Which vaccines are eligible for WHO prequalification?

Vaccines that fulfil four preconditions are eligible for prequalification:

1. the candidate vaccine is on the current priority list
2. the candidate vaccine meets the mandatory characteristics for programmatic suitability
3. a marketing authorization has been granted by the relevant national regulatory authority (NRA) and the post-marketing regulatory oversight is under the responsibility of the NRA of record
4. the NRA responsible for regulatory oversight in the vaccine's country of manufacture is confirmed by the WHO Global Benchmarking Tool to have the required "maturity level".
