Is Moderna COVID vaccine better than Pfizer Vaccine?

Are all COVID Vaccines equally effective ?

Probably not.

But until recently there has been hardly any direct clinical studies comparing different vaccines.

A recent study conducted in Belgium compared the Moderna and Pfizer COVID vaccines.

The study looked at antibody responses following vaccination in Health care workers. Antibody levels were measured prior to vaccination as well as 6 to 10 weeks after the second dose.

Higher antibody levels were observed in people vaccinated with Moderna vaccine compared with those vaccinated with Pfizer vaccine.

Future research is needed to see how these differences affect the general population.

Both Moderna and Pfizer vaccines are based on same technology (mRNA based vaccines).

If significant differences exist between between vaccines of same technology, then it is likely that differences would exist between vaccines of different technology (eg Pfizer vs Astra Zeneca).

The public health authorities would need to decide whether booster vaccinations should be done with a different vaccine.
