Summary
This study tested an extra dose of the PHH-1V COVID-19 vaccine in 241 adults with weakened immune systems (due to HIV, kidney disease, or autoimmune conditions) who had already received other COVID-19 vaccines. The goal was to see if the booster increased their antibody levels against different virus variants and was safe. Results help determine if this vaccine can better protect immunocompromised people.
