The Covid-19 Actuaries Response Group have recently issued a report on Covid-19 hospitalizations by age and vaccine status, based on data from the UK government’s own reports.
The news is relatively good for fully vaccinated under 50’s, they are far less likely to be hospitalized than older age groups or the unvaccinated, but it’s a very different story for fully vaccinated over-50’s who now make up 52% of all Covid-19 hospitalizations.
Although the over-50s age group has seen a high take-up of the various vaccines available in the UK, they have been hit surprisingly hard by vaccine waning, and a third vaccination in just eight months is now being rolled out for this age group, a measure also introduced in Israel recently.
Janssen’s Covid-19 vaccine recipients reported the largest number of Covid-19 breakthrough infections among the fully vaccinated in South Korea, the Korea Disease Control and Prevention Agency (KDCA) said in a regular briefing on Tuesday.
The KDCA said 779 out of 5,543,933 vaccinated people in Korea, or 14.1 per 100,000, are estimated to have had breakthrough infections as of Thursday.
By type of vaccine, 16.9 per 100,000 people given the AstraZeneca vaccine had breakthrough infections, 5 per 100,000 with the Pfizer vaccine, 38.5 per 100,000 with the Janssen vaccine, and 0.7 per 100,000 with cross vaccination with the first dose of the AZ vaccine and the second dose of the Pfizer vaccine.
Scientists researching the Provincetown, Cape Cod Covid outbreak reported that 79 percent of the breakthrough infections were symptomatic. Four of five people who were hospitalized were fully vaccinated.
The CDC study “raises the very worrisome possibility that high viral loads can occur in people who have Delta, and this is a fundamental as we have to approach the fall and winter,” said David O’Connor, a professor of pathology and laboratory medicine at the University of Wisconsin School of Medicine and Public Health.
As of Thursday, 882 people were tied to the Provincetown outbreak. Among those living in Massachusetts, 74% of them were fully immunized, yet officials said the vast majority were also reporting symptoms. Seven people were reported hospitalized.
At least 153 patients in Israel’s hospitals are in serious condition, of whom 28 are ventilated. 93 out of the 153 severely ill patients have been fully vaccinated, or 60% of the total.
According to the Israeli Health Ministry, 102 of the severely ill patients are aged 65 and over, 76 of whom are fully vaccinated. At least 39 of the severely ill are between the age of 40 and 65, while 16 of them are fully vaccinated. Six of the severely ill are below the age of 40 but only one of them is fully vaccinated.
In Kanta-Häme hospital epidemic, about 80% of those infected with corona have received at least the first dose of vaccine. The [Delta] variant of the coronavirus has been revealed to be the cause of the hospital epidemic. “The [B.1.617.2 Delta variant] is very easily spread.” says Chief Physician of the Kanta-Häme Hospital District Sally Leskinen. According to Leskinen, it is worrying that the precautions that have stopped the spread of previous virus variants in hospitals have not been effective enough now. “The fact that the surgical mask has been used in all situations and that patients with symptoms of infection have extensive protective equipment is not enough now,” says Leskinen.
The coronavirus epidemic has spread from Hämeenlinna to Kanta-Häme Central Hospital to health center hospitals in Hämeenlinna, Riihimäki and Forssa. There are a total of 80 infected in the chains. Hämeenlinna Central Hospital has two infection chains with a total of more than 50 infections. In addition, Riihimäki Hospital has a chain of 30 infections.
“The virus is easily infected. In those wards where infections occurred before the first cases occurred and the chains of infection were curtailed, 40 percent of patients have become infected,” says Sally Leskinen. Now the spread has been stopped and no new surprising infections have been detected in hospitals. Family members of nursing staff have also become infected, which in turn has caused extensive exposure situations in schools.
The majority of nursing staff have already received two coronary vaccinations, but still in Kanta-Häme, 11 per cent of the staff of the hospital epidemic outpatient department have been infected. About half of the infected nursing staff have had symptoms, some of them more severe.

** UPDATE 3rd August 2021 ** Eurosurveillance report:
“Exposure to SARS-CoV-2 occurred in almost every unit of the central hospital. Some exposed patients had been transferred to four of the six primary care facilities. In three of these four facilities, the outbreak spread through transfers that took place before the outbreak was detected. In the fourth facility, the transfer happened after outbreak detection and the exposed patient was quarantined and there was no further spread.”
A total of 78 Covid-19 cases in the current outbreak in Singapore have been vaccinated – many of whom are frontline workers – compared to about 300 unvaccinated cases, said Health Minister Ong Ye Kung. The numbers represent a ratio of about 79 per cent unvaccinated cases versus 21 per cent vaccinated ones. It’s “not quite” true that the situation in Singapore is “getting very bad”, he said.
Singapore is currently battling a fresh wave of B.1.617.2 infections introduced through Changi airport despite strict anti-covid protocols including regular antigen and RT-PCR testing for the workforce. About one quarter of the population of Singapore have been fully vaccinated and over one third have been partially vaccinated. Singapore has only approved the use of the Pfizer and Moderna Covid-19 vaccines for use in the country. It’s a stark warning about the difficulty of controlling the spread of the new variant first discovered in India.
