Covid Vaccines: What We Know About Mix And Match

Covid Vaccines: What We Know About Mix And Match

The covid vaccines remain in the spotlight and a new subject raised involving them: the mixing and matching between various covid vaccines.

This week, an expert committee that advises the Centers for Disease Control and Prevention will hear about the results of a clinical trial that could be influencing the way in which Covid vaccines are used in this country at some point in the future.

It’s been revealed that the trial was conducted by the National Institute of Allergy and Infectious Diseases – this included a so-called mix-and-match trial, testing the Covid vaccines authorized in the U.S. in combinations with each other.

StateNews revealed that the goal of the trial was to see whether using a different vaccine as a booster shot improves protection against the disease triggered by the novel coronavirus. 


“So does getting a dose of Pfizer vaccine after getting a single dose of Johnson & Johnson’s vaccine trigger production of more antibodies than a second dose of the J&J would? Are the messenger RNA vaccines made by Pfizer and Moderna virtually interchangeable, or does switching even there produce a broader set of immune responses?” – these are the questions that the online publication mentioned above posed in their article.

They also noted the fact that the booster shot most vaccinated Americans are in the process of getting or booking may not be the last needed.

This means that learning how to optimize use of the current generation of Covid vaccines is critical, according to more experts. 

The publication continued and analyzed the terminology around the booster shots, and they also made sure to highlight that not all combos are created equal. We suggest that you take a look at the original article in order to learn all the available details about the covid mixing and matching vaccines.
