In Scotland, COVID shots spark big drop in hospitalizations

  • Jane Malysiak has received the first COVID vaccine in Australia

In the USA, the Mayo Clinic had similar findings with both the Pfizer and Moderna vaccines.

The number of coronavirus cases has been falling for a while now across the United Kingdom, along with the number of people in hospital and deaths linked to the disease. As such, the government must ensure everybody in the country is able to receive Covid-9 vaccine promptly.

Scientists are now tentatively beginning to conclude that we can see the effect of the vaccines in the figures.

This pre-print (not peer-reviewed) paper from the University of Edinburgh analysed data from 5.4 million people - nearly the entire population of Scotland. But if a vaccine is largely preventing people from being sick and from carrying enough of the virus to test positive, that means it's also lowering the risk of virus transmission from a vaccinated person to others.

The study, in which the University of Strathclyde is a partner, is the first to describe across an entire country the effect of the Pfizer and Oxford-AstraZeneca jabs in the community on preventing severe illness resulting in hospitalisation.

The vast majority of the population will be injected with the AstraZeneca vaccine, which can be produced locally, by the end of October.

For people over 80, one of the groups most at risk, the average risk reduction from the results of both vaccines was 81 percent.

But for the Pfizer vaccine studies, that had involved a second dose being given after three weeks.

Ireland needs to rethink its Covid-19 immunisation strategy given new findings in relation to the Pfizer BioNtech vaccine which would allow more people get their first dose sooner, according to an immunologist at University College Cork.

Stephen Wade, SA's health minister, said he expected "road bumps" in the rollout but was confident in SA's "nimble, evidence-based approach". At each stage, the government says its decisions will be driven by data - figures on the vaccine rollout program, hospital admissions and deaths, infection rates, and impact of any new variants.

Late previous year, a number of vaccines were developed by a few countries and emergency authorisations were given by many governments for their use on their citizens.

"Reducing the people with infection, both symptomatic and asymptomatic, is the biggest thing that will reduce transmission", said Susan Hopkins, strategic response director to Public Health England.

About 80% of SARS-CoV-2 cases in Israel during the time period of the study, from January 17 to February 6, were caused by the more transmissible strain first identified in the U.K. Israel's vaccination drive began just before the so-called B.1.1.7 variant emerged, fueling infections and leading to a third lockdown on January 8.

The PHE study also showed high levels of protection against the so-called United Kingdom variant.

All that said, this is undoubtedly good news if you're hoping for an end to the pandemic as swiftly as possible. The first population-level studies have been reported from Israel.

Following Prime Minister Scott Morrison on Sunday, other political leaders received their vaccinations today in Canberra.

The PHE data come as preliminary study findings from Scotland on Monday also showed the vaccination drive there is working, markedly reducing the risk of hospitalisation for Covid-19.
