Hypothesis
What are the neutralizing antibody levels in healthcare workers in Taiwan after receiving different COVID-19 vaccines?
Conclusion
Heterologous prime-boost vaccines and two doses of mRNA vaccines are recommended for better neutralizing antibody levels.
Supporting Evidence
- Vaccination with AZD1222 + mRNA-1273 produced higher neutralizing antibodies than AZD1222 + AZD1222.
- Neutralizing antibodies were associated with vaccine side effects, including fever, headache, and myalgia.
- Underlying diseases like hypertension and cancer reduced neutralizing antibodies after vaccination.
Takeaway
This study found that mixing different COVID-19 vaccines can help healthcare workers in Taiwan build stronger defenses against the virus.
Methodology
A prospective observational study measuring neutralizing antibodies in healthcare workers after two doses of COVID-19 vaccines.
Limitations
The study did not analyze the immune responses against new SARS-CoV-2 variants.
Participant Demographics
The study included 514 healthcare workers, with a median age of 41 years, consisting of 45 males and 468 females.
