Diagram of By six compared to two doses of AstraZeneca, a new, unpublished South Korean study relayed by . Patients who received two doses of On the other hand it has a level Similar to the mixed vaccination schedule.in a dose Followed by a dose of Pfizer / BioNTech increases the level
This result confirms the results of several other studies. in June, (in pre-release), for example, showed that an injection of AstraZeneca followed by Pfizer resulted in a better response to T from all other combinations. Another study In May also reports a “significantly increased” immune response compared to the control group (after receiving only one dose of AstraZeneca).
Quite logical conclusion from an immunological point of view: “ frequent doses of , immunology inImperial College from London. In addition, the two technologies stimulate a different immune response: Vaccines like AstraZeneca are known to stimulate so-called killer T cells, which destroy infected cells. the They are good for antibody production “,” And in Val-de-Grâce and specializes in vaccination.Based on Like the ones from Oxford-AstraZeneca tend to be less effective, because Develops a response against the adenovirus itself “,”
Confusion between Pfizer and Moderna vaccines increases side effects
As a result of rare cases of People under 55 years of age They were asked to switch to the RNA vaccine for their second dose in France. Article published in I considered this strategy, which has not yet been the subject of any studies on its efficacy and safety. Verdict: The vaccine mixture, even if it turns out to be completely safe for health, stands out .
The Oxford University study included 830 patients who were vaccinated according to four schedules: AstraZeneca followed by Pfizer, Pfizer followed by AstraZeneca or just one or the other. 34% of patients reported receiving a dose of AstraZeneca followed by PfizerAfter the second injection, compared to 10% of those who took AstraZeneca only. People who have had multiple vaccinations also experience more fatigue, headaches, and . Fortunately the effects are temporary but require further investigation, according to the researchers.
In April, it was He has seen that the vaccination schedule is of a type” Heterogeneous “(consisting of mixing vaccines) was” More effective than identical primary augmentation approaches (exactly identical injections) in phase 1 and 2 studies in humans. Perhaps one way to justify continuing , while its use was extended to all adults in Germany, boosting the vaccination campaign.

With the arrival of life-saving vaccination campaigns, . Can I get a first dose of one vaccine and a second dose of another vaccine? To this last question, health authorities provide an accurate answer. where is the Vaccines controlled by the United States , English officials, believe that Pfizer and AstraZeneca – the two main formulas distributed in the country – could be used in a supplemental way if necessary.
« Every effort must be made to give [aux patients] the same vaccineAnd responsible for vaccinations, But when that is not possible, it is better to give them a second dose of another vaccine than not to give them any at all. Although different techniques are used, both Pfizer and AstraZeneca formulas stimulate an immune response against from climax Which leads the authorities to consider the combination of the two as low risk. However, on the part of the researchers, if the proposal of the English authorities is likely to succeed, the strength at the moment is the recognition of the lack of data on the subject. Therefore, experts recommend at all costs to avoid mixtures until further studies are carried out: !
