Learn more about developing COVID-19 vaccines. authorized or approved COVID-19 vaccines using data from several monitoring systems. CDC and FDA continue to provide updated information on the safety of U.S. Hundreds of millions of people in the United States have safely received COVID-19 vaccines. Tracking Safety Using Vaccine Monitoring Systems – Like every other vaccine approved for use in the United States, COVID-19 vaccines continue to be monitored for safety and effectiveness.

FDA has determined COVID-19 vaccines meet FDA’s standards and has granted those vaccines Emergency Use Authorizations (EUAs) or full FDA approval. Food and Drug Administration (FDA) reviews data from clinical trials.

Authorization or Approval – Before vaccines are available to people, the U.S.

The phases overlapped to speed up the process, but all phases were completed.

Clinical Trials – All vaccines in the United States must go through three phases of clinical trials to ensure they are safe and effective.

All vaccine development steps were taken to ensure COVID-19 vaccine safety and effectiveness, including: ET every weekday for special coverage of the novel coronavirus with the full ABC News team, including the latest news, context and analysis.Although COVID-19 vaccines were developed quickly, research and development on vaccines like these have been underway for decades.

What to do if you have symptoms: Coronavirus symptoms.

How it started and how to protect yourself: Coronavirus explained.'In the middle of this fast approach, we absolutely cannot compromise on safety.' What to know about the coronavirus: 'Time is critical, of course, but safety is critical,' said Duprex. If something goes wrong … the general public will extrapolate that vaccines are unsafe.' 'Vaccines are so, so important for public health,' Duprex said. 'Most vaccines have been pretty safe, but there have been problems in the past,' said Goepfert.Īnd the downside of immunizing millions of people with a rushed, unsafe vaccine could have long-ranging consequences. Many of these vaccines use different technology - some brand-new to vaccine science - and experts still don't know which is the most likely to work.Īnd rushing development could mean that important safety issues are missed. The furthest along include candidates from the University of Oxford, Pfizer, Moderna Therapeutics, Inovio Pharmaceuticals and China's CanSino Biologics.

Right now there are more than 100 vaccines being studied, and at least eight of those have already progressed outside the laboratory and into human studies, according to the World Health Organization. 'It's very difficult to say something about a timeline.' 'Those are quite complicated discussions,' she said. There are several complicating factors that could easily delay the timeline beyond 18 months, including the fact that the studies will need to be conducted in places where the virus is still circulating. 'It's difficult to set exact timelines,' said Rinke Bos, principal scientist and immunologist for Johnson and Johnson - one of the companies advancing a COVID-19 vaccine.

'It is possible but not likely,' Goepfert said. But the prior record for vaccine development - the mumps vaccine - took four years, meaning Fauci's early estimates drew skepticism among many vaccine experts. epidemic, Fauci has been estimating a vaccine is 12 to 18 months away. Anthony Fauci, the nation's top infectious disease doctor, said, 'we want to go quickly, but we want to make sure it's safe and it's effective.' While President Donald Trump has been bullish in his promise to have a 'vaccine by the end of the year,' his top advisors have taken a more measured approach, saying a January deadline is a best-case scenario. With top White House officials indicating a coronavirus vaccine may be available by January 2021, scientists and vaccine experts outside the Trump administration are cautious but optimistic that a vaccine could be delivered on such an accelerated timeline.Įxperts interviewed by ABC warned that developing a vaccine within a 12-month time frame could mean throwing normal scientific standards out the window, but added that a vaccine could be available by the new year if everything goes perfectly.
