  • RE: Is it Sensible to Restrict AstraZeneca by Age?

    All vaccines have side effects, some more so than others, especially when clinical laboratory trials and development of vaccines for COVID-19 have progressed at warp speed.

    A small number of AstraZeneca vaccine recipients have been found to experience rare blood coagulation, especially for women under 65 years, and low platelet counts, especially for individuals recently injected with a specific batch, so much so that its safety has been called into question.

    A number of countries have restricted the vaccine to those above a certain age, be it 50, 55, or 60 years of age, as younger cohorts seem to have a greater risk of blood clotting.

    The added presumption that younger adults are less likely to be infected by COVID-19 has been belied by the findings that the mutated strain, variant, or lineage from Brazil has targeted those aged from 18 to 45 years, with more highly transmissible, infectious, contagious, and deadly effects than the original wild-type coronavirus (COVID-19).

    Several national risk assessment panels and medical societies have approved the safety of the vaccine, especially in comparison with the damaging consequences of not being vaccinated against COVID-19.

    Unlike some European countries, the UK has not reported an unexpected number of vaccinated patients suffering from blood clots, although evidence has not been presented according to age.
