Birth by C-section more than doubles odds of measles vaccine failure. Researchers say it is vital that children born by caesarean section receive two doses of the measles vaccine for robust protection against the disease.
A study by the University of Cambridge, UK, and Fudan University, China, has found that a single dose of the measles jab is up to 2.6 times more likely to be completely ineffective in children born by C-section, compared to those born naturally.
"We've discovered that the way we're born -- either by C-section or natural birth -- has long-term consequences on our immunity to diseases as we grow up," said Professor Henrik Salje in the University of Cambridge?'s Department of Genetics, joint senior author of the report. An increasing number of women around the world are choosing to give birth by caesarean section: in the UK a third of all births are by C-section, in Brazil and Turkey over half of all children are born this way.
They found that 12% of children born via caesarean section had no immune response to their first measles vaccination, as compared to 5% of children born by vaginal delivery. This means that many of the children born by C-section did still mount an immune response following their first vaccination. Measles is one of the world's most contagious diseases, spread by coughs and sneezes. It starts with cold-like symptoms and a rash, and can lead to serious complications including blindness, seizures, and death.
