Study model says COVID boosters effective against infection

Three boosters a year is the magic number according to a new model, but much work is needed.

In the process of reviewing a yet-to-be fully peer-reviewed preliminary scientific report that is a model-based analysis of the impact of vaccination frequency on COVID-19 public health outcomes, biostatisticians learned what they suspected from real world data suggests the team lead at the Civil Society Partners Against COVID-19 tracking team in Singapore.

Roughly 90% population-adherence to booster doses every three months is what’s needed, predicted a new study model, to inhibit spread of even the highly transmissible new Omicron variants. (Study DOI:

Key Take-aways from this preliminary data imply safety and efficacy studies of high frequency vaccine boosters are needed.

  1. The goal of vaccination and boosters is a robust and durable antibody response to reduce infections and mitigate the death and disability outcomes of COVID-19.
  2. Future COVID-19 vaccines need to have equal or higher efficacy than natural infection.
  3. Three booster doses of the aforementioned future vaccines in each year are indicated by the study model to provide complete protection against infection among already vaccinated individuals. A vaccinated individual is defined as having received an initial injection followed by a secondary injection at a prescribed interval which interval varies with each type of vaccine.

Moms vaccinated during pregnancy have safer babies.

Another study published in the British Medical Journal (BMJ) indicates positive outcomes for babies of mothers inoculated with 2nd or third vaccine doses during pregnancy. The study concludes “maternal covid-19 vaccination with a second dose during pregnancy was highly effective against delta and moderately effective against omicron infection and hospital admission in infants during the first six months of life. A third vaccine dose bolstered protection against omicron. Effectiveness for two doses was highest with maternal vaccination in the third trimester, and effectiveness decreased in infants beyond eight weeks of age.” Published 08 February 2023 (BMJ 2023;380:e074035)

The American Heart Association has reported a significant spike in fatal coronary events due to COVID-19. COVID-19 deaths are likely higher than reported if unexpected coronaries are counted.
