WHO's _________ assesses the quality, safety, and efficacy of Covid-19 vaccines and is a prerequisite for COVAX Facility vaccine supply.

Correct option is D

✅ (d) Emergency Use Listing (EUL)
Explanation:
The Emergency Use Listing (EUL) is a risk-based procedure established by the World Health Organization (WHO) to evaluate and approve vaccines, medicines, and diagnostics during public health emergencies like COVID-19.
The EUL process ensures that vaccines meet international standards of safety, efficacy, and manufacturing quality before being distributed through global initiatives like COVAX.
Key Features of WHO’s Emergency Use Listing (EUL):
1. Accelerates Access to Vaccines
· Allows countries to fast-track approval of vaccines for emergency use.
· Helps governments make informed decisions about vaccine deployment.
2. Ensures Quality, Safety, and Efficacy
· Evaluates clinical trial data and manufacturing practices.
· Ensures that vaccines meet WHO standards before approval.
3. Supports COVAX Initiative
· COVAX (COVID-19 Vaccine Global Access) only distributes vaccines that have received EUL approval.
· Ensures equitable vaccine access to low- and middle-income countries.
4. Speeds Up Global Response
· Helps public health authorities combat pandemics more efficiently.
· Reduces delays in vaccine supply chains.
Why Other Options Are Incorrect?
❌ (a) Life Saving Drugs
· WHO has a List of Essential Medicines, but "Life Saving Drugs" is not a specific WHO listing for vaccines.
❌ (b) Listing of Highly Efficient Vaccine
· This term does not exist in WHO’s regulatory framework.
· WHO approves vaccines based on safety, efficacy, and risk-benefit analysis, not just efficiency.
❌ (c) Emergent Utility List
· There is no such WHO-approved list for vaccines under this name.
· The correct term is Emergency Use Listing (EUL).
Examples of COVID-19 Vaccines Approved Under WHO's EUL:
· Pfizer-BioNTech (BNT162b2)
· Moderna (mRNA-1273)
· AstraZeneca/Oxford (Vaxzevria)
· Johnson & Johnson (Janssen)
· Sinopharm BBIBP-CorV
· Sinovac-CoronaVac
· Covaxin (Bharat Biotech)
· Novavax (NVX-CoV2373)
Conclusion:
WHO’s Emergency Use Listing (EUL) is a crucial step for approving COVID-19 vaccines for global distribution. It ensures that vaccines are safe and effective before being supplied through COVAX and other global health initiatives.
Thus, the correct answer is (d) Emergency Use Listing. ✅
