COVID-19, yeni koronavirüsün neden olduğu oldukça bulaşıcı bir hastalıktır. İlk olarak 2019’da Çin’in Wuhan kentinde tanımlandı ve o zamandan beri küresel bir salgın haline geldi. COVID-19 semptomları hafif ila şiddetli arasında değişebilir ve ateş, öksürük ve nefes almada zorluk içerebilir.
Yeni bir çalışma, aşı yanıtları ile daha yüksek antikor konsantrasyonları arasında bir bağlantı buldu.

The study was conducted on a large group of healthcare workers. Previous research has shown that concerns about potential side effects and a belief that the vaccine is not effective are the main reasons why some individuals refuse to be vaccinated against COVID-19.
The study also examined the relationship between the occurrence of side effects and the measured antibody concentrations.
Significantly higher antibody levels were seen 14 weeks after vaccination with two doses of Comirnaty and especially after a heterologous vaccine sequence Vaxzevria-Comirnaty compared with two doses of the Vaxzevria vaccine. Antibody concentrations were significantly higher in people younger than 30 than in older subjects.
In most subjects, vaccine reactions developed that were mostly rated as mild to moderate. Local adverse effects were most commonly reported, followed by systemic reactions, such as fatigue/exhaustion/malaise, headache, and musculoskeletal pain.
The authors concluded that vaccinations against COVID-19 lead to significantly higher antibody concentrations in persons with vaccine reactions. The vaccines used were altogether well tolerated.
