The number of measles cases recorded in the Swansea outbreak has passed 1,000, according to Public Health Wales.
An ITV News/Com Res poll has found 71% of people think parents are acting irresponsibly if they don't get the MMR jab for their children.
71% of people think parents who do not vaccinate their children with MMR vaccine are being irresponsible, a ITV News/Com Res poll suggests.
Public Health Wales is warning of its concerns that outbreaks of measles may start to be seen outside of the Swansea area as cases continue to be reported across Wales.
There have now been 1,074 cases of measles in the area affected by the outbreak – an increase of 13 in the last two days – and 1,237 across the whole of Wales.
Dr Marion Lyons, Director of Health Protection for Public Health Wales, said: “Thirteen new cases in the last two days may not seem like a lot, but it should be remembered that in 2011, we only saw 19 measles cases in the whole of Wales for the whole of the year.
“There is no way of knowing where the next outbreak could strike so the message is simple – wherever you live in Wales, if you are a young person who hasn’t received two doses of MMR or the parent of a child who hasn’t, please arrange vaccination urgently".
The efforts to vaccinate susceptible children in the Abertawe Bro Morgannwg University Health Board area have been tremendous and we are delighted to see that around half of children needing vaccination have now received the MMR.
But with around 50,000 children in the 10 to 18 age group still not vaccinated, and more than 1,000 cases now reported to us, we cannot be complacent.

While not enough children are vaccinated, this outbreak can easily spread anywhere in Wales.
Therefore we urge parents of children, and young people themselves, to take up opportunities to receive the MMR vaccine as a matter of urgency.
The number of measles cases recorded in the Swansea outbreak - which started last November - has passed 1,000, Public Health Wales said.
Some 1,011 cases have now been recorded and 9,000 people aged between 10 and 18 still need to be vaccinated.
In the last month, 4,000 people have received the MMR jab.
But Public Health Wales has warned that the country as a whole needs to replicate Swansea's response to the outbreak, with 50,000 10 to 18 year-olds still unvaccinated across Wales.

Mr Cameron also said that British enterprise needs to up its game in the face of "great global race" that is under way.
"Our country will either be a success story or an also-ran.
"Let's remember who and what we're fighting for. For all those people who dream of a better future and who are prepared to work for it."
