4 hours agoStudy: Pfizer and AstraZeneca mix provides strong protection against COVID-19

(5 years ago)Early Results From a British Anti - Inocation Study COVIDD-19, suggests that mixing various vaccine firms may provoke an immune defensive response against the coronavirus. On the test, volunteers produced high levels of antibodies and immune cells after receiving a dose of Pfizer vaccine and an AstraZeneca dose. Management [...]
The management of vaccines in each way is likely to provide powerful protection, Dr. Matthew Snape, a vaccine expert at Oxford University, at a press conference Monday.
“Any of this, I think it can be argued, would be expected to be effective,” he said.
Dr. Snape and his colleagues started studying, called “Com-COV”, in February of this year, follows Clankosova.tv.
In the first wave of the study, they gave the 830 volunteers one of the four combinations of vaccines. Some took two doses of Pfizer or AstraZeneca, both proved effective against COVID-19.
Others received a dose of AstraZeneca, followed by a Pfizer, or vice versa.
For the first wave of volunteers, scholars waited four weeks among the doses. Studies have found that AstraZeneca vaccine provides stronger protection if the second dose is delayed by 12 weeks, so researchers are also conducting a special 12-week test that should yield results next month, reports The New York Times.
The study also found that the use of various vaccines produced a higher level of immune cells affected to attack the coronary than by giving two doses of the same vaccine. Dr. Snape said it was not yet clear why the mix had that advantage.
The “is really very intriguing”, he said.
Dr. Snape and his colleagues have started a similar study, adding vaccines from Modernna and Novavax.
