COVID breakthrough infections occur when a fully vaccinated person catches the disease. But they may be asymptomatic, have mild symptoms and recover at home, or require treatment in hospital. A United States study investigated medical records and published their preprint report on August 29, 2021. Their headline finding is vaccinated people are 17 times less likely to require hospitalization.
The Data is Convincing and Hard to Argue Against
The data in the study covers the period between January and June 2021, and includes 67,311 patient records. The Delta variant was spreading rapidly during this period, and average Americans were beginning to take vaccinations more seriously. COVID-Net Associated Hospitalization Surveillance Network reported the following trends at that time:
1… 87.6% of hospitalized patients had no vaccination against COVID-19.
2… 5% had their first vaccine dose less than 14 days before hospitalization.
3… 4.4% received their second vaccine dose less than 14 days before hospitalization
4… 3.0% received their second vaccine dose more than 14 days before hospitalization
COVID breakthrough infections therefore only occurred in 3% of people entering hospital with full vaccination. This is powerful evidence of the effectiveness of Pfizer, Moderna, and Johnson & Johnson vaccines.
The Demographics Behind COVID Breakthrough Infections
The researchers examined the records of 4,732 hospitalized patients with confirmed COVID-19 in more detail.
1… 93.8 % (4,440) were unvaccinated, and 6.3% (292) fully vaccinated.
2… The average time span from vaccination to hospitalization was 42 days.
3… Vaccinated breakthroughs were significantly older than unvaccinated parents.
3… Vaccinated breakthroughs were more likely to be from long-term care facilities.
4… They were also more likely to have neurological or gastrointestinal complications.
5… Fully vaccinated patients had significantly lower intensive care rates, and deaths.
News Medical.Net concludes ‘The study findings reveal that COVID-19 vaccines can provide significant protection against severe disease in adults and older adults. Overall, they highlight the importance of vaccination in reducing the risk of severe COVID-19, and associated hospitalization.’
