Letter published in “The Lancet Regional Health – Europe”: It appears to be gross negligence to ignore the vaccinated population as a possible and relevant source of transmission when deciding on public health control measures.
Important points from this article noted by the Reinfocovid team are:
- The share of people vaccinated in the transmission of covid -19 is constantly increasing
- Vaccinated people transmit the disease as much as unvaccinated people to their household contacts
- Maximum viral load is the same between vaccinated and unvaccinated
- In the UK, the likelihood of having covid was higher in those who had been vaccinated than in the unvaccinated for all people over 30 years of age.
- In an Israeli cluster caused by a vaccine, 14 vaccinated people had severe forms and some died while the only two unvaccinated people had mild forms.
It appears to be gross negligence to ignore the vaccinated population as a possible and relevant source of transmission when deciding on public health control measures.

Literal translation of the letter:
High rates of COVID-19 vaccination reduce the transmission of SARS-CoV-2 in populations by decreasing the number of possible sources of transmission and, therefore, reduce the disease burden of COVID-19.
However, recent data indicates that individuals vaccinated against COVID-19 count in the transmission of the disease.
In the UK, it has been reported that the secondary attack rate among household contacts exposed to fully vaccinated individuals was similar to that of household contacts exposed to unvaccinated individuals (25% for vaccinated versus 23% for unvaccinated). 12 of 31 infections in fully vaccinated household contacts (39%) were from fully vaccinated and epidemiologically related individuals. Maximum viral load did not differ by vaccination status or type of variant.
In Germany, the rate of symptomatic cases of COVID-19 in fully vaccinated people (“breakthrough infections”) has been reported weekly since July 21, 2021 and was then 16.9% in patients 60 years of age and older. This proportion is increasing week by week and was 58.9% on October 27, 2021 (Figure 1), clearly proving the growing importance of fully vaccinated people as a possible source of transmission. A similar situation has been described for the United Kingdom. Between weeks 39 and 42, a total of 100,160 cases of COVID-19 were reported among citizens aged 60 or older. And 89,821 occurred among fully vaccinated people (89.7%), 3,395 among unvaccinated people (3.4%). A week earlier, the rate of COVID-19 cases per 100,000 was higher in the vaccinated subgroup than in the unvaccinated subgroup in all age groups 30 years or older.
In Israel, a nosocomial epidemic has been reported involving 16 healthcare workers, 23 exposed patients and two family members. The source was a patient fully vaccinated against COVID-19. The vaccination rate was 96.2% among all exposed people (151 health workers and 97 patients). Fourteen fully vaccinated patients became seriously ill or died, the two unvaccinated patients developed mild illness.
The US Centers for Disease Control and Prevention (CDC) identifies four of the five counties with the highest percentage of fully immunized population (99.9-84.3%) as “high” transmission counties. Many policy makers assume that vaccinated people can be excluded as a source of transmission. It appears to be gross negligence to ignore the vaccinated population as a possible and relevant source of transmission when deciding on public health control measures.
