... to a run rate … 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. 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. Influenza virus vaccine live intranasal--MedImmune vaccines: CAIV-T, influenza vaccine live intranasal. Anticipated success rates and timelines for COVID-19 vaccine development vary. How long will a vaccine really take? Vaccine trajectories for Dengvaxia and Ervebo. Trial characteristics were double-coded. 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.  |  2003;17(1):69-72. doi: 10.2165/00063030-200317010-00007. While vaccine effectiveness (VE) can vary, recent studies show that flu vaccination reduces the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well-matched to the flu vaccine.

Risk in vaccine research and development quantified. If the latest primary completion date was marked as “anticipated” on ClinicalTrials.gov or the trial status was not marked as “completed,” “active, not recruiting,” or “terminated,” the confirmed trajectory duration is indicated by a solid bar, and the interval between the latest confirmed date and the latest possible date is indicated by a segmented bar. FluMist. That means, for the current coronavirus pandemic, there is an excellent chance that a vaccine will win regulatory approval. This vaccine requires two injections given 28 days apart.
