If the virus becomes active again, shingles is the name given to the symptoms it causes and can't be caught by human contact.
The supplier of the vaccine, Merck Sharpe and Dohme, has advised that due to manufacturing constraints the next delivery of the vaccine has been delayed and won't be in New Zealand until early July.
"While there is currently some stock, we expect that there will be a short period where the vaccine isn't available in some parts of the country."
Pharmac has said that it was pleasing to know that so many New Zealanders had taken the opportunity to be vaccinated against the shingles infection.
