All the vaccines are highly effective at preventing COVID-19.
It’s important to note that an accurate comparison of all three vaccines is difficult to produce, as the Johnson & Johnson trials occurred when variant strains of the virus had been introduced to the population. The Pfizer and Moderna vaccines were tested before this was the case. However, recent tests have found that 2 doses of the Pfizer vaccine has an effectiveness between 64% and 95% against the Delta variant.
In clinical trials, the Pfizer vaccine was 95% effective against COVID-19, while the Moderna vaccine was 94% effective. The Johnson & Johnson vaccine was 90% effective in tests conducted in the US.
All three vaccines perform exceptionally well in reducing severe cases, limiting hospitalization and death almost entirely. All three will save countless lives.
*Please note that on April 23, 2021, the FDA and CDC recommended the use of the Johnson & Johnson’s Janssen COVID-19 Vaccine.
