Presentational white space

Next week will see the most significant lifting of restrictions yet in England, with indoor mixing to be allowed. The rest of the UK is making similar steps, reports BBC.

The vaccines are working wonderfully

It means the onus is increasingly shifting on to the vaccines, rather than social distancing and restrictions, to keep the virus at bay. How well do they work? And is there now enough immunity in the population to protect us all?

The UK has benefited from both fast rollout and good uptake....

The Efficiency of COVID-19 Vaccines On Variants Is Uncertain

New variants of concern have changed the game, spreading worldwide and threatening to derail pandemic control efforts, reports The Guardian.

Increase in variants 

At the end of 2020, there was a strong hope that high levels of vaccination would see humanity finally gain the upper hand over Sars-CoV-2, the virus that causes Covid-19. In an ideal scenario, the virus would then be contained at very low levels without further societal disruption or significant numbers of deaths.

But since then, new...

Real World CDC Study Shows COVID Vaccines Effective After First Dose

According to a Reuters report, a new real-world study in the US has revealed that COVID-19 vaccines developed by Pfizer Inc with BioNTech SE and Moderna Inc reduced the risk of infection by 80% two weeks or more after the first of two shots. 

The risk of infection fell 90% by two weeks after the second shot, the study of nearly 4,000 U.S. healthcare personnel and first responders found.

 Previous Study Results Validated

The results validate earlier studies that had indicated the vaccines begin to...

COVID Shots Halted Due To Defective Vials Amid Vaccination ‘Hiccup’

  • More than 50 defects in BioNTech vaccine packaging reported by frontline staff, including cracks, leaks and stains on outside of glass vials; all problematic vaccines disposed off.
  • Defects reported to distribution agent Fosun, which told local government to suspend jabs on Wednesday morning as precautionary measure.
  • About 150,000 doses of batch 210102 administered as of Wednesday; doses from another batch, 210104, not yet used.
  • Health officials stress no safety risks arising from packaging...

COVID Vaccines Could Be ‘Inept’ Against Variants, Says New Study

  • Pfizer’s and Moderna’s shots were at least 10 times less effective against variant in a new study.
  • Researchers tested the vaccines on a variant first found in South Africa, which is now in 20 states.
  • A mutation on the variant called E484K appeared to be a “major contributor,” the study authors said.

According to a lab study, COVID-19 vaccines from Moderna and Pfizer-BioNTech appear significantly less effective against the coronavirus variant first found in South Africa, reports Yahoo News.

Pfizer Vaccine Effective From Day 11 Post 1st Dose, Study Finds

  • New Australian research suggests that the second ‘booster’ dose of the Pfizer-BioNTech vaccine may not increase vaccine efficacy against SARS-CoV-2.
  • The results suggest one dose of the vaccine could be sufficient in providing a robust immune response 11 days after inoculation.
  • The findings could help shape policy as vaccine rollout has been slow in countries such as the United States and Canada.

A team of researchers suggests that one dose of the Pfizer-BioNTech vaccine could be sufficient in...

Countries Should in Transport & Storage Infrastructure for COVID Vaccine

The negative effects of the Covid-19 pandemic have necessitated various medical boards across the globe to begin the emergency usage of Covid-19 vaccines, bringing reprieve and optimism in 2021 but the problem of vaccine transport remains, reports the Daily Star. 

The Storage & Distribution Challenge

Pfizer-BioNtech is arguably one of the most effective Covid-19 vaccines, with a proven efficacy of 95 percent. The vaccine is, however, required to be stored between -80 degrees Celsius and -60...

COVID Vaccinations Reduce Hospitalisation Risk

  • Covid vaccinations are reducing hospitalization risk amongst people.
  • The effectiveness is substantial on the vulnerable group of those above 80
  • The reduction is seen from the 4th week of vaccination. 
  • The reduction was 85% for Pfizer and 94% for AstraZeneca covid vaccines. 

According to a Scottish Study, vaccination drive appears to be markedly reducing the risk of hospitalization for COVID-19, suggesting that both the Pfizer-BioNtech and Oxford-AstraZeneca shots are highly effective in...

From Improved Storage To New Variant Efficacy – Pfizer COVID Vaccine Shines

  • New research and lab studies are providing more hope for the Pfizer vaccine.
  • While Pfizer’s own study has shown that the vaccine can be stored in warmer temperatures now, a lab study has shown its effectiveness in new variants. 
  • Lab studies show the vaccine can neutralise  two-third of the south African Variant.
  • Pfizer has said there’s no real life report of new variants escaping the vaccine.
  • Meanwhile Pfizer provided data that shows the vaccine can be stored at -70 ° instead of -112°
  • Pfizer...
