The WHO Told Whether It is Possible to Mix Vaccines Against Coronavirus
OREANDA-NEWS. People do not have to make their own decision about mixing different vaccines for coronavirus, research in this direction is still ongoing. This was announced at a briefing on Tuesday by the official representative of the World Health Organization Christian Lindmeier.
"Clinical studies that are being conducted by the University of Oxford are still going on to understand the interactions between the AstraZeneka and Pfizer vaccines. And these studies also included the Moderna and Novovax vaccines. Preliminary evidence suggests that people who received the first dose of AstraZeneka and then with a second dose of Pfizer, they are more susceptible to mild fever and other moderate side effects than those who receive the full AstraZeneka vaccine,” he said.
According to him, this is a study that was conducted among people over the age of 50. Lindmeier also stressed that people themselves, without a doctor's recommendation, "should not make decisions about mixing different vaccines."
However, as RIA Novosti reported earlier, citing data from the University of Oxford, mixing vaccines against coronavirus produced by AstraZeneca and Pfizer forms immunity against COVID-19 in humans.
"Tests conducted at the University of Oxford as part of the Com-COV study showed that the combined use of Pfizer and AstraZeneca vaccines led to the generation of a strong immune response against COVID-19," the university said in a statement.
Different combinations were used during the study: the first dose was from AstraZeneca, the second was from Pfizer, and vice versa. Scientists note that all of them "can be effectively used to protect against COVID-19", which will give more flexibility in vaccination. The university has promised to publish the test results at 12-week intervals.
