Low measles vaccination rates in the Bay of Plenty and Lakes should be a concern after six confirmed cases in the country, an immunology lecturer says.
Health New Zealand Te Whatu Ora is responding to an “escalating national measles outbreak” after cases were confirmed in Northland (one), Auckland (two), Manawatū(two) and Nelson (one), a statement from the agency on Thursday said.
These are in addition to the 10 cases reported earlier this month in Northland and the one case in the Queenstown-Lakes district, Health NZ said.
Measles is highly contagious and can cause serious and potentially long-term health problems, Health NZ said.
AUT immunology lecturer, biomedicine and medical diagnostics Dr Chris Puli’uvea told NZME there was a “decent chance” measles would reach the Bay of Plenty if someone from the Bay who was in or around the locations of interest of the confirmed cases had since returned home.
This chance would increase if this person was not fully immunised against measles, he said.
Puli’uvea said one infected person with Covid-19 could infect three to four people. For measles, one infected person could infect up to 18 other people.
The measles virus could remain airborne for up to two hours, “so people congregating in several places will be a perfect breeding ground for the virus”, he said.
The measles, mumps, and rubella (MMR) vaccination is part of Health NZ’s national immunisation schedule given to children before they turn 2.
The latest Health NZ data on its website showed 75.9% of 2-year-olds in the Bay of Plenty region had completed all of their age-appropriate immunisations for the three-month period ending June 30 this year.
In the Lakes region, it was 72.8%.
For Māori children in the Bay of Plenty, it was 63.3%, and in the Lakes, it was 64.6%.

“We should be concerned with this low level of vaccination rates,” Puli’uvea said.
He said a 95% fully vaccinated rate was needed to ensure those who could not get vaccinated (children under 12 months) and immunocompromised people were protected.
Puli’uvea said vaccination strategies used during the Covid-19 pandemic should be revisited to “boost” rates to reach 95%.
“Our communities know what works best for them, we should call on them again to drive these numbers up.
“We don’t want our children suffering from the long-term effects of a measles infection.”

Rotorua’s Korowai Aroha Health Centre chief executive Hariata Vercoe said it “strongly” advocated for parents of children who were not immunised to do so.
Appointments and walk-ins were available at the centre, which was open Monday to Friday from 8.30am to 5pm, she said.
On the Lakes immunisation data, Vercoe said a “rebuild” of trust was needed.
When the Covid-19 vaccination mandates were introduced, “people lost a lot of trust” in immunisations, she said.
“For us, it’s about being in contact ... and making sure there’s information available.”
Health NZ says more cases ‘likely’
Health NZ said four of the six cases were linked to a 2pm to 5.30pm Bluebridge Ferry sailing from Picton to Wellington on October 3, where an infectious measles case was on board.
National Public Health Service public health medicine specialist Dr Sharon Sime said it was “likely” there were more cases in the community yet to be reported.
Sime advised people to remain vigilant for measles symptoms, stay home if unwell and avoid travel and seek healthcare advice.
People considered close contacts were asked to quarantine to help contain any potential spread until their immunity status was confirmed. Once someone was confirmed immune, they could be released, she said.
Sime said the best protection was to ensure people were up to date with two doses of the MMR vaccine after 12 months of age.
The MMR vaccine was free in New Zealand for anyone aged under 18, and for people over 18 who are eligible for free healthcare.
Measles locations of interest were on the Health NZ website. People could also check their immunity status on the website or call the vaccination helpline on 0800 28 29 26.
Anyone suspecting they have measles was asked to phone ahead before visiting their doctor or health provider so they could take precautions to prevent measles spreading.
