FDA clears Pfizer’s pneumococcal vaccine for infants and children

Delilah AlvaradoAssociate Editor A general view of the Pfizer Headquarters sign on November 10, 2020 in Tadworth, England. Dan Kitwood via Getty Images Dive Brief: Pfizer on Thursday gained U.S. approval of its newest pneumococcal conjugate vaccine for use in children and infants, helping it compete with a rival shot from Merck & Co. that won a similar OK last year. Pfizer’s vaccine, called Prevnar 20, is designed to protect against infection by 20 strains of the bacteria — seven more than the company’s prior Prevnar 13 version. It has been approved in adults since 2021. Last July, Merck won approval in children of its Vaxneuvance vaccine, which protects against 15 strains. Both companies could soon face more competition as the market has sparked interest from other drugmakers. Dive Insight: While vaccines for the bacterial infection are widely available, thousands of cases still lead to hospitalization and death in the ...

Exploring Doggybone ™ DNA Technology

By Michael Greenwood, M.Sc.Reviewed by Danielle Ellis, B.Sc. Doggybone DNA ™ (dbDNA) is a technology developed by biotech company Touchlight, which is a form of linear plasmid with applications in genetic engineering and therapeutics. Plasmids are small circular double-stranded DNA molecules naturally generated by bacterial cells, some eukaryotes, and archaea and separate from chromosomal DNA. Plasmids can self-replicate by using host enzymes, and each carries at least one gene, most of which are beneficial to the host. The gene(s) carried by the plasmid may then be incorporated into the genome for expression. For example, a plasmid may encode a gene that produces a protein with antiphage functionality, allowing viral resistance to be incorporated into the bacterial chromosome. Plasmids are transferred between bacterial cells via pili; thus, beneficial genes carried by plasmids can be disseminated and incorporated into the chromosomal DNA of neighboring cells. Owing to the natural function of plasmids, they can be ...

UK monkeypox vaccine rollout to wind down

The UK Health Security Agency (UKHSA) has announced its vaccination programme against mpox will end this summer. Cases of the disease have fallen from a peak of 350 per week in July to just six new cases so far in 2023, three of which were caught overseas. First doses of the vaccine will remain available to those at highest risk until 16 June, with second doses available until the end of July. The UKHSA says it will monitor cases and restart the programme if needed. While the mpox, formerly known as monkeypox, virus can infect anyone, most UK cases were among men who have sex with men. Anyone eligible who has not yet received a vaccine is being encouraged to book an appointment to protect themselves before summer. Greg Owen, from sexual health and Human Immunodeficiency Virus (HIV) charity the Terrence Higgins Trust, said: ...

Pfizer, BioNTech enlist Marvel’s Avengers in latest COVID-19 vaccine booster push

Just like how the Avengers have repeatedly kept the world safe from Ultron, people need to protect themselves by updating their COVID-19 vaccination with the latest booster. That’s the message Pfizer and BioNTech are trying to get across in a new custom comic book partnered with Marvel. The companies unveiled the project Tuesday. “We are proud to work with Marvel, which is so firmly entrenched in global culture and entertainment, to help remind people of the actions they can each take to help protect themselves, similarly to how the Avengers protect their community,” Pfizer said in a statement shared with Fierce Pharma Marketing. The new comic, titled “Everyday Heroes,” represents Pfizer flexing its marketing muscle. COVID vaccines are slated to switch to the private commercial market after the U.S. government failed to secure additional funding from Congress. As Pfizer CEO Albert Bourla, Ph.D., has said, Pfizer can be “even more competitive” and ...

Adding new vaccine type to leading immunotherapy dramatically reduced melanoma recurrence

The combination of an experimental mRNA vaccine with an immunotherapy reduced the likelihood of melanoma recurring or causing death by 44% when compared to immunotherapy alone, a new clinical trial shows. Led by researchers at NYU Langone Health and its Perlmutter Cancer Center, the randomized phase 2b trial involved men and women who had surgery to remove melanoma from lymph nodes or other organs and were at high risk of the disease returning in sites distant from the original cancer. Among 107 study subjects who were injected with both the experimental vaccine, called mRNA-4157/V940, and the immunotherapy pembrolizumab, the cancer returned in 24 subjects (22.4%) within two years of follow-up, compared with 20 out of 50 (40%) who received only pembrolizumab. “Our phase 2b study shows that a neoantigen mRNA vaccine, when used in combination with pembrolizumab, resulted in prolonged time without recurrence or death compared with pembrolizumab alone,” said study senior investigator ...

Moderna cancer vaccine takes positive step

Company’s candidate, in combination with MSD’s Keytruda, receives PRIME designation Moderna has announced that mRNA-4157/V940 – its investigational cancer vaccine – in combination with Keytruda, Merck’s anti-PD-1 therapy, has been granted Priority Medicines (PRIME) scheme designation by the European Medicines Agency (EMA). It concerns the adjuvant treatment of patients with high-risk stage III/IV melanoma following complete resection. The vaccine mRNA-4157/V940 stimulates an immune response by generating specific T cell responses based on the unique mutational signature of a patient’s tumour. The EMA awarded the PRIME scheme designation following positive data emerging from the phase 2b KEYNOTE-942/mRNA-4157-P201 clinical trial. The results from this research will be shared at the American Association for Cancer Research (AACR) in mid-April. PRIME is a regulatory system run by the EMA that provides support for the development of medicines that target unmet medical needs. Through PRIME, the EMA offers proactive and early ...

Pfizer and Moderna’s COVID-19 vaccines offer lasting protection

Study finds on April 7th, 2023, Pharmaceutical Technology reported that a new study has found that Pfizer and Moderna’s COVID-19 vaccines offer lasting protection against the virus. The study, which was published in the New England Journal of Medicine, found that people who received either vaccine had robust and persistent antibody and T cell responses against SARS-CoV-2, the virus that causes COVID-19, even six months after receiving the second dose. The study followed 2,500 healthcare workers who received either the Pfizer or Moderna vaccine and found that their immune responses remained strong over time. The researchers noted that while antibody levels did decline over time, the levels were still high enough to provide protection against the virus. The findings are significant because they suggest that the vaccines are likely to provide long-term protection against COVID-19. The study also provides reassurance that the vaccines are effective against new variants of ...

Immunomodulators boost vaccine response and reduce inflammation, finds study

Adjuvants—ingredients that help boost the immune response in vaccines—have been used in vaccines for decades. But inducing a stronger immune response can result in more unwanted side effects, like swelling at the injection site or fever and body aches. Researchers at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have found that adding small molecules called immunomodulators to vaccine adjuvants gives them the ability to better regulate the body’s response to vaccines. “If you think of adjuvants as a megaphone that stimulates the immune system, then you can think of immunomodulators as a sound mixer,” said Jeremiah Kim, a graduate student and co-lead author of the paper. “We’re able to selectively tune the immune response to reduce negative side effects.” In models, adding immunomodulators to a flu vaccine increased antibody response, and adding them to a typhoid vaccine reduced inflammation. The results were published in ACS Central Science. Graduate student Matthew Rosenberger was also a ...

mRNA vaccine beats infection for key defense against COVID-19, Stanford Medicine scientists find

Stanford Medicine researchers have shown that prior SARS-CoV-2 infection reduces killer T cells’ response to vaccination. These cells are crucial for eliminating the virus from the body. March 28, 2023 – By Bruce Goldman T cells are more difficult to measure than antibodies, but they play a crucial role in fighting pathogens.Kateryna Kon/Shutterstock.com The Pfizer/BioNTech mRNA vaccine directed at COVID-19 is much better than natural infection at revving up key immune cells called killer T cells to fight future infection by SARS-CoV-2, the virus that causes COVID-19, Stanford Medicine investigators have found. The scientists also showed, in a study published online in Immunity, that getting infected by SARS-CoV-2 before getting vaccinated lowers the vaccine’s otherwise exceptional ability to spur proliferation and activation of killer T cells directed at SARS-CoV-2. Their finding suggests that those hoping to avoid the manifold health risks associated with COVID-19 would do well to get vaccinated before they contract ...
