On 3 June, it was announced that the Center has booked 30 crore doses of a COVID-19 vaccine being manufactured by Hyderabad-based pharmaceutical company, Biological E.

The announcement comes on the heels of the Supreme Court slamming the Centre's vaccine policy and management in India.

With the deal sealed, Biological E’s COVID-19 vaccine is set to become India’s second homegrown vaccine to be rolled out.

However, it must be noted that the vaccine has not yet received emergency use authorisation from health authorities.

What do we know about this vaccine? FIT answers your FAQs.

Who is producing the Biological-E Vaccine?

The COVID vaccine is being produced by the oldest private vaccine company in India, Hyderabad based pharmaceutical company, Biological E. The name of the vaccine is yet unknown.

The vaccine was recommended for approval by the National Expert Group on Vaccine Administration for COVID-19 (NEGVAC), after it was cleared for Phase 3 clinical trials by the Drugs Control General of India (DGCI).

How does it work?

Biological E's COVID vaccine is a protein subunit vaccine.

To put it simply, a subunit vaccine uses only specific components of the pathogen, like particular antigens that best stimulate the desired immune response.

This is a widely used vaccine technology and is known for being very safe.

According to the WHO, owing to its safety, most vaccines in the childhood schedule, including tetanus, whooping cough, meningococcal meningitis are of this type.

Subunit vaccines often require adjuvants that help enhance the body's responses to an antigen, to trigger a strong immune response.

This particular vaccine uses the virus's protein antigen, SARS-CoV-2 Spike RBD, adsorbed to the adjuvant Al hydrogel (Alum), in combination with another approved adjuvant, CpG 1018 to trigger your immune system into action.

On 1 June, the company announced that it has partnered with a Canadian company, Providence Therapeutics Holdings, which will provide the technology needed to manufacture mRNA vaccines in India, with a minimum production capacity of 600 million doses in 2022 and a target capacity of 1 billion doses.
