New study suggests Covid boosters have “negative efficacy” and increase infection risk

A recent preprint study has raised concerns about the effectiveness of Covid-19 booster shots, suggesting that they may not only fail to protect against infection but could also increase the risk of contracting the virus over time.

The study focused on healthcare workers in Georgia during the Omicron variant wave, analyzing data from January to June 2022.

According to the study, while the booster provided some protection in the first month, its effectiveness quickly diminished. By the second and third months, the data showed a negative vaccine effectiveness (VE), meaning boosted individuals were more likely to contract Covid than those who had not received the shot. This negative trend worsened by the fourth month after boosting.

Despite the findings the study authors nevertheless advocated for increasing ‘vaccination’ of healthcare workers “prior to periods of anticipated high COVID-19 incidence.”

The study detailed that the absolute VE for a first booster was 40% in the first 7-29 days, but it dropped to -9% after 30-59 days, and plummeted to -46% after 60 days.

The study also noted that the viral vector and mRNA vaccines used to boost immunity stimulate the production of the spike protein, which may explain why individuals test positive after receiving repeated doses. Additionally, the research suggested that repeated vaccinations could increase lethality and infection rates over time.
