A number of recent studies have focused on COVID-19 vaccine efficacy, hospitalization trends and variants.

Here are 15 findings from studies published since March 3:

  1. Pfizer said March 11 that its COVID-19 vaccine prevented 94 percent of asymptomatic cases.
  2. Novavax’s COVID-19 vaccine candidate was 96.4 percent effective in preventing COVID- 19 in its phase 3 K. trial.
  3. Eli Lilly said March 10 its COVID-19 antibody cocktail reduced the risk of hospitalization and death by 87 percent during a recent phase 3.
  4. GlaxoSmithKline and Vir Biotechnology said March 10 that their COVID-19 antibody drug was 85 percent effective at reducing virus-related hospitalizations and death in a phase 3 clinical trial.
  5. Despite few hospitalized COVID-19 patients having a bacterial infection, 52 percent of hospitalizations led to at least one antibiotic prescription, according to the Pew Charitable Trusts’ Antibiotic Resistance Project published March 10.

People who received both doses of Pfizer-BioNTech’s messenger RNA vaccine and had no symptoms had an 80 percent lower risk of testing positive for COVID-19 compared to those who were unvaccinated, according to research published March 10 in Clinical Infectious The findings suggest mRNA vaccines are effective at reducing the risk of asymptomatic infection.

  12. Both Pfizer’s and Moderna’s COVID-19 vaccines were at least 10 times less effective against a virus variant first found in South Africa in a small study conducted by researchers from Columbia University, Business Insider reported March 8.
  13. In-hospital mortality for COVID-19 patients fell 15 percentage points from March to August 2020, according to a study published March 5 in JAMA Network Open.
