UK Study Shows That Mixing COVID-19 Vaccines Produces a Stronger Immunity!

According to some UK researchers, not only is it safe to mix different vaccines, but it’s actually a better choice!

This is because, apparently, a variety of shots is able to boost your immune system even more than if you just stick with the same vaccine manufacturer for all your doses!

The study involved 1,079 volunteers whose very first shot was either Pfizer or AstraZeneca and they were randomly assigned to get the second dose from the same manufacturer, receive a shot of Moderna or the still experimental Novavax vaccine.

Earlier this week, the team reported that there were no adverse effects caused by the mixing of vaccines.

Another finding was that, regardless of what vaccine the participants received first, getting Moderna as the second one caused a stronger immunity than in the case of those who stuck with the same vaccine.

Furthermore, the best antibody response was achieved by AstraZeneca followed by the Novavax vaccine.

With that being said, given the safety of mixing vaccines and the fact that neither one of these vaccines need special freezer storage, the team of researchers concluded that this might be “extremely relevant to the 94% of people in low-income countries who are yet to receive any doses.”

Of course, this also seems to be a huge discovery that can help patients deal with stronger variants that are more transmissible.

After all, the world is currently worried about Omicron and other variants are expected to emerge as well.

Besides, the winter holidays are upon us and many people need a stronger immune response since they are most likely about to spend more time with extended family and friends from outside their household, leading to more infections.

In the meantime, while the study’s results seem promising, some more peer reviews and further research could be required before the whole world is officially advised to mix-and-match vaccine doses.
