Purpose: In this paper, we will analyze the side effects of the 4 popular Covid-19 vaccines (Moderna,
Pzer, Johnson & Johnson, AstraZeneca) and compare the population groups involved in each vaccine
trial. With the availability of these 4 different vaccines, people are trying to understand the differences in the side effect prole of
each vaccine. We have attempted to collect data from the different publicly reported sites which include information about the
various trials for each vaccine and pull all the numbers in one place to help the readers compare for themselves.
Method: We collected data relating to the side effects of each vaccine from the Fact Sheet for Health Care Providers EUA
published by the FDA for each vaccine as well as data from the Phase 1-2a trial of the AstraZeneca vaccine published by the
Lancet.

Results: The common side effects after the vaccines such as headache, fatigue, nausea, pain, swelling at vaccine site, fever
was compared between different vaccine groups as well as between various age subgroups in each vaccine group. Then we
focused on the rare side effects associated with each vaccine such as Bell's Palsy with Pzer and Moderna vaccines and
thromboembolic events with J&J vaccine and transverse myelitis in the Astra Zeneca vaccine. The side effect rate in each
vaccine and placebo group is included in the data.
Conclusion:In effect all vaccines are found safe with incidence of the rare and serious adverse events being extremely low and,
in some cases, extremely difcult to say whether the adverse event could actually be attributed to the vaccine or to chance given
the actual incidence of the disease in the general population.
