Topline
Oxford University will lead first trial examining whether different Covid-19 vaccines can be used interchangeably, the University’s vaccination group said Thursday, an effort that could make vaccination programs more flexible and even more protective better anti-disease.
The UK is testing a combination of different types of Covid-19 vaccine.

Key facts
The study, run by the UK National Vaccination Register Assessment Consortium, employs more than 800 people over 50 years to assess the feasibility of using a single vaccine for the first “primary” view and one between for the second “boost” bullet.
The lawsuit will initially use the Oxford-AstraZeneca and Pfizer-BioNTech vaccines, both of which have already been cleared for use in the UK, and others that may be added later. forward.
Britain’s Deputy Chief Medical Officer, Jonathan Van-Tam, said the lawsuit would provide “more insight” into the use of vaccines against Covid-19, and provide data that could support provide a “more flexible vaccination program” in line with global supply chain issues.
“It is possible that even by combining vaccines, the enhanced immune response could lead to even higher antibody levels that last longer,” Van-Tam said.
The study will also assess the effectiveness of different vaccine compounds when the bullet is administered after different intervals: one after four weeks and another after 12, which is the standard UK approach in an attempt. to give some people some sort of protection as soon as possible.
If the results are promising, the UK government said it would consider changing its national vaccination strategy.

Professor Matthew Snape, Oxford’s chief investigator of the trial, said: “This is a very interesting study that will provide vital information for the distribution of vaccines in the UK and around the world… If we show that these vaccines can be used interchangeably in the In the same table this will greatly increase the flexibility of vaccine delivery, and could provide advertisements on how you can extend the scope of protection against strains increase the number of new viruses. “
Tangent
Some vaccines work best if a different vaccine is used to enhance the picture, called a heterologous augmentation. Russia’s Sputnik V vaccine, which early studies show is 92% effective in inhibiting Covid-19, uses the principle. It uses a different modified virus in each bullet to carry the immune guidance into the body.
