There are still 20 vaccines in phase 3 trials, eight approved for limited use — Bahrain granted emergency approval to Johnson & Johnson’s vaccine this week — and four approved for full use in some countries. The fully approved vaccines include those from Pfizer/BioNTech, Sinopharm, Sinovac, and Moderna.
The big vaccine news this week is that Johnson & Johnson’s vaccine is poised to receive emergency use authorization in the United States following today’s Food and Drug Administration (FDA) advisory panel meeting. In Africa, the rollout of the United Nations-backed COVAX effort to distribute vaccines to less wealthy countries began.
Vaccines are being rolled out in many nations, but access to vaccines and vaccination rates vary widely around the world. Many countries have not vaccinated a single person yet. Israel, with 35.8% of its population fully vaccinated, is the leader in the global rollout, followed by Seychelles and Serbia. The United States is fourth, with 6.5% of its population fully vaccinated (down from third place last week). The vast majority of countries, however, have not yet received any vaccines.
FDA releases positive analysis on Johnson & Johnson’s vaccine
On Wednesday, the FDA released an analysis showing that Johnson & Johnson’s vaccine is safe and effective. The overall effectiveness of the vaccine in the United States was 72%, and in South Africa, where a more transmissible variant has been circulating, its overall effectiveness was 64%. Johnson & Johnson’s vaccine is highly anticipated because it doesn’t require regular refrigeration and is administered in only one dose, unlike the Pfizer and Moderna vaccines. Today, experts from outside the FDA will decide whether to recommend the vaccine for emergency use authorization in the United States.
