A few days ago I used the Bird Button to tweet a link to a JWatch article. Today I decided to embed my previous tweet to see what it looks like on the blog.
Embedment is an easy way to blog. Looks good too.
A total of 800 adults aged 18 to 55 or aged 65 and up were randomized to various combinations of low-dose or high-dose vaccines or placebo, given 56 days apart.
Adverse events were common, with fatigue, headache, myalgia, and injection-site pain reported most often. At day 29 after the first dose, the seroconversion rate was 99% or more in the younger cohort across dosing groups. Older vaccine recipients had a 96% seroconversion rate. At 57 days after the first dose, antibody titers had increased further.COVID-19: Single Dose of J&J Vaccine / Plasma / New Testing Requirement — https://www.jwatch.org/fw117413/2021/01/13/covid-19-single-dose-j-j-vaccine-plasma-new-testing
The J&J vaccine is in a multi-center, placebo-controlled, phase 1–2a trial. Here’s the link to the NEJM article https://www.nejm.org/doi/full/10.1056/NEJMoa2034201
From Stat Phase 3 results are coming soon.
There are two Phase 3 studies running. A 40,000-volunteer study of the one-dose vaccine, conducted in the U.S., is set to read out in the next two weeks. A second, equally big study is being conducted using the same vaccine given as two doses, each administered 57 days apart, in case the vaccine does not prove effective in a one-dose regimen or there are other advantages, such as the durability of the vaccine, to giving a second dose.https://www.statnews.com/2021/01/13/data-fuel-debate-over-whether-jjs-one-dose-covid-vaccine-will-measure-up/ — Data fuel debate over whether J&J’s one-dose Covid vaccine will measure up
And from the Medscape article.
Unlike the Pfizer/BioNTech and Moderna messenger RNA vaccines, the Johnson & Johnson product is a recombinant, replication-incompetent adenovirus serotype 26 (Ad26) vector encoding a full-length and stabilized SARS-CoV-2 spike (S) protein.The Next Likely COVID-19 Vaccine Has Its Advantages — https://www.medscape.com/viewarticle/944151?src=rss
Immune responses to SARS-CoV-2 might last for years, according to a study posted on the preprint server bioRxiv.
Some 185 adults who recovered from COVID-19 (most had mildly symptomatic disease) provided blood samples for analysis. The majority provided a single sample, but roughly 20% provided multiple samples over several months.
The researchers found that levels of spike-specific memory B cells (which make antibodies as needed) increased with time — and were higher at 4–6 months than at earlier time points in most participants who gave multiple samples. In addition, SARS-CoV-2 spike IgG titers were generally stable, showing only modest declines at 6–8 months.COVID-19: Study Suggests Durable Immune Response After SARS-CoV-2 Infection — https://www.jwatch.org/fw117245/2020/11/17/covid-19-study-suggests-durable-immune-response-after
I hope these findings are replicated in other studies.
Over the past week, U.S. researchers reported a secondary infection rate of 53% among household contacts of people with COVID-19. In another study, risk factors for transmission among close contacts of infected people — like sharing a vehicle or being spoken to by the infected person within 2 meters — were detailed. Elsewhere, the FDA warned about false-positives with rapid antigen tests for SARS-CoV-2. And in Denmark, all farmed minks were set to be killed after reports that a SARS-CoV-2 mutation had jumped from minks to humans.https://www.jwatch.org/fw117204/2020/11/07/latest-covid-19-news-week-ending-nov-7

Meanwhile in El Paso…
EL PASO, Texas — The massive Covid-19 surge in El Paso County went from extremely bad to critically worse on Saturday as all-time highs were shattered for a half-dozen critical markers: New cases, active infections, positivity rate, and hospitalizations – along with ICU and ventilator usage.
The health department reported a record 1,216 new cases on Saturday, as well as 75 unreported cases from earlier, increasing the total number of additional cases reported to 1,291. The number of active infections jumped to just shy of 11,000 at a record-level of 10,911.
There were a record 715 patients in El Paso hospitals due to Covid-related illness as of Saturday morning, representing nearly 2% of hospitalizations nationwide. El Paso hospitals have seen a staggering 203% increase in Covid patients over the past two weeks. In addition, record numbers of virus patients Saturday required intensive care (199) and the use of ventilators (85).El Paso shatters records for new & active virus cases, positivity rate, hospitalizations, ICUs, ventilators — https://kvia.com/coronavirus/2020/10/24/el-paso-shatters-all-time-highs-for-new-active-virus-cases-positivity-rate-hospitalizations-icus-ventilators/
