COVID-19 Vaccine

COVID-19 Vaccine

There is currently no commercially available vaccine against the virus SARS-CoV-2. 

Research to develop a safe and effective vaccine is underway, with over one hundred currently under development globally. Some experts caution that there are no guarantees that a vaccine will become available - so far there has not been a successful vaccine against any of the coronaviruses which infect people (no vaccines against MERS-CoV, SARS-CoV, or the coronaviruses that cause the common cold). If any of the current vaccines in development do prove to be successful, it is estimated that they are unlikely to be be available for use until at least 2021.

The World Health Organization (WHO) have issued a Draft landscape of COVID-19 candidate vaccines. There are currently at least:

  • 10 candidate vaccines in clinical evaluation (human testing) - some have entered "phase 2b/3" of the testing process.
  • 121 vaccines in preclinical evaluation

For more information about some of the vaccine trials underway, see the News on Vaccines on this page.

For information about the Phases of Clinical Trials see the American Cancer Society What Are the Phases of Clinical Trials?

WHO is facilitating global collaboration for vaccine development.
Public statement for collaboration on COVID-19 vaccine development 13 April 2020

"As part of WHO’s response to the outbreak, a Research and Development (R&D) Blueprint has been activated to accelerate the development of diagnostics, vaccines and therapeutics for this novel coronavirus.

Under WHO’s coordination, a group of experts with diverse backgrounds is working towards the development of vaccines against COVID-19.

The group makes a call to everyone to follow recommendations to prevent the transmission of the COVID-19 virus and protect the health of individuals. The group also thanks everyone for putting their trust in the scientific community."
