Delta Highly Contagious Despite Vaccines

Reuters advised on July 20, 2021 vaccinated people might need to reinstate masks, social distancing and other measures. This was after CDC confirmed vaccine breakthrough cases might be as contagious as unvaccinated ones. Now, Reuters confirms a Public Health England study agrees Delta is highly contagious despite vaccines, in breakthrough cases.

Vaccinated People May Be Able to Transmit Delta as Easily

The UK finding that vaccinated people may transmit the Delta virus readily, reflects the CDC concern we reference below. This may explain the current hospitalization uptick in United Kingdom, despite nearly 75% of residents having two vaccine doses.

A Public Health England statement advises, ‘Some initial findings … indicate levels of virus in those who become infected with Delta having already been vaccinated, may be similar to levels found in unvaccinated people. This may have implications for their infectiousness … but this is early exploratory analysis.’

‘As more of the population has vaccinations,’ Public Health England advises. ‘We will see a higher relative percentage of vaccinated people in hospital.’ This could be why 34.9% of Delta hospitalizations in UK since July 19 were vaccinated people.

Does This Mean the Vaccination is a Failure?

No not at all. The delta variant may be highly contagious despite vaccines in break-through cases, but those treatments are succeeding in their primary role. That primary goal is reducing the severity of infections and deaths. Contrast the following graphic with the one at the top of our article, and it’s evident this is happening in United Kingdom.

United Kingdom Daily Number of Confirmed Deaths (Our World in Data August 7, 2021)

The deaths have remained low throughout the United Kingdom’s third wave. This is proof the vaccines are working, and meeting their primary objective. However, we might need to reinstate masks, social distancing and other measures for a while. That’s until our scientists develop a permanent solution, which will require more time.

Electricity has always intrigued me. I have been writing about batteries and energy storage for more than ten years, and have published over 4,000 articles on this website. During that time, I have researched developments across lead-acid, lithium-ion, sodium-ion, flow batteries, and emerging energy-storage technologies. My goal is to explain complex battery concepts in clear, practical language that anyone can understand. My writing career began unexpectedly after leaving the corporate world. What started as a search for a new direction gradually became a fascination with batteries, renewable energy, and the science that powers modern life. Writing may not have made me wealthy, but it has given me the opportunity to explore an industry that continues to evolve in remarkable ways.
