What is the news?
The researchers are still working to understand how long their protection lasts, and how it differs from one person to another. Getting answers to these questions is a crucial step to determine who will need a booster shot.
The studies have found that the Moderna Vs Pfizer vaccines have certain subtle differences.
About the difference between Moderna and Pfizer vaccines
Studies have been conducted on Pfizer and Moderna vaccines. The studies show that Pfizer’s vaccine offers less protection than Moderna’s vaccine. Moreover, researchers found an inferior response to the Pfizer vaccine in people 50 and older.
One theory about Moderna’s vaccine is that it creates more antibodies because it uses a larger dose.
Another theory is regarding long-term immunity. That longer-term protection, which includes T cells and memory B cells, is harder to measure in the lab than antibodies.
Significance of the studies
These studies will help in developing long-term policies for vaccination and aid further research. This will go a long way in securing the health of the public at large.
None of the studies measured whether fewer antibodies results in less protection overtime or not.
