See this image and copyright information in PMC. HHS ClinicalTrials.gov was searched to identify trials testing viral vaccines that had not advanced to phase 2 before 2005, and the progress of each vaccine from phase 1 through to U.S. Food and Drug Administration (FDA) licensure was tracked. Expert forecasts of COVID-19 vaccine development timelines [Letter]. However, despite the known success of vaccines in reducing morbidity and mortality, immunization rates remain relatively low across the U.S. in 2019, especially in the 19-35 month age range. One study found that between 2006 and 2015, the success rate of obtaining approval from Phase I to successful Phase III trials was 16.2% for vaccines, and CEPI indicates a potential success rate of only 10% for vaccine candidates in 2020 development.

Vaccines offer the most cost-effective solution to prevent both communicable and non-communicable disease in poor countries. Measurements: The authors review the timelines, and probabilities, of recent vaccines progressing from phase 2 clinical trials to licensure within 10 years. Following is what we know about China's vaccine development, efficacy data and approval timeline. Despite the need for speed, though, caution is needed. The probability of vaccines progressing from phase 2 to licensure within 10 years was 10.0% (95% CI, 2.6% to 16.9%), with most approvals representing H1N1 or H5N1 vaccines. [PMID: ] doi:10.1007/s11606-020-06244-9 Broadly speaking, orphan drug development has significantly lower success rates, with only 6.2% of drug development projects reaching the market. Data has shown that the vaccine has an efficacy rate of 94.1%. 30 April 2020. DNA vaccines see high Phase I failures as expected, and therapeutic vaccines have lower success rates than prophylactic vaccines. J Gen Intern Med. Lancet Glob Health.

Open diamonds indicate vaccine candidates that received FDA approval; X's indicate the Several vaccines are currently in large-scale studies to see if they can prevent COVID-19, and more are on the way. Primary funding source: Many issues have now been resolved, but co-operation between academia, regulators and industry remains a significant challenge, requiring links across new disciplines and technologies. Trial characteristics were double-coded. The History of Vaccines: “Vaccine Development, Testing, and Regulation.” Biostatistics : “Estimation of clinical trial success rates and related parameters.” Completed phase 1/2 and phase 2/3 trials are indicated by using both colors, with the first phase spanning a third of the total trial duration and the second phase spanning the remainder of the trial duration. Pharmaceutical manufacturer Johnson & Johnson announced Friday that early trials of a COVID-19 vaccine showed a 98 percent success rate in showing a boost in … Recent experience with developing and testing viral vaccine candidates can inform expectations regarding the development of safe and effective vaccines. Epub 2013 Mar 20. NIH Vaccine development is not an all-or-nothing endeavor. Results: A significant hurdle to achieving this, though, is that the fastest a vaccine has ever been developed, the mumps vaccine in 1967, took 4 years. latest confirmed primary completion date for a trajectory that coincides with a quelling in World Health Organization–reported outbreak activity. EVID = emerging and reemerged viral infectious disease. Epub 2018 Oct 18. ... to a run rate … Vaccine trajectories for EVIDs. CDC has been working with researchers at universities and hospitals since the 2003-2004 flu season to estimate how well flu vaccine works through observational studies using laboratory-confirmed flu as the outcome. Published studies suggest that vaccine research is seeing declining success. (Registration: Open Science Framework [https://osf.io/dmuzx/]). 2018 Dec;6(12):e1386-e1396. More than 56.7 million doses in 52 countries have been administered, according to data collected by Bloomberg. Each horizontal bar represents a single trajectory composed of 1 or more trials, beginning at the start date of the earliest trial of any phase since 2005 and ending at the primary completion date of the latest trial or the date of U.S. Food and Drug Administration (FDA) approval. Trials launched between January 2005 and March 2020. The typical success rate for vaccine development is 6%. Participants: The average timeline from phase 2 to approval was 4.4 years (range, 6.4 weeks to 13.9 years). 2020. But, the success story of vaccination is not yet finished. Success probabilities do not capture the varied reasons why vaccines fail to advance to regulatory approval. The primary end point was the probability of vaccines advancing from launch of phase 2 to FDA licensure within 10 years. This vaccine is for people age 18 and older. 2012 Aug 15;2012(8):CD007072.

Vaccines for infectious disease and ophthalmology drugs had the highest success rates, with 33.4% and 32.6% of Phase I compounds, respectively, eventually approved. Across all industry-sponsored vaccine development programs, we can see that monkeypox vaccines have had the most developmental success, followed by rotavirus and Japanese encephalitis vaccines (see Table 1).

FDA = U.S. Food and Drug Administration. Despite a historical average success rate of only 6%, and a usual gestation period of 10-12 years for the development of a new vaccine, the world is on the verge of developing COVID-19 vaccines in an extraordinary short time span. 28 years.
