Clinical Trial Team at the University of Otago began the second phase of the vaccine development in January this year.
University of Otago researcher, Dr Pam Jackson, from the Department of Women’s and Childrens’ Health, said that one dose of the rotavirus vaccine was well tolerated in the first phase of development in the Melbourne-based trial in babies, which was completed last year.
In the second phase of development of the vaccine, newborn babies and infants in Dunedin will be given three doses of the oral vaccine, called RV3-BB, or a placebo to ascertain the level of immunity to rotavirus generated by the vaccine. The vaccine is derived from a harmless strain of rotavirus found in newborn babies.
Children who have had this strain show no symptoms, and have shown to be protected against future infection by rotavirus strains.
Dr. Jackson said that unlike the current rotavirus vaccines that are available which are given to babies six to eight weeks of age, this vaccine will be given to newborns.
“This is important because we know that infection can occur very early in developing countries and means that the vaccine has the potential to save many thousands of lives by vaccinating at birth while babies are still in a health care setting,” she says.
“After this time, babies are often lost track of, when their risk of the severe rotavirus disease is very high. By starting vaccination from birth we will be potentially able to offer them protection from rotavirus disease by three months of age.”
At present in New Zealand and many other countries, the currently available rotavirus vaccines are not part of the National Immunisation Programme of funded vaccinations, mainly due to cost.
The research and development of this vaccine is being led and conducted by academic institutions rather than the pharmaceutical industry with the intention to partner with developing country manufacturers so that the vaccine will ultimately become available at lower cost for developing countries, where they are needed most.
Dr. Jackson says that there is significant potential benefit of a lower cost, effective vaccine for babies from birth in developing nations, and also to the healthcare system, children and their parents in developed nations such as New Zealand.
In the next few months, expectant parents will be given information about the trial and asked whether they wish to participate.
“This oral vaccine has been shown to be well tolerated. What we now need to know is how effective the vaccine is at protecting against the disease and how long protection lasts.”
As of 9 May 2013, GSK have advised that they are continuing to make Rotarix available to patients at a significantly reduced price through the Rotarix patient access programme to at least the end of 2013.
To improve the access to rotavirus vaccine for New Zealand children through a discount offer direct to all caregivers.
To reduce the impact of rotavirus on families – twelve children go to hospital every day in NZ due to rotavirus.
1. As of the 1st of February 2012, Rotarix will be publicised to parents & caregivers at a 38% discount of $100 for the two doses, plus GST and any required practice handling charges, enabling more children to be protected from rotavirus.
Healthcare Logistics will still charge a small order handling fee of $45 for orders of 1-4 vaccines, the Rotavirus twin pack will be counted as two vaccines.
2. Parents & caregivers will be directed to contact their general practice for further information on the rotavirus vaccine.
3. Ordering will be by the usual process of fax or online order form to Healthcare Logistics.
4. The programme will available throughout the remainder of 2012.

Rotarix® is used for primary vaccination of infants to protect from rotavirus infection. The first dose is given between six and 14 weeks of age.
In the late 1990s a different rotavirus vaccine was associated with intussusception and removed from the market. The new vaccine has been tested in over 70,000 children and no link with intussusception was found. As part of ongoing vaccine safety monitoring a large study of Rotarix® in Mexico suggested there may be a small increase in the risk of developing intussusception following the first vaccine dose.
The U.S. Centers for Disease Control and Prevention (CDC) reviewed all the information available. They recommended that as the increased risk of intussusception is extremely small and the benefits of rotavirus vaccination are great, Rotarix® continue to be used to prevent rotavirus disease.
No. The vaccine only protects against severe diarrhoea and vomiting (gastroenteritis) caused by rotavirus. The vaccine does not protect against gastroenteritis caused by other viruses or bacteria.
