Inhaled single dose vaccine creates antibodies and prevents infection in rhesus macaques

Now, a new preprint research paper describes a chimpanzee adenovirus-vectored vaccine that, when administered intranasally in rhesus macaques, led to a robust immune response and demonstrated protection against infection by the virus that causes COVID-19, namely, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The preprint is published on the bioRxiv server.

Interim results show Oxford COVID-19 vaccine protects against symptomatic disease

First full results from interim analysis confirm that the Oxford COVID-19 vaccine (AZD1222) has an acceptable safety profile and is efficacious against symptomatic COVID-19 disease, with no hospitalizations or severe disease reported in the COVID-19 vaccine group so far.

The intranasal route of immunization may offer effective protection against SARS-CoV-2

Researchers at the School of Medicine, Washington University in Saint Louis, USA, showed that the intranasal route of immunization could provide a more efficient protection against SARS-CoV-2 compared to the intramuscular route (i.e. through ‘jabs’).

Booster dose enhances immunogenicity of ChAdOx1 SARS-CoV-2 vaccine in aged mice

Now, a new study published on the pre-print server bioRxiv* shows that a single dose of the vaccine has induced cellular and humoral immunity in aged or older mice. A second dosage was needed to enhance the vaccine's immune response, showing that a prime-boost strategy may be an essential step to boost immunogenicity in the elderly.

Phase 1 trial results of gorilla adenovirus vaccine for COVID-19

A recent study published on the preprint server bioRxiv* in October 2020 reports the development of a novel vaccine based on a simian adenoviral vector obtained from a group C gorilla isolate called GRAd32. This could help speed up vaccine development.

Study indicates an ancient explanation on link between humans and long-lived primate

Many humans live to see their 70s and 80s, some even reach 100 years old. But life is much shorter for our closest animal relatives. Chimpanzees, for example, rarely make it past age 50, despite sharing almost 99% of our genetic code.

Oxford University and AstraZeneca resume COVID-19 vaccine trial

More than a hundred candidate vaccine trials against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), are underway. About 35 are now undergoing clinical evaluation, and of these, nine are in the final phase of human trials, including the vaccine developed by Oxford University and the biopharmaceutical firm, AstraZeneca.

AstraZeneca COVID-19 vaccine trial paused due to suspected adverse reaction

The coronavirus disease (COVID-19) pandemic is rippling across the globe, with over 27.47 million reported cases. With the vast spread of the virus, scientists are racing to gain the approval of candidate vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 disease and Multisystem Inflammatory Syndrome in Children (MIS-C).

Single dose nasal vaccine against SARS-CoV-2 shows promise in animal studies

Now researchers at the Washington University School of Medicine in St. Louis have worked on developing a candidate vaccine against the infection that could be administered in a single dose via a nasal spray rather than an injection. In their preliminary studies using lab mice, this single dose of the nasal vaccine successfully prevented the infection with the novel coronavirus.

Silver strands and graying hair are not signs of aging in chimpanzees

Silver strands and graying hair is a sign of aging in humans, but things aren't so simple for our closest ape relatives--the chimpanzee. A new study published today in the journal PLOS ONE by researchers at the George Washington University found graying hair is not indicative of a chimpanzee's age.
