People of all age groups benefit more from COVID-19 vaccines than natural immunity, real-world study finds

In one of the first large, real-world studies comparing the effectiveness of COVID-19 vaccines versus natural immunity in protecting against death, hospitalizations and emergency department (ED) visits for any cause, including COVID, research-scientists from Regenstrief Institute, Indiana University School of Medicine and Vanderbilt University Medical Center report that people of all age groups benefited significantly more from vaccination than natural immunity acquired from a previous COVID infection.

Researchers report the development of robust candidate single immunization PNP hydrogel COVID vaccines

Researchers developed a one-dose subunit vaccine for the induction of durable, potent, and broad immunity against SARS-CoV-2.

Study finds anti-S binding antibody levels are a valid correlate of protection against Omicron BA.1/BA.2 infections

Researchers used serological measurements from a longitudinal cohort to evaluate the use of binding antibodies against the SARS-CoV-2 spike protein receptor binding domain as correlates of protection against the immune evasive Omicron subvariants BA.1 and BA.2.

The impact of the US vaccination program on reducing infections, hospitalizations, and deaths

A recent study reported that in the two years following the initiation of the US COVID-19 vaccination campaign, over 18 million hospitalizations and three million deaths have been prevented, and close to $1.15 trillion have been saved in medical costs.

Guidance on the use of face masks and on outbreaks in care settings has been updated

Guidance on the use of face masks in all care settings and on outbreaks in care homes has been updated to give settings the flexibility to ensure ongoing Covid measures are proportionate.

Eating flowers to promote health and prevent disease

Do people eat flowers? Yes, many of them. Experts say that the Greeks, Romans, and French during the Middle Ages and the English during the Victorian era included edible flowers in their cuisine, either as appetizers or to enhance the flavor of the dish.

Sheep milk could be an inexpensive source of therapeutic polyclonal SARS-CoV-2 neutralizing antibodies

Researchers used sheep, a ruminant mammal, to obtain polyclonal immunoglobulins (IgGs) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Study assesses COVID-19 booster vaccination coverage by demographics and behaviors and experiences toward vaccination among fully vaccinated adults

An early release from the CDC, USA, examines the coverage of booster doses among adults in the USA.

Novel experimental system traces the development and longevity of plasma cells

Just as a fire department mobilizes in response to a reported fire, specialized immune cells in the body mobilize in response to the introduction of foreign substances known as antigens.

The implications of pulmonary tissue-resident memory T lymphocytes in COVID-19 and other respiratory diseases

Researchers elucidated the mechanisms of long-term T lymphocyte lodgement in tissues other than lymphoid tissues and the reasons for the transient residency of specific subsets of tissue-resident memory T (TRM) lymphocytes.

The evolution of COVID-19 mortality during 2020 and 2021 in six countries

Researchers analyzed the mortality in selected countries during multiple waves of the COVID-19 pandemic in 2020 and 2021 to understand the evolution of COVID-19-related mortality according to age and sex.

14 Dec 2022

Polymorphisms in human immunoglobulin heavy chain genes can influence the function of SARS-CoV-2 neutralizing antibodies

Researchers isolated SARS-CoV-2 spike protein-targeted mAbs from convalescent healthcare workers, emphasizing the IGHV1-69 gene, the gene with the greatest structural and allelic variation.

14 Dec 2022

Study indicates need for developing mucosal vaccines to induce potent immune responses at sites where SARS-CoV-2 infection occurs

Researchers measured the antibodies against SARS-CoV-2 from nasal fluid, saliva, and plasma to compare the antibody levels between blood and mucosal fluids.

Nanomaterial can indirectly affect the immune system via the gut microbiome, study shows

The nanomaterial graphene oxide - which is used in everything from electronics to sensors for biomolecules - can indirectly affect the immune system via the gut microbiome, as shown in a new study on zebrafish by researchers at Karolinska Institutet in Sweden.
