The benefits of the Johnson & Johnson and the Pfizer-BioNTech and Moderna vaccines far outweigh any possible risks, according to new data from The Centers for Disease Control and Prevention (CDC). 

Between February 27 and June 30, 12.6 million Johnson & Johnson vaccine doses have been administered. There were only 100 confirmed reports of Guillain-Barre Syndrome or GBS, a rare disorder where your body’s immune system begins attacking the nerves.

In the same period, 141 million second doses of mRNA COVID-19 vaccines, Pfizer and Moderna, had been administered in the United States. Out of those 141 million doses, the CDC said they confirmed 497 cases of myocarditis, an inflammation of the heart muscle. Nobody died from vaccine-related myocarditis. 

Overall, the CDC said the report showed the estimated benefits outweigh the risks associated with vaccines. Meanwhile, the CDC is also urging women who are pregnant or breastfeeding to get vaccinated against COVID-19.
