Vaccination campaign responses
Early reports of the events of concern seemed to indicate the presentation rate for the specific blood clots of concern might be higher for women of younger ages, UK Medicines and Healthcare products Regulatory Agency (MHRA) found examples across all genders and ages, their data skewing towards these specific blood clots being more prevalent in AZD1222 vaccinated persons of younger ages.The WHO has continued to stress the administration of vaccines is based on risk versus benefit analysis. Some variables that may be factored into such analysis include risk of an individual from catching COVID‑19, which relate to the infection rate in that area, and the benefits to that individual if vaccinated and exposed to COVID‑19 which varies with age, versus whatever the risks of vaccination are to that individual.
