Does a Cancer Vaccine Exist in India?

Cancer vaccines do exist in India, and they’re already in everyday use. The catch is what kind. The ones available now are preventive, they stop the infections that lead to certain cancers, rather than treating cancer that’s already there. The HPV vaccine and the Hepatitis B vaccine are the two big examples, both widely available.

According to Dr. Sandeep Nayak, Surgical Oncologist in India, “People hear cancer vaccine and picture a shot that cures cancer. That’s not what these are, at least not yet. The HPV and Hepatitis B vaccines prevent the viral infections that cause cervical and liver cancer. They work brilliantly, but only before exposure. The vaccines that treat existing cancer are still mostly in trials.”

India has preventive vaccines that genuinely stop certain cancers from ever starting.

• HPV vaccine : Prevents the high risk HPV strains behind most cervical cancer. Given to girls before exposure, it’s a true cancer preventer.
• CERVAVAC : India’s own HPV vaccine, made by the Serum Institute. Affordable and indigenous, it’s now part of a national rollout.
• Hepatitis B vaccine : Long part of routine immunisation. By preventing chronic Hepatitis B, it cuts the risk of liver cancer down the line.
• The catch : All of these are preventive. They work before the infection takes hold, which is why timing and age matter so much.

This is why prevention starts young, and proper cervical cancer treatment becomes far less likely in populations where HPV coverage is high.

This is where the science is moving fast, but the everyday reality lags behind.

• Therapeutic vaccines : These aim to train the immune system to attack an existing tumour. Different goal entirely from prevention.
• Still in trials : Most therapeutic cancer vaccines remain investigational worldwide. Promising results, but not yet routine care.
• Personalised approaches : Some newer vaccines are built around a patient’s own tumour mutations. Cutting edge, but far from widely available.
• The honest position : For now, treating cancer still rests on surgery, chemotherapy, radiation and immunotherapy. Vaccines treating cancer are coming, not here.

Prevention remains the proven path, which is why the HPV vaccine matters so much as a tool that stops cancer at the source.

Dr. Sandeep Nayak is a surgical oncologist with 24 years behind him and a fellowship in laparoscopic and robotic onco-surgery. He treats HPV related cancers, including cervical and head and neck disease, where prevention and early detection shape outcomes long before surgery enters the picture. The approach starts with separating what vaccines can actually do from the hype, since clear information is what lets families make sound decisions.

The distinction matters more than people realise. A preventive vaccine given at the right age can stop a cancer that would otherwise need major surgery years later. That’s a genuine win. Understanding which vaccines exist, what they do, and when they work is part of giving patients an honest, complete picture of their options.
