Using weekly data on excess mortality in New Zealand, a study published last week set out to analyse the impacts of rolling out booster doses of Covid injections. It found that age groups most likely to have had booster Covid injections had 7-10% more excess mortality than the age groups most likely not to have taken up a booster dose.
“The results suggest 16 (95% CI: 5 to 27) excess deaths per 100,000 booster doses, amounting to over 400 excess deaths in New Zealand given the booster doses administered to date. If this rate of excess deaths is extrapolated to other countries, it amounts to over 300,000 excess deaths worldwide,” Professor John Gibson, the study’s author, wrote.
The study was published in EconPapers, the world’s largest collection of on-line economics working papers, journal articles and software, and authored by John Gibson, Professor in the Department of Economics at the University of Waikato, Hamilton, New Zealand.
In his paper, ‘The Rollout of COVID-19 Booster Vaccines is Associated with Rising Excess Mortality in New Zealand’, Prof. Gibson stated:
“The ratio of vaccine risk to benefits likely has swung more towards risk than during the original randomised trials, due to dose-dependent adverse events and to fixation of immune responses on a variant no longer circulating.
“In light of an unsatisfactory risk-evidence situation, aggregate weekly data on excess mortality in New Zealand are used here to study the impacts of rolling out booster doses.
“The age groups most likely to use boosters had 7-10 percentage point rises in excess mortality rates as boosters were rolled out while the age group that is mostly too young for boosters saw no rise in excess mortality.”
