There are no vaccines for COVID-19 yet.
However, many potential vaccines are being studied and several large clinical trials may report results later this year.
If a vaccine is proven safe and effective, it must be approved by national regulators, manufactured to exacting standards, and distributed.
when developed, how can it be distributed?
WHO is working with partners around the world to help coordinate key steps in this process.
Once a safe and effective vaccine is available, WHO will work to facilitate equitable access for the billions of people who will need it
