A Vaccine Against COVID-19 Found to Protect Against Infection and Brain Damage Caused by the Virus
(Neuroscience News) Although the pathology of the respiratory system is the main impact of COVID-19, many patients also manifest important neurological symptoms, such as loss of smell (anosmia), headaches, malaise, cognitive loss, epilepsy, ataxia and encephalopathy, among others. However, this effect on the nervous system by the coronavirus has not been characterized in detail and […]

A survey of COVID-19 vaccine acceptance across 23 countries in 2022
(Nature) Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continued to mutate and spread in 2022 despite the introduction of safe, effective vaccines and medications. Vaccine hesitancy remains substantial, fueled in part by misinformation. Our third study of Coronavirus Disease 2019 (COVID-19) vaccine hesitancy among 23,000 respondents in 23 countries (Brazil, Canada, China, Ecuador, France, Germany, […]

Comparative effectiveness of third doses of mRNA-based COVID-19 vaccines in US veterans
(Nature) Vaccination against SARS-CoV-2 has been effective in reducing the burden of severe disease and death from COVID-19. Third doses of mRNA-based vaccines have provided a way to address waning immunity and broaden protection against emerging SARS-CoV-2 variants. However, their comparative effectiveness for a range of COVID-19 outcomes across diverse populations is unknown. We emulated […]

SARS-CoV-2 mucosal vaccine
(Nature) Currently approved SARS-CoV-2 vaccines induce robust systemic immunity but poor immunity at the respiratory mucosa, meaning that they are highly effective against symptomatic disease but do not prevent viral transmission. In Science, Mao et al. developed a vaccine strategy that induced mucosal immune memory within the respiratory tract and reduced viral transmission. K18-hACE2 mice were […]

Cancer Patients Particularly Vulnerable to Lack of COVID Vax Response
(MedPageToday) Cancer patients vaccinated against COVID-19 had a significantly higher rate of negative antibody tests as compared with a vaccinated control population, greatly increasing the odds for breakthrough infection and hospitalization, a large British study showed. Among people who had received two doses of COVID-19 vaccine, 4.68% of 4,249 tests for patients with cancer had […]

The Magic of mRNA Will Push Medical Advances for Everyone
(Wired) mRNA is one of the first molecules of life. While identified six decades ago as the carrier of the blueprint for proteins in living cells, its pharmaceutical potential was long underestimated. mRNA appeared unpromising—too unstable, too weak in potency, and too inflammatory. The successful development of the first mRNA vaccines against Covid-19 in 2020 was an […]

COVID-19 vaccine patent battles continue into 2023
(Reuters) A tangle of high-stakes U.S. patent disputes over COVID-19 vaccines could be tamed by court rulings or grow even more complex next year. In the headlining fight, Moderna sued Pfizer and BioNTech in August, accusing them of infringing three patents on mRNA-related innovations Moderna said it developed before the COVID-19 pandemic. Pfizer and BioNTech responded earlier this month […]
