The Pfizer/BioNTech vaccine appears to work against an important mutation in the new coronavirus variants causing havoc in the UK and South Africa, according to research from the drugs giant. The study team tested blood taken from people who had received the mRNA vaccine developed by BioNTech and Pfizer.
million people have been infected and over 165,000 have died, the promise of a vaccine is hampered by a vexing epidemic that long preceded Covid-19: obesity. The finding was replicated in a follow-up study that used longer needles to ensure the vaccine was injected into muscle and not fat. In the United States, where at least 4.6
Moderna has joined forces with non-profit organisation IAVI on a third phase 1 trial of its candidate HIV vaccine in Africa, where the burden of the virus is still being keenly felt. There are hopes that its mRNA approach, which proved so effective against COVID-19, could succeed where traditional vaccine technologies have failed in HIV.
QUICK THOUGHT: People believe the COVID-19 vaccine was developed in less than a year but that’s not true. Based on the virus a number of vaccines targeting the spike protein were designed, tested in animal models and found to be quite promising against SARS and other coronavirus illnesses like Middle East respiratory syndrome.
J&J has announced early trial results that suggest its single-shot coronavirus vaccine provides a sustained response against the virus ahead of a phase 3 trial readout due later this month. Both of these vaccines require two doses, as does the most recently approved shot from Moderna, which is due to arrive in the UK in the spring.
Pfizer/BioNTech’s mRNA vaccine against COVID is a technical marvel – but the ultra-cool temperatures required for storage and stability has been tricky to handle. A nasal delivery method will also produce an immuneresponse at the point where the virus enters the body.

Scientists have discovered there is a "Goldilocks" effect in identifying the size of a "vaccine adjuvant" that can trigger strong immuneresponses and, as an example, have shown that a safe, biodegradable adjuvant can boost the action of cancer-killing cells—if the particles are the correct size.
Just a few months after starting clinical trials of its nasal spray vaccine for COVID-19, US biotech Altimmune is abandoning the project, saying that it generated weaker than expected immuneresponses in a phase 1 trial. .
Phase 2 trials in 1,200 adults, young children, and infants suggest new poliovirus vaccine may have the potential to overcome outbreaks caused by a mutated polio strain linked to the oral vaccine that typically circulates in areas of low immunisation coverage, and poses one of biggest barriers to eradication.
The US Food and Drug Administration (FDA) has green-lighted the first pneumonia vaccine specifically designed for adults 50 years of age and older. These numbers do not reflect the efficacies of the vaccines, which have not been compared head-to-head in any trial yet.
The first peer-reviewed study in North America examining the timing between the first and second doses of COVID-19 mRNA vaccines shows that a longer dose interval leads to a stronger immuneresponse. The study is funded by the Government of Canada through its COVID-19 Immunity Task Force (CITF).
In 2021, a group of scientists led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine and NewYork-Presbyterian reported that the Moderna mRNA vaccine and a protein-based vaccine candidate containing an adjuvant, a substance that enhances immuneresponses, elicited durable neutralizing antibody responses to SARS-CoV-2 (..)
The developer of Russia’s COVID-19 vaccine Sputnik V has pledged to make it available for less than $10 per dose – or $20 per two-dose course – on the same day as revealing new clinical data with the shot. Pfizer and Moderna’s vaccines require much lower temperatures to prevent their active ingredients from breaking down.
Scientists in the US say they have developed an mRNA-based vaccine that encompasses all 20 known subtypes of influenza that could form the basis of a future universal jab. The goals of the programme are also similar to those in COVID vaccine development.
Giving one dose each of AstraZeneca and Pfizer COVID-19 vaccines provides good protection against the SARS-CoV-2 virus, but may be associated with more adverse reactions, according to new clinical trial data. Third AZ dose generates strong variant response.
The findings provide direction for future vaccines or therapies that may offer broader protection against variants LA JOLLA, CA–Fast-spreading variants of the COVID-19-causing coronavirus, SARS-CoV-2, carry mutations that enable the virus to escape some of the immuneresponse created naturally or by vaccination.
The study assessed cynomolgus macaques vaccinated with 12µg of either the first or second-generation vaccine candidate. During challenge with the original SARS-CoV-2 virus, animals vaccinated with CV2CoV were found to be better protected based on highly effective clearance of the virus in the lungs and nasal passages.
… Moderna disclosed that its Covid-19 vaccine booster targeting the BA.1 1 subvariant of Omicron generated a strong immuneresponse against that variant, with antibody levels staying high for at least three months , Reuters notes. Omicron-tailored 5 targeted vaccine later this year. 5 subvariants of Omicron.
7, 2020 — Scientists say they may be getting closer to creating a universal flu vaccine. In an early-stage clinical trial with 65 volunteers in the United States, an experimental vaccine triggered strong immuneresponses to a wide range of flu virus strains and subtypes. MONDAY, Dec.
AstraZeneca and Johnson & Johnson are both exploring ways to modify their COVID-19 vaccines to minimise the risk of severe blood clotting reactions that are seen – albeit rarely – in some people receiving the jabs. Its guideline is due to be published before the end of this month.
In a press briefing on Monday, the World Health Organization (WHO) responded to questions about COVID-19 vaccine boosters that led to a flurry of misleading headlines in the media about the “dangers” of mixing and matching vaccines.

officials ramped up efforts to vaccinate more Americans, scientists around the world wrestled with whether it would make sense to delay the second doses everyone will need so more people can be vaccinated more quickly. Each vaccine would still be delivered in two doses given four weeks apart. MONDAY, Jan.
A new effort is under way to understand how the immune system responds to coronavirus. Scientists from 17 UK research centres are attempting to answer questions such as how long immunity lasts and why disease severity varies so much. The immune system is underlying everything that’s key to the response to this virus.”.
Moderna has been testing an experimental mRNA vaccine aimed at combating the human cytomegalovirus (CMV), which poses significant health risks to newborns and immunocompromised patients. The team used the data and patient samples from a gB/MF59 Phase II trial in adolescent girls as a benchmark to assess the new mRNA-based vaccine.
A study has found evidence that protection from the AstraZeneca and Pfizer/BioNTech COVID-19 vaccines starts fall off after a few months, but a UK government advisor says there’s no need to rush into a large-scale booster campaign.
A malaria vaccine developed by members of the University of Oxford team behind the AstraZeneca COVID-19 jab has been hailed as a possible game-changer in the fight against the deadly parasitic infection. g) dose of Novavax’ Matrix-M adjuvant, used to boost the immuneresponse to the R21 antigen. g) or high (50 ?g)
Sanofi and GlaxoSmithKline have said their COVID-19 vaccine has hit a snag in clinical development, prompting analysts to note this could delay delivery of potentially more than a billion shots globally by up to nine months. AZ to combine vaccine with Russian rival.
The UK has formed an partnership with German biotech BioNTech to provide up to 10,000 patients with access to personalised cancer therapies, in another example of the country embracing the mRNA technologies that underpinned COVID-19 vaccines. It will also cover some infectious disease targets.
It also seems to be very adept at evading the immuneresponse owing to a plethora of mutations that makes it immune evasive. “It The new subvariant has also been dubbed “Kraken” by some scientists. on the horizon as scientists say the virus appears to be rapidly evolving , mutating faster than most viruses.
The far more boring truth is that scientists are not magicians or prophets and estimations cannot always be precise. For Covid-19 the herd immunity threshold is 70% but this is only a rough estimate based on the current numbers we’re seeing. . Thus, herd immunity wouldn’t work in this scenario.
For their remarkable scientific contributions, doctoral student Julia Klaus, Zurich University VetSuisse Faculty, and Dr Yasmin Parr from the MRC-University of Glasgow, Centre for Virus Research, have received the 2021 ABCD Young Scientist Award. To foster young talent development in the feline health research community. References.
