Vaccinia Virus News and Research

RSS

The vaccinia virus is the "live virus" used in the smallpox vaccine. It is a "pox"-type virus related to smallpox. When given to humans as a vaccine, it helps the body to develop immunity to smallpox. The smallpox vaccine does not contain the smallpox virus and it cannot cause smallpox.

Vaccination against smallpox efficiently protects against monkeypox infection

In a new study, researchers assessed the existing information regarding monkeypox infections.

Animal study suggests intranasal COVID vaccine delivery more efficient than intramuscular

In a recent study published in the journal PNAS, researchers demonstrated higher comparative efficacy of the intranasal (IN) route of coronavirus disease 2019 (COVID-19) vaccine administration versus intramuscular route in mice.

Efficacy of MVA-CoV2-S vaccination to prevent SARS-CoV-2 cerebral infection and associated damage

Researchers demonstrated that an MVA vector expressing the SARS-CoV-2 spike protein was 100% effective in preventing neuroinvasion and brain damage by SARS-CoV-2 in transgenic mice.

Oral bacteria-based SARS-CoV-2 vaccine platform

In a new study, researchers engineered the bacterial strain, Salmonella, to express differently-sized antigens to serve as vaccine platforms.

New vaccinia-based COVID-19 vaccine candidate induces robust, durable immune responses

Researchers in Australia have developed a coronavirus disease 2019 (COVID-9) vaccine that induced robust and long-lived humoral and cellular immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in both young and aging mice.

Vaccinia-based COVID-19 vaccines confer immunity in hamster model

In a paper recently uploaded to the preprint server bioRxiv* by Kulkarni et al. (August 3, 2021), the potential of vaccinia virus-based vaccines expressing the full-length SARS-CoV-2 spike protein is examined in mice and Syrian hamsters. The findings report that the vaccine generates high titers of neutralizing antibodies with good activity towards SARS-CoV-2 variants of concern.

CDC monitoring over 200 individuals possibly exposed to monkeypox

The United States Centers for Disease Control and Prevention (CDC) is monitoring over 200 people who may have been exposed to the monkeypox virus.

Researchers review environmental risk assessments for recombinant COVID-19 viral vector vaccines

In a recent review, published in the journal Vaccines, researchers in Belgium look at the recombinant viral vector-vaccine candidates that are primarily against SARS-CoV-2 still in development and discuss their features from an environmental risk point of view.

Vaccines delivered via skin may offer better protection against respiratory diseases

Among infectious diseases that have caused pandemics and epidemics, smallpox stands out as a success story. Smallpox vaccination led to the disease's eradication in the twentieth century.

MVA SARS-CoV-2 vaccine candidate shows strong immunogenicity in preclinical trials

A new study reports the preclinical testing of a recombinant MVA (rMVA) candidate vaccine against SARS-CoV-2, the agent that is causing the current COVID-19 pandemic.

Modified Vaccinia Ankara model vaccine prevents COVID-19 in transgenic mice study

A new study shows the effectiveness of a novel recombinant vaccinia virus that expresses modified SARS-CoV-2 spike antigen, in preventing the replication of the virus in the respiratory tract of transgenic mice, and to prevent lethal disease.

Disinfectants with "virucidal activity against enveloped viruses" effective against SARS-CoV-2

A recent study demonstrated that two commercially available surface disinfectant formulations and one hand disinfection formulation that claim "virucidal activity against enveloped viruses" are effective in inactivating the SARS-CoV-2 virus. Their study has been published on the preprint server bioRxiv.

Green tea and some fruit juices inhibit SARS-CoV-2 in vitro

Green tea, chokeberry juice, and pomegranate juice killed flu and SARS-CoV-2 viruses when incubated with the viruses in vitro. Thus, oral rinsing using these might be effective in preventing COVID-19.

5 Nov 2020

Modified Vaccinia Ankara-based vaccine candidate for SARS-CoV-2

Now, a new study by researchers at Emory University, the University of Texas Medical Branch and the Ragon Institute and published on the preprint server bioRxiv in June 2020 reports the development of a promising new vaccine candidate that may rapidly and effectively induce the production of neutralizing antibodies against the spike protein of the virus.

Scientists solve 3D structure of vaccinia virus RNA polymerase

For viruses to multiply, they usually need the support of the cells they infect. In many cases, only in their host's nucleus can they find the machines, enzymes and building blocks with which they can multiply their genetic material before infecting other cells.

Cells form cage-like structures that trap viruses, find scientists

Scientists have shown that cells can form cage-like structures around viruses to trap them and prevent them from spreading to nearby cells.
