Only a few weeks into the new year, the prospect of getting a successful advanced HIV vaccine shrank after the discontinuation of yet another late-stage trial. On January 18, Janssen, a Johnson & Johnson (J&J) subsidiary, stated that its vaccine was not effective in preventing HIV infections.
Intranasal delivery of ChAdOx1 nCoV-19 failed to induce either a consistent mucosal antibodyresponse or a strong systemic immuneresponse, according to results from a Phase 1 clinical trial released today.
The UK Medicines and Healthcare products Regulatory Agency (MHRA) has granted conditional authorisation for Moderna ’s Covid-19 booster vaccine, mRNA-1273.214 (Spikevax Bivalent Original/Omicron), for use in adults aged 18 years and above. It comprises mRNA-1273 (Spikevax) and a vaccine candidate that acts on the SARS-CoV-2 virus’ BA.1
A trial of Russia’s Sputnik V coronavirus vaccine has shown the jab produces an immuneresponse, although the study was too small to produce conclusive findings, particularly on safety. The vaccine also produced a T-cell response within 28 days, a secondary outcome.
It will also be used for the treatment of people who are not likely to have an adequate immuneresponse to Covid-19 vaccination or for people who are not recommended for Covid-19 vaccination. Evusheld (formerly AZD7442) is a combination of two long-acting antibodies, tixagevimab (AZD8895) and cilgavimab (AZD1061).
The European Medicines Agency (EMA) has recommended HIPRA’s Covid-19 vaccine , Bimervax, as a Covid-19 booster. Available to people ages 16 years and above who have been vaccinated with a Covid-19 mRNA vaccine, EMA’s Human Medicines Committee concluded the vaccine is ready for marketing authorization in the EU, on 30 March.

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.
Nearly three years into the pandemic, many of us now carry antibodies against the virus—due to an infection or two, a few doses of mRNA vaccine, or a round of monoclonal-antibody treatment.
AstraZeneca’s antibody cocktail for COVID-19, now called Evushield, has become the first drug in the class to be authorised for prevention of infection by the US FDA. The emergency use authorisation (EUA) for Evushield activates a 700,000 order for the antibody from the US government, worth upwards of $726 million.
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.
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.
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.
MBA, managing director at CanSino Biologics Europe, tells us about Convidecia, a single dose SARS-CoV-2 vaccine offered as an injectable and inhalant that allows ease of storage, an alternative option for individuals with needle phobias, and robust elongated CD4 and CD8 cellular response. Morgon, PharmD, LL.M, How it works.
The Korean Ministry of Food and Drug Safety (KMFDS) has granted expanded approval to Novavax partner SK bioscience for the Covid-19 vaccine, Nuvaxovid (NVX-CoV2373), for use as a booster dose in adults aged 18 and above. Nuvaxovid is a protein-based vaccine created from the genetic sequence of the initial SARS-CoV-2 virus strain.
An intranasal formulation of AstraZeneca’s widely-used COVID-19 vaccine Vaxzevria has failed at the first hurdle, after results from a phase 1 trial found it was unable to stimulate a strong immuneresponse to the virus. Other efforts to develop a nasally-delivered COVID-19 vaccine have met with greater success.
Formed after exposure to a pathogen or vaccine, germinal centers act as a kind of immune system training academy, helping B cells refine their response to the threat.
Myocarditis, a condition in which the heart muscle becomes inflamed, is a rare complication that can occur after mRNA COVID vaccination. It's estimated that roughly 18 cases occur in every 1 million vaccine doses administered, making it so rare that it is challenging to find cases to investigate.
Preliminary data from an ongoing trial of AstraZeneca’s COVID-19 vaccine Vaxzevria has shown that a booster dose stimulates an increase in antibodies against Omicron, as well as other variants of the virus, including Alpha, Beta, Delta, and Gamma. billion doses administered. billion doses administered.
Moderna has said that its coronavirus vaccine stimulated an immuneresponse in older people in phase 1 trials, suggesting that the jab is effective in the age groups most susceptible to COVID-19. These antibody levels were also higher than those typically seen in people recovering from the virus, the company said.
ImmunityBio has licensed technology underpinning a COVID-19 vaccine that could be administered orally rather than by injection from UK biotech iosBio. Non-injectables remove the need for health professional-led immunisation programmes, making widespread vaccine roll-outs quicker and easier and more affordable,” Channon told pharmaphorum.
A peptide vaccine developed by Australia’s Imugene has reduced tumour size in around half of patients with HER2-positive gastric or gastroesophageal junction (GEJ) cancer in a phase 2 trial. The post Imugene HER2 vaccine hits target in stomach cancer trial appeared first on.
AstraZeneca has sought emergency use authorisation for its antibody combination AZD7442, following trial results indicating it can prevent symptomatic COVID-19 infection when given to healthy patients. The post AZ files for emergency use of COVID-19 antibody combo in US appeared first on. Initial results from that study were negative.
Evaxion Biotech and ExpreS 2 ion Biotechnologies have entered a vaccine discovery collaboration agreement to co-develop a new cytomegalovirus (CMV) vaccine candidate. CMV represents a critical unmet medical need, and I believe our two companies have the potential to deliver a truly differentiated vaccine.”.
A single dose of the COVID-19 monoclonal antibody therapy developing Regeneron reduced the risk of contracting the virus by around 82% for up to eight months, according to new trial data. The rate of COVID-19 vaccination was balanced between the two groups. The rate of COVID-19 vaccination was balanced between the two groups.

Moderna revealed the first interim results from a small, Phase I study of its mRNA-based influenza vaccine, which showed that the vaccine had no significant safety concerns and elicited immuneresponses against four strains of the influenza virus. Antibody levels against the A strains were higher than the B subtypes.
Gritstone bio has reported interim results from an ongoing Phase 1 study evaluating the company’s self-amplifying mRNA (samRNA) vaccine as a boost against Covid-19 (CORAL-BOOST).
