COVID-19 Clinical Trials: Vaccines, Tests and Other Conditions


In our Weblog For Clinical Trials Day 2020, we summarized the COVID-19 research that had been recorded to date at ISRCTN Registry. A yr later and there are actually extra 170 COVID-19 research recorded. Within the first half from this weblog, we seemed on the outcomes of Platform checks and a collection of drug remedy reused checks launched since. On this weblog, we evaluation the outcomes of vaccine trials mentioned in our first weblog and research specializing in testing and the influence of COVID-19 on different situations.


A number of vaccines have been developed for COVID-19 around the globe. The vaccine developed by the College of Oxford and AstraZeneca has been examined in Phase I / II, Phase II / III and Phase III research and results confirmed that the vaccine was efficient.

The AstraZeneca vaccine has been accepted to be used in lots of nations, together with the UK. Mass vaccination towards COVID-19 started within the UK in early December 2020 and will possible proceed till mid-2021. The AstraZeneca vaccine is at present being examined in a Phase II examine in kids.

Other candidate vaccines are being examined within the COVAC1, CROWNED and SET 2 testing. There are additionally vaccines in growth from Valneva and the University of Queensland. The security of all vaccines is monitored by the VAC4COVID examine initially launched in the UK and by the ZVAC examine in Switzerland.

the VOC-COMPARE examine compares the immunogenicity of two doses of the AstraZeneca and Valneva vaccines, whereas the Com-VOC and Com-COV2 research examine completely different vaccine combos (eg AstraZeneca and Pfizer-BioNTech vaccines) for priming and booster doses, in addition to 4 and 12 week intervals between doses.

The length of safety for present vaccines is unknown and extra booster doses could also be required in 9 to 12 months, which can coincide with the seasonal influenza vaccination. Administering COVID-19 and influenza vaccines at separate appointments will result in vital logistical challenges, so the ComFluCOV The trial determines the security and immune response when the 2 vaccines are given to completely different arms on the similar appointment.

The checks have been proven to be important in containing the unfold of the virus. the results of CoV-19POC A examine has proven {that a} new point-of-care check for COVID-19 gives sooner outcomes and might enhance an infection management measures and affected person movement in comparison with centralized laboratory PCR testing.

In England and Wales, an infection charges in nursing properties have reached as much as 80% and loss of life charges as much as 30-50%. the VIVALDI is performing repeated testing (antigen and antibody) with workers and residents of well being amenities CONTACT A feasibility examine investigates whether or not transportable digital gadgets will help enhance contact tracing in nursing properties.

Now colleges have reopened within the UK containing the virus poses a specific problem on account of asymptomatic instances, excessive variety of contacts, presence of susceptible individuals and potential for transmission to household contacts of kids and workers.

Nonetheless, the authors additionally concluded that the excessive proportion of ladies from black or minority ethnic teams admitted with an infection required pressing investigation.

Research are additionally analyzing immune responses to COVID-19 and / or vaccination in sufferers with chronic health problems and immunocompromised sufferers reminiscent of these with Cancer and inflammatory bowel disease (IBD) handled with immunosuppressive or organic medication.

Final yr we additionally posted blogs on coronary heart illness and COVID-19, mind problems of COVID-19 and digital self-management for individuals residing with Most cancers throughout the pandemic.

Take residence message

the ISRCTN Registry continues to help international analysis on COVID-19 by prioritizing the well timed registration and notification of research associated to COVID-19. All recorded research are made obtainable worldwide by way of the International clinical trials registration platform (ICTRP), and all UK research seem on Be part of the research.
