Dr. Sucharit Bhakdi und seine Frau Dr. Karina Reiss haben wunderbare Neuigkeiten. Sie berichten begeistert von jüngst veröffentlichten Studienergebnissen, die, wie sie sagen, die entscheidende Nachricht des Jahres beinhalten: "Alle Menschen haben bereits die so gewünschte Herdenimmunität. Nicht 75% der Personen, sondern über 90% – ohne, dass man impfen muss." "Also das, was die Impfung eigentlich bewerkstelligen sollte, hat der menschliche Körper schon gebildet?", frage ich nach. – "Das haben diese Studien gezeigt!" An diesem Tag der Freude, wie der Immunologe ihn nennt, sprechen die beiden Wissenschaftler mit mir über das Prinzip der erworbenen Immunität, Antikörper, über schützende Lymphozyten, und das vortrainierte Immunsystem. Gegen den Irrweg der Impfkampagne erheben Bhakdi und Reiss schwere Vorwürfe, ebenso wie gegen die verkommenen Institutionen dieses Landes. Ein Land, in dem man zwar seine Meinung äußern kann, dann jedoch mit entsprechenden Strafmaßnahmen zu rechnen hat. Ein Land, welches sie verlassen werden, falls ihr letzter Ausweg scheitert: die politische Initiative. Prof. Dr. Sucharit Bhakdi ist deutscher Facharzt für Infektionsepidemiologie und Mikrobiologie. Er studierte Humanmedizin an der Universität Bonn, war bis zu seinem Ruhestand Professor an der Universität Mainz und leitete bis dahin das Institut für medizinische Mikrobiologie und Hygiene. Seine wissenschaftlichen Forschungen wurden mehrfach ausgezeichnet. Prof. Dr. Karina Reiss ist deutsche Biochemikerin und Hochschullehrerin. Sie promovierte und habilitierte an der Medizinischen Fakultät der Universität Kiel, im Fach Biochemie. Beide sind Eltern eines gemeinsamen Sohnes.

When will vaccines for children be available? ➡️ Pfizer anticipates having initial results of lower-dose Phase 2/3 trials in September for 5- to 11-year-old kids; results for kids 2-<5 shortly after; kids 6-<24 months old in October or November. #COVID19 https://t.co/F1dEYZNhZt

Objective To estimate changes in life expectancy in 2010-18 and during the covid-19 pandemic in 2020 across population groups in the United States and to compare outcomes with peer nations. Design Simulations of provisional mortality data. Setting US and 16 other high income countries in 2010-18 and 2020, by sex, including an analysis of US outcomes by race and ethnicity. Population Data for the US and for 16 other high income countries from the National Center for Health Statistics and the Human Mortality Database, respectively. Main outcome measures Life expectancy at birth, and at ages 25 and 65, by sex, and, in the US only, by race and ethnicity. Analysis excluded 2019 because life table data were not available for many peer countries. Life expectancy in 2020 was estimated by simulating life tables from estimated age specific mortality rates in 2020 and allowing for 10% random error. Estimates for 2020 are reported as medians with fifth and 95th centiles. Results Between 2010 and 2018, the gap in life expectancy between the US and the peer country average increased from 1.88 years (78.66 v 80.54 years, respectively) to 3.05 years (78.74 v 81.78 years). Between 2018 and 2020, life expectancy in the US decreased by 1.87 years (to 76.87 years), 8.5 times the average decrease in peer countries (0.22 years), widening the gap to 4.69 years. Life expectancy in the US decreased disproportionately among racial and ethnic minority groups between 2018 and 2020, declining by 3.88, 3.25, and 1.36 years in Hispanic, non-Hispanic Black, and non-Hispanic White populations, respectively. In Hispanic and non-Hispanic Black populations, reductions in life expectancy were 18 and 15 times the average in peer countries, respectively. Progress since 2010 in reducing the gap in life expectancy in the US between Black and White people was erased in 2018-20; life expectancy in Black men reached its lowest level since 1998 (67.73 years), and the longstanding Hispanic life expectancy advantage almost disappeared. Conclusions The US had a much larger decrease in life expectancy between 2018 and 2020 than other high income nations, with pronounced losses among the Hispanic and non-Hispanic Black populations. A longstanding and widening US health disadvantage, high death rates in 2020, and continued inequitable effects on racial and ethnic minority groups are likely the products of longstanding policy choices and systemic racism.

The global race to develop a COVID-19 vaccine is on. Here are the different types of vaccines and how your body uses them to develop immunity.

Since the start of the COVID-19 pandemic, SARS-CoV-2 has caused millions of deaths worldwide. While many vaccines have been deployed to date, the continual evolution of the viral receptor-binding domain (RBD) has challenged their efficacy. In particular, emerging variants B.1.1.7 (U.K.), B.1.351 (South Africa) and P.1 (Brazil) have compromised convalescent sera and immunotherapies that received emergency use authorization1–3. One potential alternative to avert viral escape is the use of camelid VHHs or nanobodies, which can recognize epitopes often inaccessible to conventional antibodies4. Here, we isolate anti-RBD nanobodies from llamas and “nanomice” we engineered to produce VHHs cloned from alpacas, dromedaries and camels. We identified two sets of highly neutralizing nanobodies. Group 1 circumvents antigenic drift by recognizing an RBD region that is highly conserved in coronaviruses but rarely targeted by human antibodies. Group 2 is almost exclusively focused to the RBD-ACE2 interface and fails to neutralize variants carrying E484K or N501Y substitutions. Notably however, group 2 nanobodies retain full neutralization activity against variants when expressed as homotrimers, rivaling the most potent antibodies produced to date against SARS-CoV-2. These findings suggest that multivalent nanobodies overcome SARS-CoV-2 mutations through two separate mechanisms: enhanced avidity for the ACE2 binding domain, and recognition of conserved epitopes largely inaccessible to human antibodies. Therefore, while new SARS-CoV-2 mutants will continue to emerge, nanobodies represent promising tools to prevent COVID-19 mortality when vaccines are compromised.

On May 19, 2021, the Delta Variant of Concern (VOC), formerly known as the Indian VOC or B 1.617.2, became the dominant strain of SARS-CoV-2 in Scotland. The Alpha VOC (formerly known as the Kent VOC, B.1.1.7, or S gene negative) had been the dominant strain previously, but it has rapidly been replaced (appendix p 1).

The COVID-19 pandemic is seemingly driving birthrates down – but it's not the only thing behind the global fertility decline. Here's what's behind it and why it matters.

The global race to develop a COVID-19 vaccine is on. Here are the different types of vaccines and how your body uses them to develop immunity.

But in the days following the start of the vaccination campaign, a new development became evident: Several of the recently vaccinated HCWs developed symptoms of Covid-19, and an infection with SARS-CoV-2 was confirmed by PCR. Of the 1306 HCWs who had received a first dose of the vaccine by January 18th, 2021, seven HCWs tested positive. A symptomatic infection was confirmed on day two, four, seven, eleven, sixteen, seventeen and nineteen after receiving the first dose, respectively. The recently vaccinated made up 35% of the total number of the 20 employees of the University Hospital who tested positive in that time period, meaning the recently vaccinated were overrepresented among those with a symptomatic infection. Of those who had been inoculated and later tested positive, some may have already been in the incubation period when receiving the vaccine, but others likely became infected shortly after receiving the first dose.

With the COVID-19 pandemic now ongoing for close to a year, people all over the world are still waiting for a vaccine to become available. The initial…
