In Australia, she could have prevented more than 2,000 preterm births during the vaccination program.
A new study suggests that increasing vaccination coverage for human papillomavirus (HPV) can prevent thousands of preterm births around the world. Scientific work published in Infectious Diseases Journal,
It is known that women infected with HPV have an increased risk of premature birth. This is probably not a consequence of the infection itself, but the treatment of precancerous lesions of the cervix that it causes.
A study conducted by scientists from the New South Wales Cancer Council shows that the potential effects of mass vaccination against HPV may be associated not only with cervical cancer. In this work, it was found that in vaccinated women, the risk of premature birth is lower by 3.2%, and the probability of a low weight for their gestational age in children of vaccinated mothers was less by 9.8%. The latter means that babies are less likely to be born with a weight that does not match the number of weeks they spent in the womb.
The national HPV vaccination program was launched in Australia in 2007 and was one of the first in the world. If the findings of the new study are correct, then during its existence it prevented more than 2,000 preterm births in the country.
“These data show that the vaccine, along with the prevention of cervical cancer and other cancers associated with HPV, can play an important role in reducing the number of adverse pregnancy outcomes and improving the quality of life of many women and children around the world,” said Karen Canfell (Karen Canfell), director of research, New South Wales Cancer Council.
