The Ministry of Health says the measles outbreak isn't at the point where they'd routinely immunise babies under 12 months. 

We have 13 infections - and 2000 close contacts.

Parents have worried vaccinating babies early can cost more than $200. 

The Ministry's Public Health Director, Dr Corina Grey, says allowing vaccinations earlier is a decision for health officials.

"We'll continue to track the outbreak and review the evidence - but encouraging everybody who is eligible to get vaccinated."
