The WHO indicated that there is not enough information on the benefits of mixing or combining vaccines. At the same time, he stressed that the effectiveness of a third dose of an immunizer has not been proven so far.
The World Health Organization (WHO) warned about the tendency to mix or combine vaccines against Covid-19 and assured that it is a technique that could be dangerous and whose decision must be made by experts.
Soumya Swaminathan, WHO chief scientist, said there are people who are thinking about mixing and matching immunizers. We’ve seen a lot of inquiries from people who say they’ve had one (vaccine) and plan to get another. However, it is a somewhat dangerous trend. People are in a zone with no data or evidence when it comes to mixing and matching. There is limited data on these practices, there are ongoing studies but we have to wait. “
Another of the warnings issued by the WHO has to do with the use of a possible third dose of a drug. Some leaders and experts have indicated that an additional dose of a vaccine would serve to reinforce the effect once the antibodies have begun to decrease, however, the agency assured that information on the benefits or harm of this practice is also lacking.
Ann Lindstrand, from the WHO Essential Immunization Program, explained that “our group of strategic advisory experts is definitely looking at any evidence that emerges on the need and use of booster doses, but at this time there is not enough data to point to the importance of those doses, and less so now that the global supply is limited ”.
In turn, he noted that “it is important to rethink whether any country is considering increasing and using booster doses, and instead think about giving that supply or sharing that supply with countries that have not even inoculated their health workers.”
