Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Last I heard (Feb 2021) the Tories were violating vaccination protocol by giving as many first shots as they could and not following-up with the same number of second shots.  This allowed them a propaganda victory.  The medical results however are suspect.  Not putting a person through the whole course of intervention is the classic way for a pathogen to become resistant to the intervention.

Yes, they're allowing a 12 week gap between shots, when the trial data is based on a 3-4 week gap. I actually think there is a legitimate epidemiological case for this, as studies indicate even the first dose of the Pfizer vaccine offers a very high level of protection, whereas the second dose only boosts this by 10% or so.

If that is the case, and you get one person 85% protected with 1 shot, it may make sense to delay the second shot and give it as a first shot to someone else who will be 85% protected rather than boosting the first person by only another 10%.

From an individual point of view, you want to get max protection asap, but from a herd immunity perspective, you get more bang for you buck by spreading the doses more.

Of course medical opinion is divided on this and we won't be sure what is the most effective strategy for some time yet. But to me it seems getting as many people 85% protected as possible ASAP is a better strategy to avoid further spread.

Pfizer and Moderna are 80% effective after the first dose and 94-95% effective after the second.  

At least according to the Infotainment Mediums.  I haven't been able to track down the (supposed) CDC study the Infotainment Reports are (supposedly) reporting.  Given journalists and editors exhibit almost total ignorance of science and technology take with salt.

Messenger RNA (mRNA) COVID-19 vaccines have been shown to be effective in preventing symptomatic SARS-CoV-2 infection in randomized placebo-controlled Phase III trials

The findings complement and expand upon these preceding reports by demonstrating that the vaccines can also reduce the risk for infection regardless of COVID-19-associated illness symptom status (4,5). Reducing the risk for transmissible infection, which can occur among persons with asymptomatic infection or among persons several days before symptoms onset (6), is especially important among health care personnel, first responders, and other essential and frontline workers given their potential to transmit the virus through frequent close contact with patients and the public.

(My) conclusion: vaccination does limit virus shredding by a-symptomatic persons and prevent high level of infection.

Thank you.
