This article on the BBC website caught my eye - Covid vaccines: Why a giant plastic bag shortage is slowing the rollout. This is a huge deal right now in the pharmaceutical industry

Old Boy's theory only works if vaccines don't help prevent transmission.

Funnily enough . . . they don't in this case

The word “Theory” is doing some heavy lifting here.

They reduce but don't completely stop it

A new study by Public Health England (PHE) has shown that one dose of the COVID-19 vaccine reduces household transmission by up to half.

You sure about that?

I'm pretty sure yes, otherwise anybody that's been 'double jabbed' would be free to go about their life without the risk of catching it again and spreading it to others . . . can they?

To my understanding, it's a percentage of people who have been fully vaccinated that are still able to catch and transmit, not all.

Based on reading & listening, pretty sure. Happy to be corrected should someone have the evidence to the contrary however.

Found this about the Pfizer vaccine, although not sure which variant this is for
https://www.news-medical.net/news/20...nsmission.aspx

These models estimated 80-88% vaccine effectiveness against susceptibility (VES), to COVID-19 infection, for the individuals who had received both doses of the vaccine. The vaccine's effectiveness against infectiousness (VEI) was found to be 41.3%. Additionally, the overall vaccine effectiveness against transmission (VET) was found to be 88.5%.

And I believe those stats are separate from the ability to reduce serious illness and death in the person vaccinated

A full course of the Pfizer-BioNTech vaccine was just 39% effective at preventing infections and 41% effective at preventing symptomatic infections caused by the Delta Covid-19 variant, according to Israel’s health ministry, down from early estimates of 64% two weeks ago.

The figures, based on data from an unspecified number of people between June 20 and July 17, are significantly lower than previous estimates of the vaccine’s efficacy against other variants, which initial clinical trials found to be 95%.

The Israel findings also conflict with several other studies assessing the vaccine’s performance against the Delta variant, which indicated only slightly diminished degrees of protection against infection and mild illness (between 80% and 90%), including peer reviewed research from Public Health England published Wednesday.

The vaccine still provides very high levels of protection against hospitalization (92%) and severe illness (91%) caused by the Delta variant, the ministry said.

In a statement, Pfizer and BioNTech noted that while real-world data from Israel show vaccine efficacy in preventing infection and symptomatic disease to decline six months post-vaccination, “efficacy in preventing serious illnesses remains high.”

You are equating a vaccinated person who catches it with a person who is vaccinated who catches it being able to transmit it. They are two very different things.

You could have one who catches it and doesn't transmit and another who can. It depends on the viral load and the immunity response which will be different in everyone.

BTW, Carry on cowering.

I'm not, I'm saying that some people who have been vaccinated will not catch the disease in reply to Carths comment.

Nothing more, nothing less.

Interesting footnote in the above link by BenMcr

*Important Notice

medRxiv publishes preliminary scientific reports that are not peer-reviewed and, therefore, should not be regarded as conclusive, guide clinical practice/health-related behavior, or treated as established information.

I'd still be of the opinion that anyone vaccinated can still catch it . . whether that's a 90% chance or a 0.1% chance
