The anticipated roll-out of the CERVAVAC vaccine in India strikes a significant chord in national and global health circles. The vaccine, developed domestically, is aimed at preventing cervical cancer among girls aged 9-14 years. Schools are expected to play a key role in its distribution, with plans set to be implemented by mid-2023.
About CERVAVAC
Representing a stride in indigenous medical developments, CERVAVAC is India’s first locally produced quadrivalent human papillomavirus (qHPV) vaccine. Its formulation allows it to combat four strains of the HPV virus – Types 6, 11, 16, and 18. This particular type of vaccine functions by stimulating an immune response against these different antigens, like viruses or other microorganisms. Similar to the Hepatitis B vaccination, CERVAVAC relies on VLP (Virus-Like Particles).
Approval and Significance
The Drugs Controller General of India has granted approval for the vaccine, and a governmental advisory panel, NTAGI, has also endorsed its use in public health programs. The vaccine’s ability to potentially eliminate cervical cancer is seen as greatly advantageous, especially if incorporated into national HPV vaccination efforts. Moreover, it could be offered at a lower cost than existing vaccines, increasing its accessibility. Notably, the efficiency of the vaccine is highest if administered before the first sexual intercourse.
Cervical Cancer: An Overview
Cervical cancer, which develops in a woman’s cervix, ranks as the fourth most prevalent type of cancer among women worldwide and the second most common in India. According to a study published in The Lancet, India suffers the largest share of the global cervical cancer burden, accounting for nearly one in every four deaths due to this disease.
Nearly all cases of cervical cancer (99%) can be associated with an infection from high-risk HPV, a virus commonly transmitted through sexual contact. Primary preventive measures such as HPV vaccination and secondary prevention strategies like screening for and treating precancerous lesions, can significantly reduce the prevalence of cervical cancer.
A point to note is that cervical cancer, when diagnosed, is one of the most successfully treatable forms of cancer, provided it is detected early and managed effectively. Cancers diagnosed in late stages can be controlled using appropriate treatment and palliative care. A comprehensive approach involving prevention, screening, and treatment has the potential to eradicate cervical cancer as a public health problem within a generation.

The roll-out of the CERVAVAC vaccine aligns with the Government of India’s broader initiatives in healthcare, such as the ‘Mission Indradhanush’ launched on December 25, 2014. This immunization scheme aims to protect children and pregnant women against seven vaccine-preventable diseases, including diphtheria, whooping cough, tetanus, polio, tuberculosis, measles, and hepatitis B, by 2020. Supported technically by WHO, UNICEF, Rotary International, and other donor partners, it represents a critical step in expanding access to vaccines and ultimately improving health outcomes.
