On the wild ride to the vaccine this also happened: the UK decided to change dosing protocols.
What does that mean? The national health agency has made it a priority to extend the first injection to as many people as possible, delaying the administration of the second dose beyond the times established by science.
A winning move, against the growing infections with the English variant, or a dangerous gamble? That is why vaccination against Covid in the UK runs the risk of being a failure.
In the UK, vaccination changes the rules
More than 500,000 people who have been vaccinated against Covid-19 they will see theirs second dose delayed up to 12 weeks in the United Kingdom. the NHS in fact, it has revised injection rules with the goal of stopping the nation’s growing number of coronavirus victims.
This change, of course, means that priority will now be given to giving as many people the first dose of Oxford-AstraZeneca and Pfizer-BioNTech vaccines, in order to maximize the number of immunized. The available vaccine, in fact, will be used for the first puncture, not counting the doses needed for the second.
Recipients will continue to receive both doses to confer full immunity, but now the second will be delayed, in most cases 11-12 weeks after the first. The protocol provides for a four week period between the two injections.
Will the plan really be effective? Not a few experts and doctors doubt the strategy.
Why the UK is at risk of vaccine failure
As London celebrates the announcement of 2 million AstraZeneca doses per week in mid-Januaryon the other hand, reflections on the decision to delay the second dose increase.
Science is skeptical, as experimental studies on the Covid vaccine have shown its full functionality thanks to the antibodies developed with both doses. Extending the second injection three months after the first can result in a higher chance of infection while you wait for the final dose.
Anthony Fauci expressed all his disappointment: “I am not in favor and in the United States we will continue doing what is being done”.
Similar opinion from Italian Massimo Galli, from the Sacco Hospital in Milan:
“Efficacy was tested on the basis of a protocol. his [ gli inglesi] they are not following the instructions and this method may be fine, at which point they will have won the lottery, or it can go wrong, with the risk that some people who were not enough with the first dose of vaccine reinfect“
