Bharat Biotech clarifies no calf serum in COVAXIN end product

Published

on

Responding to a Right To Information(RTI) reply that has stirred a controversy, the Hyderabad-based Bharat Biotech on June 16, Wednesday issued a statement saying that the final Covaxin dose administered to people does not have newborn calf serum. The controversy began a day earlier when an RTI filed by a person identified as Vikas Patni revealed that new calf serum has been used in the revival of Vero cells which is used for the production of Covaxin.

In a statement issued on June 16, Wednesday, Bharat Biotech said, “Newborn calf serum is used in the manufacturing of viral vaccines. It is used for the growth of cells, but neither used in the growth of the SARS CoV2 virus nor in the final formulation. Covaxin is highly purified to contain only the inactivated virus components by removing all other impurities.”

The company added that Bovine serum has been widely used in the manufacture of vaccines globally for several decades. “The usage of newborn calf serum was transparently documented in the following publications since the last 9 months,” the company added.

The Union Health Ministry on Wednesday also issued a clarification, stating that while the serum is used only for the manufacturing of vaccines, the final vaccine does not contain newborn calf serum at all. The Union Ministry of Health and Family Welfare added that facts have been “twisted and misrepresented” in social media posts regarding the composition of the vaccine and the suggestion that Covaxin contains newborn calf serum is not correct.

“Newborn Calf Serum is used only for preparation/ growth of Vero cells. Different kinds of bovine and other animal serum are standard enrichment ingredients used globally for Vero cell growth. Vero cells are used to establish cell lives which help in the production of vaccines. This technique has been used for decades in Polio, Rabies, and Influenza vaccines,” the Union government said in a release.

“These Vero cells, after the growth, are washed with water, with chemicals (also technically known as a buffer), many times to make it free from the newborn calf serum. Thereafter, these Vero cells are infected with coronavirus for viral growth,” the government added.

“Hence, the final vaccine (COVAXIN) does not contain newborn calf serum at all and the calf serum is not an ingredient of the final vaccine product,” the Union government said.

Environmentalists Criticize CIDCO for Calling DPS Flamingo Lake ‘Vacant Land’

Published

Activists seek urgent notification of Conservation Reserve status and stronger protection for Nerul wetland.

The Criticism

Environmentalists have criticised the City and Industrial Development Corporation (CIDCO) for describing DPS Flamingo Lake in Nerul as “vacant land” in a tender for a flamingo habitat study. They have urged the Maharashtra government to expedite the formal notification granting the ecologically sensitive wetland Conservation Reserve status. NatConnect Foundation has written to Chief Minister Devendra Fadnavis, alleging that CIDCO’s description undermines the state wildlife board’s decision to declare the lake a Conservation Reserve. NatConnect director B N Kumar said the government resolution formalizing the status had reportedly been pending for nearly a year, according to a Forest Department response to a Right to Information (RTI) query.

Environmentalists have also questioned the need for another study. Rekha Shankhala of the Save Flamingos and Mangroves Forum urged authorities to publish findings from previous studies and clarify the status of the proposed reserve. Sandeep Sareen of the Navi Mumbai Environment Protection Society alleged that CIDCO had disregarded High Court rulings recognising the site as a wetland. He also claimed that the blocking of intertidal water flow had harmed the lake’s ecological character.

CIDCO’s tender, dated October 27, 2026, seeks an expert to study the flamingo habitat near DPS, Nerul, close to Navi Mumbai International Airport. The proposed study will run for six months, and eligible consultants must have experience in bird-hazard assessments at airports. Environmental groups have highlighted recommendations by the Bombay Natural History Society to protect wetlands around the airport, including DPS Flamingo Lake, NRI Lake and TS Chanakya Lake. They have called for prompt government action to secure the wetland’s long-term protection.

The Demand

The Shiv Sena (Uddhav Balasaheb Thackeray) has demanded immediate road safety measures near Turbhe railway station and the adjoining Thane-Belapur highway, alleging that poor road engineering and administrative negligence have made the stretch dangerous for commuters and pedestrians.

A party delegation submitted a memorandum to the Navi Mumbai Municipal Corporation (NMMC) commissioner, city engineer and Turbhe police, seeking urgent action to prevent further accidents. According to the memorandum, more than 40 people have died and over 80 have suffered serious injuries in accidents in the area. The death of a woman pedestrian on October 26 has renewed concerns over road safety, the party said.

The delegation demanded scientifically designed speed breakers, rumble strips, high-mast streetlights, clearly marked zebra crossings and safety barricades on the highway stretch from Panvel towards Thane. It also sought accountability for officials allegedly responsible for safety lapses, compensation for accident victims and their families, and legal action against engineers found negligent. The party urged traffic police to deploy personnel round the clock at the junction opposite Turbhe station and other accident-prone locations. It also called for CCTV surveillance and strict action against speeding, signal violations and wrong-side driving.

Additionally, the delegation demanded the removal of illegal tempo stands and unauthorised parking, along with towing of illegally parked vehicles.

The delegation included divisional chief Pravin Patil, party worker Balkrishna Khaparde and branch chief Akash Itkar, among others. The party warned that if speed breakers and other safety measures were not implemented within seven days, it would stage a protest outside the NMMC headquarters under district chief Prakash Patil’s guidance.
