In China the babies do not receive protective antibodies against measles from mothers

According to researchers from the University of Michigan, in China, the mother did not pass protective antibodies against measles to their babies, which increases the risk of the disease before the age of 8 months. Furthermore, the level of protective antibodies decreases with age almost all infants who have no maternal antibodies.

Matthew Boulton from the School of Public Health at the University of Michigan said that the existing vaccination programs are ineffective for controlling measles transmission among infants. The researchers suggest that infants and their mothers need more protection.

"Effective treatment of measles in China requires a high level of vaccination among children and adopt new strategies that include immunization of people susceptible to the disease," - says Bolton.

The study involved 551 children between 1 and 8 months and their mothers. The results showed that when pregnancy goes full term, and her mother, perebolevaya measles receives proper nutrition, it transmits protective antibodies to the fetus. Mother who recover from measles are transmitted to the 1.6 times more antibodies than those who have not had measles or have not received the vaccine.

Measles remains one of the most highly infectious diseases in the world. Although the mortality rate has decreased by 79 percent since 2000, in 2015 she became the cause of death of 134,000 people worldwide, mostly in infants and young children. In China, the first dose of the vaccine administered in 8 months, and the second - after 18-24 months.

"Despite the high vaccination rates in the country, measles remains high among both infants and adults. This points to the need for new approaches, including the possibility of organized campaigns to immunize young women of reproductive age, many of whom have either never been vaccinated or received only one of the two recommended doses of vaccine against measles ", - explained the researchers.

According to Bolton, in both cases there is a problem. Additional and earlier dose for infants with an immature immune system can be inefficient and lead to increased costs. Additional vaccine for young women of reproductive age will increase costs, but it will increase the likelihood that the mother will give the required protective level of antibodies future children .
