The Delta variant of the COVID19 virus has caused widespread infection in India with a notable increase of cases in the United Kingdom, the United States, and 93 other countries across the globe. The dominant variant is highly contagious in comparison to the Alpha variant. According to F. Perry Wilson, MD, a Yale Medicine epidemiologist, the Delta variant is sure to accelerate the pandemic. The spread of the Delta variant has a significant effect on patients with end-stage renal disease in clinical research trials.

Vaccination is becoming increasingly important for all populations, especially so for those at higher risk. Anyone who is immune-compromised, a senior or child, unvaccinated, and not practicing safety health standards is at higher risk.

What is the Delta Variant?

Delta is the newer strain of COVID19 causing widespread infection in 96 countries around the world.

The delta variant originated in India and has quickly infected millions of individuals. In the United States, the delta variant totals more than 80% of new cases.

Delta COVID19 variant is affecting unvaccinated people more. Most patients who have been hospitalized are those who have not received their COVID19 vaccine. Across the United States, almost all patients hospitalized due to COVID19 infection are not vaccinated. And based on data, states with lower vaccination rates have the highest COVID19 infection.

Why Does the Variant Affect Clinical Research?

The new Delta variant is wreaking havoc worldwide. Not only that, the surge of Delta COVID19 cases can affect current clinical research. The scientific community is still grasping SARS-COV-2 and the delta variant.

Even with the availability of COVID19 vaccines, clinical research is still ongoing. Researchers and scientists are still struggling to find the absolute treatment for COVID19. The vaccine can only do so much for patients who are severely ill.

While countries are still working on reaching herd immunity, researchers continuously gathered data about the delta variant for their clinical research. But so far there has been no ultimate treatment for COVID19 or the delta variant yet.

With the ongoing pandemic and virus mutation, researchers will continue to grasp the behavior of the virus. At the same time, the medical research and healthcare industry are bracing themselves for greater threats.

Is Vaccination Effective Against Delta Variant?

As shown by clinical research, clinical trials, and real-world evidence, COVI19 vaccines are highly effective in combating symptomatic disease. But with Delta dubbed as the fastest and the fittest, the virus can spread quickly which can infect more people than the Alpha strain.

A recent study in the United Kingdom reveals that younger and unvaccinated groups are very likely to get the Delta COVID19 variant. But those who receive their full doses have lower risks of serious disease, hospitalization,

The current and available COVID19 vaccines efficiently work to prevent the spread of the virus. Although the vaccine is effective towards the original variant, scientists are still working on establishing whether these vaccines are also effective towards the delta variant.

As per updates and analysis done by different labs show that receiving the full doses COVID19 vaccine provides a higher percentage of protection from severe disease and protection against hospitalization for the delta variant.

It is said that the Pfizer BioNTech COVID19 vaccine has 88% protection against severe disease and 96% for the delta variant.

On the other hand, the Moderna COVID19 vaccine provides 77% effectiveness from one dose against delta. As for Johnson and Johnson’s Janssen COVID19 vaccine, a study suggests that it is 67% effective against delta.

For now, receiving full administration of the COVID19 vaccine is the only way to slow down the spread of the SARS-COV-2 virus.
