UK: 52% vaccine breakthrough for hospitalized over-50s

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.

Finland: 80% vaccine breakthrough in hospital with B16172 Delta #coronavirus variant – PPE no longer effective – UPDATED

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. report (in Finnish)

** 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.”

Singapore: 78 #coronavirus cases in current outbreak were vaccinated compared to about 300 unvaccinated cases

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. report

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.
