Boosting successful infectious disease & vaccine clinical trials

Successful infectious disease and vaccine clinical trials are a race against time, and competing studies. 

  • Outbreak windows can close before trials do, many will never complete 
  • 1 in 3 people worldwide have vaccine hesitancy, reducing your patient pool 
  • The global vaccine pipeline consists of over 900+ active candidates, all trying to find willing patients 

Through rapid campaign activation, epidemiology-driven patient targeting, scalable digital recruitment, and protocol-specific pre-screening, we help sponsors find, engage, and recruit the right participants, faster.

  • "It went very nicely they ask you the needed questions and you just click on the answer that suits you and your condition. I'm sure this will be a fine experience and we may get to a cure as well. If you are thinking about joining up with ClinLife® research studies I think you make a wise choice. I did and looking forward to the study.”

Infectious disease & vaccines FAQs

How many infectious disease & vaccine indications does Clariness support?

Clariness supports recruitment across a wide range of infectious disease & vaccination indications, including herpes zoster, herpes labialis (oral herpes), human papillomavirus infections, Clostridium difficile infection, onychomycosis (Athlete’s foot), hepatitis B&C, RSV, Influenza, COVID-19, and many others. 

Vaccine trials recruit healthy volunteers or prevention cohorts while competing with public vaccination programs and other clinical studies for the same participants. Public perception and vaccine hesitancy can also reduce engagement. Clariness overcomes these challenges through targeted community outreach and patient-centric educational campaigns that build trust and increase participation. 

Infectious disease trials often have narrow recruitment windows driven by disease outbreaks and local epidemiology. Clariness uses rapid campaign activation, scalable recruitment strategies, and geography-based targeting to quickly identify eligible participants.

Infectious diseases & vaccine clinical trials often compete with public vaccination programs and concurrent clinical trials for the same participants. Clariness continuously adapts recruitment campaigns based on disease trends, site performance, and epidemiological data to maintain enrollment momentum. 

COVID-19 clinical trials often require participants to be identified and referred within days of diagnosis, while protocols evolve throughout the study. Clariness streamlines recruitment through unified protocol-specific screening, rapid participant follow-up (within 1 hour of registration), and flexible recruitment strategies that adapt to changing study requirements.
