A number of potential coronavirus vaccines are entering the final stages of clinical trials.
US company Moderna has revealed that its COVID-19 vaccine is more than 94 percent effective.
Elsewhere, Pfizer and BioNTech’s vaccine was last week revealed to be at least 90 percent effective.
But, the end of the global pandemic will almost certainly spark a rise in childhood measles cases, experts have warned.
“The COVID-19 pandemic has had a profound effect on global immunisation and control of vaccine-preventable diseases,” the researchers wrote in The Lancet.
“Surveillance data from the first 6 months of 2020 suggest that measles case numbers are down in most countries, but this decline is ominous rather than reassuring, portending future outbreaks.
“The coming months are likely to see increasing numbers of unimmunised children who are susceptible to measles, many living in poor, remote communities where health systems are less resilient, and malnutrition and vitamin A deficiency are increasing.
“All these factors are likely to increase measles case fatality ratios, creating the environment for measles to return in 2021, accompanied by increased mortality and the serious consequences of measles that were common decades ago.”
Measles is a highly infectious viral illness – just like the coronavirus.
The infection can be very unpleasant, and it many even lead to life-threatening complications, warned the NHS.
The most common symptoms of measles include having small, greyish-white spots on the inside of the cheeks, as well as a high fever, and cold-like symptoms.
Some patients may even have sore, red eyes that are unusually sensitive to light.
