A study of continuous monthly mortality data found that excess deaths associated with COVID-19 reached greater peaks than most other periods of excess deaths since 1918. The relative excess of deaths in 2020 was 12.5% in Switzerland, 8.5% in Sweden, and 17.3% in Spain.
Researchers at MIT have developed a pill that can deliver RNA to the stomach, potentially making vaccines easier to tolerate and treat gastrointestinal diseases. The capsule is designed to release RNA in the stomach, where it can stimulate an immune response without being degraded by digestive enzymes.
Researchers found that current COVID-19 vaccines provide robust protection against severe disease caused by the Omicron variant through induced cellular immunity. The study showed that CD8+ T cell responses were over 80% cross-reactive with the original strain, suggesting a key role in vaccine protection.
A large real-world study published by Israel's Clalit Research Institute found that parental vaccination with the BNT162b2 vaccine decreased the risk of infection for unvaccinated children by 58.1%, regardless of household size or child age. Vaccination also reduced transmission from infected parents to their unvaccinated children.
A new study found that the Pfizer vaccine was 91% effective in reducing coronavirus transmission in Israeli households before the emergence of the delta variant. However, with waning immunity, the vaccine's effectiveness decreased to only 40% against infection and transmission.
Patients under immunosuppressive therapy have increased risk of severe COVID-19 disease courses if they don't respond to primary vaccination. A recent study found that a third booster vaccination is safe and effective in these patients, who were initially unable to produce antibodies after vaccination.
Two observational studies provide reassuring data on menstrual changes after COVID-19 vaccination, finding that any changes are short-lived and small. The studies, which drew from US and Norwegian data, suggest that cycle lengths return to normal by two cycles after vaccination.
A new portable $51 testing kit can provide fast and reliable COVID-19 detection in resource-poor regions, refugee camps, and disaster zones. The non-invasive saliva sampling system uses a technique similar to PCR testing, with costs comparable to commercial tests.

The researchers suggest that language choice shou...
A University of Massachusetts Amherst study found that vaccinated women transfer SARS-CoV-2 antibodies to their breastfed infants, potentially giving them passive immunity against the coronavirus. The research also showed a correlation between vaccine side effects and antibody levels in infant stool.
The study investigated the antibody response to 2 or 3 doses of the BioNTech-Pfizer vaccine in patients with solid tumors treated with anticancer agents. The researchers found that higher antibody levels were associated with better immune response and reduced risk of severe COVID-19.
A registry study found that people with inflammatory RMDs, such as rheumatoid arthritis and psoriatic arthritis, tolerate their COVID vaccine well, with short-lived reactions being the most common side effect. The majority of participants were able to continue on their normal medication with no changes.
A NIH-funded study discovered a small, temporary increase in menstrual cycle length among women receiving COVID-19 vaccine. The average increase was less than one day, with no change in bleeding days.
A booster dose of mRNA COVID-19 vaccine is required to provide immunity against the Omicron variant of SARS-CoV-2, according to a study. The traditional dosing regimens of COVID-19 vaccines available in the US do not produce antibodies capable of recognizing and neutralizing the Omicron variant.
Researchers developed a color-coded test that quickly signals whether medical nanoparticles deliver their cargo into target cells. The tool, tested in mouse cells and living mice, assesses nanoparticle formulations on their ability to escape cellular defenses and reach the cell's interior.
A study published in JAMA Internal Medicine found that people with immune dysfunction, such as HIV infection or rheumatoid arthritis, had a higher rate of COVID-19 breakthrough infections after vaccination. These individuals also experienced worse outcomes compared to those without immune dysfunction.
A study of fully vaccinated patients with cancer who experienced breakthrough COVID-19 found a 13% mortality rate. Fully vaccinated patients were at high risk for hospitalization and death, even after receiving booster vaccines.
Recent studies have shown that booster doses can restore vaccination effectiveness to over 90% in protecting against SARS-CoV-2 variants. However, continued research highlights the importance of nonpharmaceutical interventions such as mask-wearing and social distancing in reducing COVID-19 cases and limiting variant emergence.
A phase 3 trial has shown that one dose of the Ad5-nCoV COVID-19 vaccine is highly effective against severe disease, with an efficacy rate of 91.7% at 28 days post-vaccination. The vaccine has also been found to be safe, with no serious vaccine-related adverse events or deaths reported among trial participants.
A new study reveals that mRNA vaccines activate a type of helper cell called T follicular helper cells, which assist in creating powerful antibodies and drive the development of immune memory. This strong response helps prevent severe disease and death, even against highly mutated variants like omicron.
A study of 18 Connecticut colleges found that COVID-19 cases were associated with higher social contact and lower testing rates. The authors suggest that colleges should continue testing residential students and implementing mitigation strategies.
A new study finds that the Omicron variant can evade immunity from previous infections and vaccines, with antibodies from double-vaccinated individuals showing reduced neutralizing activity. The study suggests the need for new vaccines and treatments to combat evolving variants.
A study of nearly 20,000 adults found that serious COVID-19 vaccine side effects are extremely rare among those who received vaccination. The online survey collected data on health and COVID-19-related events for daily, weekly, and monthly periods.
