A recent study found that individuals who received the Moderna COVID-19 vaccine had higher levels of antibodies against the Delta variant compared to those who received the Pfizer-BioNTech vaccine. The study also showed that antibody levels were significantly lower in individuals who only received one dose of either vaccine. This suggests that receiving both doses is crucial for optimal protection against the Delta variant.
