British pharmaceutical company, AstraZeneca, announced that the COVID-19 vaccine it is developing with Oxford University is 90% effective and also prevented 70% of trialists from falling ill.

This was disclosed by AstraZeneca on Monday and reported by Reuters and Bloomberg. AstraZeneca said its vaccine was 90% effective when a half dose was issued, followed by a full dose 30 days later.

AstraZeneca joins other major pharmaceutical companies including Pfizer and Moderna in the race to develop a vaccine for the pandemic.

What they are saying

Oxford University said it could be 70.4% effective and tests on two dose regimes show that it could be is 90%.

Interim data shows the #OxfordVaccine is 70.4% effective and tests on two-dose regimens show that it could be 90%, moving us one step closer to supplying it at low cost around the world,” they announced on social media. Monday’s announcement came after trial data was released in the UK and Brazil.
“We see a lot of merit in this regimen and we will now start discussions with regulators into incorporating this dose combination for further clinical investigation,” an Astra spokesman told Bloomberg.
Chief Executive, Pascal Soriot, said: “This vaccine’s efficacy and safety confirm that it will be highly effective against COVID-19 and will have an immediate impact on this public health emergency.

The company expects to have up to 200 million doses by the end of the year and produce up to 700 million doses by the first quarter of 2021.

The new vaccine also answers issues of vaccine storage and distribution, as it can be kept at basic refrigerator temperature for transport, making it much easier to transport, compared to Moderna and Pfizer’s vaccines.

What you should know 

Nairametrics reported earlier this month that Pfizer Inc disclosed that its experimental vaccine, which is jointly developed with BioNTech was more than 90% effective in preventing COVID-19, based on initial data from a large study, in the ongoing phase 3 trials.

Last week, Pharmaceutical company, Moderna Inc, stated its COVID-19 vaccine is 94.5% effective in treating coronavirus, after preliminary analysis of a large late-stage clinical trial.

COVID-19: Evidence suggests that new variants could pose challenge for vaccines

The research findings show that the new COVID variants may likely not respond well to the vaccines.

Published

on

Recent research findings suggest that the new coronavirus variants would likely pose a big challenge for the vaccines, as revealed by studies by several medical researchers.

The new variant was first discovered in South Africa in October but has now been spread to more than a dozen countries all over the world.

According to the most recent findings, as reported by CNN, researchers took antibodies from six people who were hospitalized with Covid-19 before the new variant was discovered. They found to varying degrees, that the antibodies for all six of the survivors were unable to fully fight off the virus.

According to Alex Sigal, a virologist at the Africa Health Research Institute and the Max Planck Institute for Infection Biology, “I think the evidence is building that these mutations — and I think other mutations — will emerge across the globe — and are emerging already — that are escaping antibodies from previous infection. It’s concerning.”

According to Jesse Bloom, a virologist at the Fred Hutchinson Cancer Research Center, “When you see two groups independently arriving at same basic answer, that good — there’s more consonance that they are correct”

What you should know

  • Sigal’s findings were very similar to those of a recent study by the National Institute for Communicable Diseases in South Africa.
  • A research study has revealed that mutations in the new variant allowed them to evade some of the immunity induced by vaccination, but it was far from a complete escape.
  • One thing that is critically safe for everyone is to get vaccinated, while the researchers are working to confirm whether these variants are dangerous or not to contain with the vaccines.
  • According to Alex Sigal, “I would for sure get it if I could. My father-in-law had the opportunity to fly to Israel and get it, and I was shooing him out of the house because you can’t get it here in South Africa.”
  • In a research study done at Rockefeller University, from a sample of 20 people who had received either the Moderna or the Pfizer vaccine, it was found that different mutations in the viruses did allow some escape from some types of antibodies, but the volunteers’ immune systems threw an army of different types of antibodies at the viruses.
  • According to the research conducted in South Africa, blood was drawn from 44 people who had Covid-19 but the antibodies of about half of the 44 people were powerless against the new variant, while the other half, their antibody responses were weakened, but not totally knocked out.
