Mixing Corona Vaccine is not a reckless design, here's the proof


A number of countries have implemented combined or mixed Corona vaccine strategies. This is not a reckless plan, but there is a scientific basis.
The combination vaccine is to give 2 types of Corona vaccine, each for the first and second injection. The aim is to establish immunity to the various COVID-19 variants currently available.



The most commonly combined are AstraZeneca and Pfizer. While seemingly reckless and trial-and-error, this strategy has a scientific basis.





According to Dr. Amesh Adalja of Johns Hopkins University Health Safety Center, this method is called heterological prime enhancement vaccination. This method has been done before.



"In previous studies of the bird flu virus, it used a major heterological impetus and this was part of the research agenda to try and optimize the vaccine," Adalja told CNN as seen on Monday (12/7/2021).



Adalja said it will still take months to years to make the perfect Corona vaccine in the future. The important thing now is to make the second generation vaccine better.



“The important thing is to understand how to make better second -generation vaccines and use this knowledge to improve other vaccines for other infectious diseases,” he said.



Adalja says the immune response is different from each Corona vaccine. This is because each Corona vaccine uses a different technology.



"This is an important area of ​​research to better understand and plan vaccine lines," he said.



One of the drivers is research published in the Annals of Internal Medicine that states that people with organ transplants do not have good immunity after being vaccinated against Corona twice. However, a third vaccine injection appears to have successfully triggered immunity
