A MMR vaccination rollout has led to a fall in the number of monthly measles cases.
Numbers from Public Health England show there were 113 cases in June compared with 193 in May and 299 in April.
The nationwide vaccination programme means almost 70,000 children aged 10 to 16 who previously never had the MMR jab as toddlers have now been completely vaccinated.
Despite this, warnings have been issued that hundreds of thousands more are still at risk.
Fifteen years ago, authorities saw a sharp decline in the uptake of the vaccinations after a study suggested there was a link between the combined measles, mumps and rubella (MMR) vaccine and autism
The study, led by Dr Andrew Wakefield, has since been discredited by scientists around the world.
Today, 60,000 previously unvaccinated children have now had one dose of the vaccine, according to the data from 2,000 English general practices, while 67,000 have had two doses.
Officials hope to vaccinate around 300,000 youths in the 10-16 age bracket with two doses, while targeting another 300,000 who are unvaccinated or partially vaccinated.
