When it comes to protection over time, some COVID-19 vaccines perform better than others, according to a UCSF study.
Hundreds of thousands of people in the Bay Area who rolled up their sleeves for a COVID-19 shot received one from Johnson & Johnson, Moderna or Pfizer.
Boost Study researchers at UCSF looked at nearly 500 healthy volunteers before and after they received a COVID shot and found that different vaccines offered varying degrees of protection. Senior author Dr. Elissa Epel said people who received the Johnson & Johnson vaccine experienced growing protection over time.
“What was surprising was that six months later, those who had the J&J vaccination also had an increase in their level of their neutralizing antibodies," said Epel."So that by six months, they were just as good as the other vaccinations. They had surpassed the level of antibodies in those who had the Pfizer vaccination."The study also found other factors played a role in vaccine effectiveness.
