Controversy over a research paper on Covaxin’s side effects

Source: The post controversy over a research paper on Covaxin’s side effects has been created, based on the article “A study on side-effects of Covaxin and three lessons in public trust and research” published in “Indian Express” on 15th October is 2024

UPSC Syllabus Topic: GS Paper 2– Governance-Issues relating to development and management of Social Sector/Services relating to Health,

Context: The article discusses a controversy over a research paper on Covaxin’s side effects. The study’s flawed methodology and unsupported conclusions led to criticism from the ICMR and legal action by Bharat Biotech. It highlights concerns about research independence and editorial responsibility.

What is the controversy about the BHU research paper?

1. The BHU research paper analyzed Covaxin’s long-term safety, published in Drug Safety in May 2024.
2. Small Sample Size: The study had a highly localized sample of 926 participants, which is statistically insignificant compared to millions vaccinated across India.
3. Misinterpretation of Data: The study’s claim that one-third of participants developed AESIs (adverse events of special interest) could lead to public misinterpretation, as this high percentage suggests significant risk without robust evidence to support such a claim. Although the paper didn’t claim a direct causal link, its language implied one, raising public concerns.
4. ICMR criticized the study for flawed methodology and improper use of AESIs.
5. Bharat Biotech filed a lawsuit against the authors, claiming it caused alarm and vaccine hesitancy.

What are the concerns about ICMR’s involvement?

1. Conflict of Interest: ICMR co-owns Covaxin’s patent with Bharat Biotech, raising concerns about impartiality when criticizing the BHU study.
2. Vaccine Development Role: ICMR’s National Institute of Virology provided virus strains for Covaxin, linking it closely to the vaccine’s success. Questions about ICMR’s impartiality were raised given its financial stakes in Covaxin’s success.
3. 2021 Concerns Resurfaced: Earlier questions about ICMR’s involvement in Covaxin’s development were raised in 2021 but subsided after the vaccine’s success. The BHU paper’s controversy has reignited these concerns.
4. ICMR’s Influence: Its criticism of the BHU study could be seen as protecting Covaxin’s reputation rather than encouraging independent research.

What are the Broader Implications?

1. Threat to Independent Research: If defamation cases against academics become common, as seen with Bharat Biotech’s lawsuit, it will discourage research, especially on drugs and vaccines. This could hurt consumers, who depend on unbiased scientific studies for safety information.
2. Need for Institutional Screening: ICMR and universities must see that medical research proposals are screened institutionally to avoid causing public mistrust or impacting the delivery of essential public health services, including vaccination.
3. Practical Research Methodology: Researchers should avoid drawing impractical conclusions. Staying grounded is crucial to producing credible, actionable research in medical fields.
