Healthy Vaccinee Bias and MenB-FHbp Vaccine Effectiveness Against Gonorrhea.
Abara WE, Bernstein KT, Lewis FMT, Pathela P, Islam A, Eberhart M, Cheng I, Ternier A, Sanderson Slutsker J, Madera R, Kirkcaldy R. Abara WE, et al. Sex Transm Dis. 2023 Jun 1;50(6):e8-e10. doi: 10.1097/OLQ.0000000000001793. Epub 2023 Mar 2. Sex Transm Dis. 2023. PMID: 36863060
Observational studies demonstrated 30% to 40% effectiveness of outer-membrane vesicle (OMV) meningococcal serogroup B vaccines against gonorrhea. To explore whether healthy vaccinee bias influenced such findings, we examined the effectiveness of MenB-FHbp, a …

Frequency and impact of confounding by indication and healthy vaccinee bias in observational studies assessing influenza vaccine effectiveness: a systematic review.
Remschmidt C, Wichmann O, Harder T. Remschmidt C, et al. BMC Infect Dis. 2015 Oct 17;15:429. doi: 10.1186/s12879-015-1154-y. BMC Infect Dis. 2015. PMID: 26474974 Free PMC article. Review.
However, these studies are prone to confounding by indication and healthy vaccinee bias. We aimed to systematically investigate these two forms of confounding/bias. ...Of these, 19 (83 %) showed high risk of bias: Fourteen due to confounding by …

Does the healthy vaccinee bias rule them all? Association of COVID-19 vaccination status and all-cause mortality from an analysis of data from 2.2 million individual health records.
Fürst T, Bazalová A, Fryčák T, Janošek J. Fürst T, et al. Int J Infect Dis. 2024 May;142:106976. doi: 10.1016/j.ijid.2024.02.019. Epub 2024 Feb 22. Int J Infect Dis. 2024. PMID: 38401782 Free article.
OBJECTIVES: We investigated the validity of claims of the healthy vaccinee effect (HVE) in COVID-vaccine studies by analyzing associations between all-cause mortality (ACM) and COVID-19 vaccination status. ...

Effectiveness of a fourth SARS-CoV-2 vaccine dose in previously infected individuals from Austria.
Chalupka A, Richter L, Chakeri A, El-Khatib Z, Theiler-Schwetz V, Trummer C, Krause R, Willeit P, Benka B, Ioannidis JPA, Pilz S. Chalupka A, et al. Eur J Clin Invest. 2024 Mar;54(3):e14136. doi: 10.1111/eci.14136. Epub 2023 Nov 30. Eur J Clin Invest. 2024. PMID: 38032853
DISCUSSION: In previously infected individuals, a fourth vaccination was not associated with COVID-19 death risk, but with transiently reduced risk of SARS-CoV-2 infections and reversal of this effect in longer follow-up. All-cause mortality data suggest healthy vaccine …

Influenza vaccination for all pregnant women? So far the less biased evidence does not favour it.
Donzelli A. Donzelli A. Hum Vaccin Immunother. 2019;15(9):2159-2164. doi: 10.1080/21645515.2019.1568161. Epub 2019 Feb 20. Hum Vaccin Immunother. 2019. PMID: 30632885 Free PMC article. Review.
Pregnant women are a WHO priority group for influenza vaccination, but evidence from observational studies in pregnancy is subject, among others, to the healthy-vaccinee bias, overestimating the vaccine effectiveness and safety. An USA survey adds new evidenc …

Beneficial non-targeted effects of BCG--ethical implications for the coming introduction of new TB vaccines.
Roth AE, Stensballe LG, Garly ML, Aaby P. Roth AE, et al. Tuberculosis (Edinb). 2006 Nov;86(6):397-403. doi: 10.1016/j.tube.2006.02.001. Epub 2006 Aug 8. Tuberculosis (Edinb). 2006. PMID: 16901755 Review.
Studies of the effect of BCG on morbidity in humans are scarce; some found a positive effect of BCG and others show no effect. Non-targeted effects of vaccines-possible bias and confounding: The major argument against comparing vaccinated and unvaccinated groups is that th …
