PHARMACY customers who report feeling unwell after their COVID-19 jab may have a better immune response, according to US researchers.
The study, published in Annals of Internal Medicine, looked at 363 people in the US who had not been vaccinated against, or exposed to, COVID-19, who then received two doses of the Pfizer or Moderna vaccine.
They found short-term side effects after the second dose, such as chills, tiredness, feeling unwell, and headache, were associated with a 1.4- to 1.6-fold higher immune response at one and six months after a COVID-19 vaccination.
Each degree increase in skin temperature after the second vaccination dose was also linked with a 1.8-fold higher response a month later, and a 3.1-fold higher response six months later.
The authors believe their study's findings may be relevant in addressing negative attitudes toward vaccine side effects, which are a barrier to vaccine uptake.
