India Rejects Chinese Polio Strain in 6-in-1 Vaccine

India's drug regulator, CDSCO, has said no to testing a new 6-in-1 vaccine for babies.

This vaccine was made by Indian Immunologicals Ltd and included a polio strain from China.

The regulator is worried that this strain could accidentally escape and bring back polio, a disease India has been free of for 14 years.

They also said the vaccine maker didn't provide enough safety data from other countries where it was used.

The vaccine company says the Chinese strain is safe and used in other countries, but the regulator wants more proof.

Health experts agree that keeping polio away is very important, and they don't want to take any risks.

Right now, India uses a 5-in-1 vaccine and separate polio drops, and the regulator wants to keep it that way until they are sure the new vaccine is safe.
