Recent research has suggested mRNA vaccines will last longer than traditional vaccines (like the J&J vaccine that has actual Covid-19 in it). The Pfizer and Moderna vaccines have also shown protection against variants such as the delta variant.

According to Dr Ali Ellebedy, an immunologist at Washington University in St. Louis: “The fact that the reactions continued for almost four months after vaccination — that’s a very, very good sign,” Dr. Ellebedy said. Germinal centers typically peak one to two weeks after traditional immunization, and then wane. This has not been the case with mRNA vaccines.

“Usually by four to six weeks, there’s not much left,” said DR Deepta Bhattacharya, an immunologist at the University of Arizona. But germinal centers stimulated by the mRNA vaccines are “still going, months into it, and not a lot of decline in most people.”

Here is a comparison of the mRNA vaccines to traditional vaccines:
