Vaccination against measles should be mandatory for children before they start school in order to prevent future outbreaks of the resurgent disease, according to a new analysis released Friday, May 17.

The World Health Organization says cases of measles, a highly contagious viral infection that causes rashes and fever that can prove fatal, surged to 300% in 2018.

While many new cases occurred in countries undergoing unrest or conflict, several developed nations registered significant rises in infections, which phenomenon experts attribute to creeping “vaccine resistance.”

FEATURED STORIES

Despite a widely effective, almost universally available vaccine costing pennies, more parents are willingly putting their children in harm’s way due in part to a fraudulent scientific paper published over 20 years ago that subsequently fed conspiracy theories about plots to spread the disease.

Filippo Trentini and colleagues from the Bruno Kessler Foundation looked at seven rich nations and used computer modeling to examine several different vaccination scenarios between now and 2050.

They found that in nearly all countries surveyed, current immunization programs will be insufficient to maintain “safe” levels of immunity among populations.

The WHO said that the number of unvaccinated individuals in a given country should not exceed 6% to 8% of the population in order to avoid widespread outbreaks.

“This is a complex phenomenon and it may have various causes depending on the region,” Trentini told journalists.

“In high-income countries, for example, it may be attributable to vaccine resistance and to the clustering of unvaccinated people in specific groups of the population.”

Threshold breached

Under current vaccination programs, the study found that Great Britain, United States, Ireland, Australia and Italy would surpass safe levels of people susceptible to measles by 2050.

Indeed, the models showed that the proportion of unvaccinated people in Italy, home to several recent outbreaks, may already be over the 7.5% safety threshold.

In Great Britain, the unvaccinated rate of 3.7% was expected to rise to 8% by mid-century under the current national approach.

“It’s a very difficult task to forecast future epidemics,” Trentini said.

“The results suggest routine programs with current coverage levels are not enough to maintain the high immunity level required in the next decades.”

The authors of the BMC Medicine journal stressed, however, that mandatory vaccinations of school children, such as those implemented in France and Italy in recent years, would only be effective in conjunction with better public health awareness.

“There are some immunity gaps in Europe among adults,” said Piero Poletti, report co-author of the journal.

“These countries would certainly benefit from the introduction of vaccinations at school entry on top of current immunization programs.”

Sonia Saxena, professor of primary care at Imperial College London, welcomed the research but cautioned that mandatory vaccinations might have “unintended consequences.”

“It risks disenfranchising parents and carers, as well as risking a rise in unvaccinated children being excluded from school,” she said.

“The most important message for parents is that for (the measles vaccine), two doses by age 2 is the thing to remember. If everyone did this they would protect their child and also the whole community from outbreaks of measles,” Saxena added, who was not involved in the study. HM/JB
