The preliminary results of a study of nearly all the inhabitants of Scotland suggest that PFIZER/BionTech and AstraZeneca coronavaccins work well to prevent serious signs of disease.
The research team reports that vaccinated 80s are 81 percent less likely to have corona-related hospitalization. That percentage applies from four weeks after the first injection and is the average of the two vaccines that are pricked in Scotland.
Exactly what we hoped for.
The preliminary results – the research has not yet been reviewed by peers – give researchers hope that vaccination will make an important contribution to controlling the pandemic.
Epidemiologist Frits Rosendaal (LUMC) is not involved in the study, but shares optimism. “These results are exactly what we hoped for. It means that vaccination provides both enormous relief for hospitals and relief of serious illness by covid-19. This shows that vaccination is really the way out of this crisis.”
Great Britain Roadmap
The research results come on the day British Prime Minister Johnson announces easing. He presents a roadmap for the reopening of the country after more than one and a half months of strict lockdown. The reason for this is the sharply reduced levels of infection and the significantly increased vaccination rate.
More than a quarter of all British people have had at least one shot. Everyone over 70 years of age has been offered a vaccination. Only in countries such as Israel and the United Arab Emirates have relatively more inhabitants vaccinated against the virus. By comparison, in the Netherlands, 4.5 percent of the population received a first shot.
The Scottish researchers write that they have now done the first national study on the effect of the two vaccines on the number of hospitalizations due to covid-19. “For the whole Scottish population, the results show a substantial effect after a single shot,” says the chief researcher and director of the Ushers Institute of the University of Edinburgh, Aziz Sheikh.
For the study, researchers analyzed the dataset for 5.4 million inhabitants of Scotland. The data were collected between 8 December and 15 February. At that time, 1.14 million doses were administered. More than one in five Scots has received a first shot.
Last weekend, the Financial Times noticed a vaccination effect in the UK. According to the newspaper, this effect can be seen in the hospitals and the number of coronadodes. These numbers are falling across the board of the population, but the largest decrease is visible among people over 80 years of age.
According to the newspaper, the effect appears to be a lot less significant on the number of detected infections. “Inoculation seems to be more successful in limiting the number of cases in which people become seriously ill than stopping the spread of symptomatic infections,” concludes the author.
Do not softer too quickly
Epidemiologist Rosendaal hopes that Prime Minister Johnson will remain reluctant to ease. Despite the positive vaccination news, the situation is still too fragile for a quick end to the lockdown. Especially since inoculation seems to have little impact on the spread of the virus.
“ The average age of coronapatics in the ICs is about 64 years in the Netherlands. This means that about half of the people are younger and they have not yet been vaccinated, both in the Netherlands and in the United Kingdom. So you dont want the younger people to get sick and yet again raise the pressure on care.”
